Reliable custom rubber parts for industrial applications

Quick Answer

Red silicone rubber strip measuring 0.85 mm thick and 40 mm wide, specified in RAL 3002 Carmine Red. Supplied length, Shore A hardness, compound grade, tolerances, surface finish, cut format, and packaging can be confirmed for application-specific sealing, cushioning, separation, or protection.

Red Silicone Rubber Strip 0.85mm x 40mm, RAL 3002 Carmine Red

A precision-extruded red silicone rubber strip measuring 0.85mm in thickness and 40mm in width, color-matched to RAL 3002 Carmine Red, engineered for thin-profile sealing, gasketing, and insulation applications requiring consistent dimensional accuracy and verified mechanical performance.

Product Overview

This silicone rubber strip is manufactured through continuous extrusion using formula code 0509EDr, producing a uniform flat cross-section with tight control over both thickness and width. Each production run undergoes batch testing to verify physical properties against established tolerance ranges, ensuring consistent quality across large-volume orders. The strip’s carmine red coloration is matched to the RAL 3002 standard, a deep, intense red widely used in industrial applications where consistent, verifiable color identification matters.

Color Standard: RAL 3002 Carmine Red

The strip’s color is formally matched to RAL 3002, officially designated Carmine Red within the RAL Classic color system, a deep and intense red tone commonly selected for its strong visual identity and consistent industrial reproducibility. This RAL designation allows manufacturers, buyers, and quality control teams to verify color accuracy against a recognized international standard rather than relying on subjective visual comparison alone. Specifying RAL 3002 ensures that repeat production batches maintain consistent coloration across different manufacturing runs and even across different suppliers.

Mechanical Performance Highlights

  • Hardness holds tightly at 44.8 Shore A average, falling within the 45.0 plus or minus 1.0 target range required for consistent flexibility and sealing force.
  • Elongation at break of 512 percent demonstrates high stretchability, allowing the strip to accommodate movement and vibration without tearing.
  • Progressive modulus values at 50 percent, 100 percