Chlorosulfonated Polyethylene (CSM): Properties, Applications & Selection Guide
Chlorosulfonated polyethylene (CSM) is a specialty synthetic rubber selected for demanding outdoor and chemical environments. It is valued for strong ozone, sunlight, weathering and oxidation resistance, together with useful resistance to many inorganic chemicals. Final performance depends on the polymer grade, compound formulation, cure system, service medium, temperature and product construction, so the name CSM alone is not a complete material specification.
CSM Fundamentals
What Is Chlorosulfonated Polyethylene Rubber?
CSM is produced by chemically modifying polyethylene through chlorination and chlorosulfonation. The resulting elastomer combines a saturated main chain with reactive cure sites, helping properly compounded CSM resist ozone, oxygen, sunlight and outdoor weathering while also providing useful chemical and heat resistance.
CSM is the standardized material abbreviation used for chlorosulfonated polyethylene rubber. CSPE is also used in industry, particularly when describing the polymer or coated-fabric constructions. Hypalon® was a trade name historically associated with CSM products; it should not be used as a complete generic compound specification.
“CSM” still describes a material family rather than one fixed recipe. Polymer grade, chlorine and sulfur levels, viscosity, fillers, plasticizers, pigments, stabilizers, cure package and processing conditions all influence the finished compound. The application must therefore be matched to an actual compound and validation plan.
CSM is usually a strong candidate when
- The part must withstand ozone, sunlight and long-term outdoor weather.
- Oxidation resistance and useful heat resistance are important.
- The application contacts compatible acids, alkalis or inorganic chemicals.
- A durable protective cover, coated fabric, cable jacket or industrial gasket is required.
CSM needs another look when
- The medium contains ketones, esters, aldehydes or aggressive aromatic or halogenated solvents.
- Petroleum oil or fuel resistance is the dominant requirement without compound test data.
- Very low-temperature flexibility is critical and no validated grade is specified.
- The requirement assumes every CSM compound is automatically flame-retardant or certified.
Performance Profile
What Are the Key Properties of CSM Rubber?
CSM is best understood as a durable outdoor and chemical-environment elastomer. Its strongest selection case is the combined requirement for ozone, weathering, oxidation and chemical resistance—not one isolated property. Mechanical, sealing, flame and low-temperature performance still depend on the exact compound and product construction.
Ozone & Weathering
CSM is widely recognized for strong resistance to ozone, sunlight and adverse atmospheric exposure, making it useful for long-life outdoor components.
Oxidation & UV
Its saturated backbone supports good resistance to oxygen and ultraviolet exposure. Actual color and property retention remain formulation- and exposure-specific.
Acids & Inorganic Chemicals
Selected CSM compounds perform well with many acids and inorganic chemicals. Concentration, oxidizing strength, temperature and immersion time must be checked.
Heat & Abrasion
CSM can provide useful heat and abrasion resistance for protective components, sheeting and coated fabrics, but it is not a universal high-temperature or wear material.
Color & Surface
CSM can be compounded in black or selected colors for outdoor products. Pigment, surface finish and color-retention requirements should be defined for the project.
Flame Behavior
Some commercial CSM compounds are formulated for flame resistance or self-extinguishing behavior. No flame rating should be assumed without a named test method and result.
Polymer & Compound Design
What Distinguishes CSM Grades and Compounds?
CSM grades differ in polymer chemistry, viscosity and cure-site level, while finished compounds add fillers, plasticizers, pigments, stabilizers and a cure package. These variables change processing, hardness, mechanical properties, chemical resistance, low-temperature behavior, appearance and long-term aging.
A raw-polymer trade name or a generic “CSM 60” description is not enough for a critical custom part. The purchasing specification should identify the required finished-compound properties and service tests, leaving the producer to select a suitable grade and formulation unless a customer-approved compound is mandatory.
| CSM Variable | What It Can Influence | Why It Matters |
|---|---|---|
| Polymer chlorine level | Polarity, chemical response, flexibility and crystallization tendency | The effect is grade-specific and must be evaluated through finished-compound data. |
| Cure-site level | Vulcanization response, cure speed and crosslink structure | Must match the selected curatives, process and property targets. |
| Polymer viscosity | Mixing, extrusion, coating, mold flow and green strength | Influences whether a grade is suitable for the intended manufacturing route. |
| Fillers and reinforcing agents | Hardness, modulus, strength, abrasion, cost and processability | Explains why two CSM compounds at similar hardness can perform differently. |
| Plasticizer system | Flexibility, low-temperature behavior, hardness and extraction risk | Compatibility with the service medium and aging conditions must be reviewed. |
| Pigments and stabilizers | Color, UV response, heat aging and appearance retention | Light-colored or appearance-critical products need an agreed exposure requirement. |
| Cure package | Compression set, heat aging, bond performance and production control | It is part of the compound specification, not a separate quality label. |
| Product construction | Solid rubber, sheet, coated fabric, bonded or reinforced component behavior | A CSM coating cannot be specified like a homogeneous molded rubber part. |
Engineering note: material selection should be based on the cured CSM compound and finished product construction, not only on the raw polymer grade or former trade name.
Vulcanization
How Do Cure System and Formulation Affect CSM?
CSM uses reactive chlorosulfonyl groups as cure sites. Metal-oxide-based cure systems have long been associated with CSM, while the actual commercial cure package can include accelerators, acid acceptors and other formulation components. The correct system depends on polymer grade, processing route, performance targets and regulatory restrictions.
| Compound Factor | Performance / Processing Effect | RFQ Implication |
|---|---|---|
| Metal-oxide cure system | Supports crosslinking through the polymer's cure sites; cure rate and properties depend on the complete package. | Do not specify one oxide or recipe unless required by an approved material standard. |
| Accelerator package | Changes scorch safety, cure speed and state of cure. | Processing window and residual-substance limits may need review. |
| Acid acceptors / stabilizers | Help manage compound stability and aging during processing and service. | Define heat-aging or chemical-exposure requirements rather than prescribing ingredients without need. |
| Filler and plasticizer balance | Changes hardness, modulus, flexibility, tensile properties and extraction behavior. | Specify measurable finished-compound properties and actual media. |
| Cure time and temperature | Under-cure or excessive thermal history can affect set, strength, surface and bonding. | Production controls should be validated for the actual part thickness and tool. |
| Bonding / coated-fabric system | The rubber cure must be compatible with fabric treatment, adhesive, substrate and lamination conditions. | Specify peel, adhesion, seam or durability tests when bond performance is critical. |
Durometer Selection
What CSM Hardness Should You Choose?
CSM does not have one standard hardness. The correct value depends on whether the product is a compressed gasket, protective cover, hose layer, cable jacket, molded component, sheet or coated fabric. Available hardness and tolerance must be confirmed against the selected compound and manufacturing route.
Hardness affects conformity, closure force, deformation, extrusion resistance, handling and abrasion response. It does not by itself define ozone resistance, chemical compatibility, flame behavior, tensile strength or service life. Those requirements must be specified separately.
Lower Hardness
Can improve conformity and flexibility, but may increase deformation, handling difficulty or extrusion risk depending on geometry and load.
Medium Hardness
May provide a practical balance for general molded parts, gaskets, profiles and protective components when verified against the application.
Higher Hardness
Can improve dimensional support and resistance to deformation, but normally increases compression or assembly force and may reduce flexibility.
Specify the hardness method, nominal value and tolerance on the approved material specification. ISO 48-4 or ASTM D2240 are commonly used for Shore durometer testing of vulcanized rubber.
Thermal Limits
What Temperature Range Can CSM Rubber Handle?
There is no universal CSM temperature range. One current commercial CSM sheeting family publishes approximately -35°C to +125°C, but that figure belongs to those products and should not be applied automatically to every molded, extruded, coated or bonded CSM component.
Low-temperature flexibility, continuous heat aging, short peaks, chemical exposure, compression, movement and product thickness must be evaluated together. A material can survive a temperature excursion yet fail to seal, flex or retain adhesion at that same temperature.
Low Temperature
Define whether the part must only survive storage or must flex, seal, fold or absorb movement. Grade and plasticizer selection influence low-temperature behavior.
Continuous Heat
Long exposure can change hardness, elongation, compression set, color and bond performance. Use compound-specific aged-property limits.
Peak Temperature
State the peak value, duration and frequency. A short excursion must not be converted into a continuous-service rating without test data.
Hot Chemical Exposure
Chemical attack and extraction can accelerate at elevated temperature. Compatibility data should match the actual concentration, temperature and exposure time.
Media Compatibility
Which Chemicals and Fluids Are Compatible With CSM?
CSM is used with many inorganic chemicals, acids and outdoor environments, but “chemical resistant” does not mean universal compatibility. Concentration, oxidizing strength, contamination, temperature, pressure and exposure time can change swelling, hardness, tensile properties, surface condition and bond durability.
| Medium / Environment | General CSM Direction | Engineering Note |
|---|---|---|
| Ozone / sunlight / outdoor weather | Generally excellent | Core CSM strength; define exposure duration, strain, color and acceptance criteria. |
| Dilute and low-oxidizing acids | Often strong | Verify acid identity, concentration, temperature and whether exposure is splash or immersion. |
| Many inorganic chemicals | Often strong | Compound data and actual-media testing remain necessary for critical service. |
| Alkalis | Often useful | Review concentration, temperature, contaminants and long-term volume or property change. |
| Water / saltwater | Often useful | For coated fabrics and membranes, seams, reinforcement, adhesive and hydrolysis resistance also matter. |
| Alcohols | Often useful | Confirm the exact alcohol, purity, additives and operating temperature. |
| Mineral oils / greases | Compound-specific | Published guidance ranges from fair to useful depending on compound and fluid; validate the exact service medium. |
| Concentrated oxidizing acids | High caution | Strong general acid resistance does not guarantee resistance to concentrated oxidizers. |
| Ketones / esters / aldehydes | Often unsuitable | These media are commonly listed as CSM attack risks; use exact-fluid immersion data. |
| Halogenated / nitro hydrocarbons | Often unsuitable | Do not use a general CSM rating as approval for these solvent families. |
| Aliphatic / aromatic hydrocarbons | Requires review | Suitability varies with hydrocarbon type and formulation; swelling can limit sealing performance. |
Material Selection
CSM vs. EPDM, CR and NBR: Which Should You Use?
CSM is a specialty choice when weathering, ozone, oxidation and chemical exposure must be balanced. EPDM is often preferred for outdoor, water and glycol duties; CR offers a broad weathering and moderate oil-resistance balance; NBR is the stronger starting point for petroleum oils. The actual medium and function decide the material.
| Selection Factor | CSM | EPDM | CR / Neoprene | NBR |
|---|---|---|---|---|
| Ozone / outdoor weather | Excellent starting point | Excellent | Good to very good | Limited without protection |
| Oxidation / sunlight | Strong | Strong | Good | Limited to moderate |
| Many acids / inorganic chemicals | Often strong; chemistry-specific | Often strong in aqueous media | Moderate to good; compound-specific | Application-specific |
| Petroleum oils / greases | Fair to useful; compound-specific | Generally poor | Moderate | Strong starting point |
| Water / glycol service | Often useful; validate construction | Often a strong starting point | Often useful | Compound-specific |
| Flame-resistant compounds | Available; test-specific | Special formulations required | Available; test-specific | Special formulations required |
| Supply / cost position | Specialty material | Widely available and often economical | General specialty elastomer | Widely available and often economical |
This comparison is directional. Final material selection requires the exact compound, chemical, temperature, pressure, motion, outdoor exposure, expected life and applicable specification.
Industrial Applications
Where Is CSM Rubber Used?
CSM is used where a component or protective layer must retain performance in outdoor, oxidizing or chemically demanding conditions. It appears in solid rubber parts, sheeting, coatings and reinforced constructions, so the complete product design matters as much as the polymer family.
Outdoor Seals & Gaskets
Custom gaskets, seals, profiles and protective parts exposed to sunlight, ozone, rain and changing outdoor temperatures.
Coated Fabrics & Inflatable Structures
CSM coatings are used on reinforced fabrics for demanding outdoor and marine constructions. Fabric, coating, seam and adhesive specifications must be evaluated together.
Cable Jackets & Electrical Protection
Protective cable layers and components where weather, ozone, heat, chemicals or flame behavior must be controlled by the finished compound and cable specification.
Chemical-Industry Protection
Sheeting, gaskets, covers and equipment-protection parts used with compatible acids, alkalis or inorganic chemicals after application-specific review.
Hoses & Expansion Joints
Selected hose covers, linings and reinforced flexible connectors use CSM where the media and external environment match the complete construction.
Roofing & Waterproofing
CSM-based membranes and bands can be used in weather-exposed waterproofing systems. Seams, substrate preparation, adhesive and movement design remain critical.
Failure Analysis
Why Do CSM Parts Crack, Swell, Harden or Lose Adhesion?
CSM failures usually reflect a mismatch between compound, chemical, temperature, stress, product construction and installation. Chemical swelling, heat hardening, flex cracking, compression set, coating delamination and seam failure each indicate a different mechanism and should be investigated separately.
Strong weather resistance does not make CSM immune to all outdoor failures. Excessive strain, sharp folds, poor seam design, incompatible adhesive, substrate contamination, concentrated chemicals or temperatures outside the validated range can still cause premature damage.
| Observed Symptom | Possible Causes | What to Review |
|---|---|---|
| Swelling / softening | Incompatible solvent, oil, fuel or mixed chemical; elevated temperature | Exact medium, concentration, temperature, immersion data and volume change. |
| Hardening / embrittlement | Excessive heat, oxidizing chemical, extraction or prolonged aging | Aged hardness, elongation, exposure history and compound temperature rating. |
| Surface cracks | Excessive strain, flex fatigue, sharp bend, heat aging or unsupported material choice | Crack location, strain condition, flex cycles, thickness and surface defects. |
| Permanent flattening / leakage | Compression set, over-compression, insufficient cure, heat or poor joint design | Gasket compression, flange movement, cure state and compression-set requirement. |
| Coating delamination | Weak fabric treatment, contamination, inadequate adhesion or chemical ingress | Fabric, coating weight, adhesion method, edge sealing and peel test. |
| Seam or joint opening | Wrong adhesive, poor surface preparation, peel stress or insufficient overlap | Joining process, cure, seam geometry, movement and environmental aging. |
| Unexpected burning / flame spread | Generic polymer assumption, wrong compound or unsupported flame claim | Exact standard, specimen construction, thickness, conditioning and certified result. |
Manufacturing
How Are Custom CSM Rubber Parts Manufactured?
CSM can be processed into molded parts, extruded profiles, calendared sheet, coated fabrics, reinforced flexible components and bonded assemblies. The manufacturing route depends on geometry, polymer grade, compound, substrate, tolerance, quantity, tooling and validation requirements.
- Application reviewConfirm chemicals, temperature, weather, ozone, movement, flame requirement, compliance and expected service life.
- Compound definitionSelect the CSM grade direction, hardness, color, cure approach and required original or aged properties.
- Tooling / process reviewChoose molding, extrusion, calendering, coating, cutting, bonding, joining or a combined process based on design and volume.
- Sample validationCheck dimensions, appearance, fit, adhesion and the agreed chemical, weathering or functional tests before approval.
- Production controlControl compound batch, cure, coating or bonding process, dimensions, appearance and traceability under the agreed plan.
Molded CSM
Suitable for custom gaskets, seals, covers, boots, pads and complex 3D parts when the compound and tooling match the geometry and volume.
Extruded CSM
Used for profiles, strips, cords and protective sections. Cross-sectional tolerance, surface, cut length and joining requirements should be specified.
CSM Sheet & Gaskets
Flat parts can be cut from suitable CSM sheet when grade, thickness, hardness, surface and chemical requirements are confirmed.
CSM-Coated Fabric
A CSM layer can protect a reinforcing textile. Fabric type, coating construction, adhesion, seams, flexing and permeability must be defined together.
CSM-to-Metal Bonding
Bonded parts require compatible substrate preparation, adhesive, compound and cure conditions. Bond testing should match the actual load and environment.
Secondary Operations
Cutting, joining, seam preparation, marking, inspection and packaging should be defined when they affect installation, cleanliness or performance.
Dimensions & Design
What Tolerances Can Be Achieved on CSM Parts?
There is no universal tolerance for CSM rubber. Achievable tolerances depend on part size, geometry, compound shrinkage, mold-dependent versus mold-independent dimensions, tool construction, process, flash or edge location, substrate and measurement method.
ISO 3302-1:2014 is a current reference for dimensional tolerances on molded, extruded and calendared solid rubber products. It does not apply to calendared composite products such as rubber-coated fabrics, so coated-fabric thickness, width, coating weight, adhesion, seams and construction tolerances must be specified separately.
Define Critical Characteristics
Identify sealing height, wall thickness, interfaces, hole positions, coating thickness, seam width or other dimensions that control function.
Separate Solid and Composite Parts
Do not apply solid-rubber tolerances automatically to coated fabrics, laminates or reinforced constructions with different process variation.
Agree Edge & Surface Criteria
Parting line, flash, gate, cut edge, coating appearance, wrinkles, seams and cosmetic limits should be defined separately from dimensions.
Confirm Measurement Method
Soft rubber and coated constructions deform under force. Define conditioning, datums, fixtures, contact pressure and thickness method where needed.
Validation & Quality
Which Tests Should Be Specified for CSM Rubber?
A useful CSM test plan starts with the dominant failure risk. Hardness and tensile data alone are not enough if the product must resist outdoor weathering, retain properties in acid, meet a flame requirement, maintain a seam or bond, or seal after prolonged compression.
| Property / Risk | Common Test Reference | What to Define |
|---|---|---|
| Hardness / tensile / elongation | ISO 48-4:2018, ISO 37:2024 / ASTM D2240, ASTM D412 | Scale, nominal or minimum values, specimen, conditioning and whether results are original or aged. |
| Compression set | ISO 815-1:2019 / ASTM D395 | Compression, time, temperature, recovery method and maximum result. |
| Heat aging | ISO 188:2023 / ASTM D573 | Temperature, duration and permitted hardness, tensile or elongation change. |
| Liquid / chemical resistance | ISO 1817:2024 / ASTM D471 | Exact chemical, concentration, temperature, duration and permitted mass, volume or property change. |
| Ozone resistance | ISO 1431-1:2024 / ASTM D1149 | Ozone concentration, strain, temperature, duration and cracking criteria. |
| Weathering / color change | ISO 4665:2016 / agreed exposure method | Natural or artificial exposure, duration, appearance and physical-property limits. |
| Adhesion to fabric / substrate | ISO 36:2020, ISO 813:2019 or agreed method | Construction, peel direction, specimen, aging condition and minimum adhesion. |
| Flame behavior | Exact product or customer standard | Specimen construction, thickness, conditioning, rating and third-party documentation if required. |
| Dimensions / appearance | Approved drawing and inspection plan | Critical dimensions, method, sampling, surface, edge, seam and visual criteria. |
Test standards and editions should be agreed in the purchase specification. Availability of any specific test, report or third-party laboratory service is to be confirmed for the project.
Regulatory & Documentation
Does CSM Automatically Meet Flame, FDA, RoHS or Other Requirements?
No. CSM is a polymer-family name, not a compliance statement. Commercial CSM products may be formulated for particular flame, drinking-water, environmental, marine, electrical or customer specifications, but generic CSM does not automatically meet any named regulation or approval.
If the project requires a flame classification, FDA food-contact requirement, drinking-water approval, RoHS, REACH, an electrical cable standard, marine approval, PPAP documentation or another customer specification, state the exact requirement at RFQ stage. Compound availability, color, construction, test scope and documentation must be confirmed before approval.
Purchasing Guide
What Information Should You Send for a CSM RFQ?
A quote can look complete but still carry material risk if it contains only “CSM, black” or “Hypalon rubber.” For a custom CSM part, the exact chemical, outdoor exposure, temperature, product construction and validation requirement are as important as hardness and geometry.
| RFQ Item | Information to Provide | Why It Matters |
|---|---|---|
| Geometry | 2D drawing, 3D model or physical sample; identify revision | Defines tooling, process, joining, dimensional risk and inspection. |
| Product / function | Solid molded part, extrusion, sheet, coated fabric, reinforced or bonded seal, gasket, cover, jacket, membrane or joint | Changes material form, tolerance, adhesion and validation requirements. |
| Chemical medium | Exact chemical name, concentration, additives and contamination | Determines whether CSM is suitable and what aging test is required. |
| Exposure type | Outdoor, indoor, splash, intermittent contact, continuous immersion or vapor | Changes chemical, weathering and permeation risk. |
| Temperature | Minimum, continuous maximum, peak maximum and peak duration | Controls flexibility, aging, compression set and bond durability. |
| Mechanical duty | Static compression, flexing, folding, pressure, abrasion, tension or movement | Changes hardness, reinforcement, thickness and test method. |
| Material target | Customer compound or grade if fixed; otherwise required hardness, color and properties | Separates mandatory requirements from supplier formulation choices. |
| Weathering limits | UV or outdoor duration, ozone condition, color change and cracking criteria | Turns “weather resistant” into a measurable acceptance requirement. |
| Tolerances | Critical dimensions, thickness, coating, seam and inspection method | Controls tooling, process capability and measurement cost. |
| Compliance / flame | Exact regulation, rating, approval, report or customer standard | Prevents a generic CSM name from being mistaken for compliance. |
| Testing | Material aging, chemical immersion, adhesion, leak, weathering or functional test | Allows validation scope, cost and timing to be reviewed before production. |
| Quantity | Prototype quantity, order quantity and annual demand | Influences tooling, process, material form and manufacturing route. |
| Packaging / traceability | Label, lot, cleanliness, roll or part packaging requirements | Ensures delivery format matches receiving, storage and production needs. |
CSM FAQ
Frequently Asked Questions About CSM Rubber
These answers are material-family guidance. Final performance should always be confirmed against the exact CSM compound, product construction and service conditions.
What does CSM stand for in rubber materials?
CSM stands for chlorosulfonated polyethylene. It is the standardized abbreviation for this specialty synthetic rubber family, not a complete compound or finished-part specification.
Is CSM the same as Hypalon?
Hypalon® was a trade name historically associated with chlorosulfonated polyethylene products. In current purchasing, use CSM or the exact approved material designation rather than assuming that any product described colloquially as Hypalon has the same grade, formulation or construction.
Are CSM and CSPE the same?
Both abbreviations are used for chlorosulfonated polyethylene. CSM is the standardized rubber abbreviation, while CSPE is also common in technical and coated-fabric contexts. The exact polymer grade and compound still need confirmation.
Is CSM resistant to ozone and outdoor weather?
Yes. Ozone, sunlight, oxidation and weathering resistance are major CSM strengths. The actual exposure duration, strain, color change, temperature and finished-product construction should still be included in validation.
What temperature can CSM rubber withstand?
There is no universal range. One commercial CSM sheeting family publishes approximately -35°C to +125°C, but other compounds and constructions differ. Confirm low-temperature function, continuous heat, peak duration and chemical exposure against the selected material.
Is CSM chemically resistant?
CSM is useful with many acids and inorganic chemicals, but it is not universally chemical resistant. Chemical identity, concentration, oxidizing strength, temperature, exposure time and compound formulation determine suitability.
Can CSM be used with oil or fuel?
CSM can provide fair or useful resistance to selected oils and greases, but published guidance varies by compound and fluid. It should not replace NBR or FKM automatically in oil or fuel service; exact-fluid testing is important.
Is CSM suitable for acids and alkalis?
CSM is often a strong candidate for dilute acids, many inorganic chemicals and selected alkalis. Concentrated oxidizing acids and incompatible solvents require particular caution, and hot immersion should be validated.
Is all CSM rubber flame resistant or self-extinguishing?
No. Some CSM compounds are formulated and marketed for flame resistance or self-extinguishing behavior, but the exact standard, specimen construction, thickness and test result must be confirmed. Polymer name alone is not a flame rating.
CSM or EPDM: which is better?
Both provide strong outdoor and ozone resistance. EPDM is often the economical starting point for water, steam and glycol service, while CSM is considered when outdoor durability must be combined with selected chemical, coating or flame-performance requirements.
CSM or neoprene rubber: which should I choose?
CSM generally provides stronger long-term weathering, oxidation and acid resistance. CR, commonly called neoprene, offers a useful balance of weathering, mechanical performance and moderate oil resistance. Compare the exact chemical, temperature, flexing and cost requirements.
Can CSM rubber be made in colors other than black?
CSM can be compounded in selected colors, but availability, color tolerance, UV exposure, staining, filler system and minimum production quantity must be confirmed for the chosen compound.
Can CSM be bonded to fabric or metal?
Yes. CSM is used in coated fabrics and can be included in rubber-to-substrate bonded components when surface preparation, fabric treatment, adhesive, compound and cure process are designed together. Specify the relevant adhesion and aging test.
Does CSM automatically meet FDA, drinking-water or RoHS requirements?
No. CSM is not automatically approved for food contact, drinking water, environmental compliance or any customer standard. The exact compound, application, test scope and documentation must be confirmed before approval.
What information is needed to quote a custom CSM part?
Send the drawing, 3D model or physical sample together with the product construction, exact chemicals, outdoor exposure, minimum and maximum temperature, movement, hardness, color, tolerance, compliance, testing and quantity requirements.
Custom CSM Components
Have a CSM gasket, protective part, profile or coated component to develop?
Send the available drawing or sample information together with the exact chemical, outdoor exposure, temperature, product construction, hardness target and expected quantity. We can review the CSM material direction, manufacturing feasibility and the technical information still needed before quotation.
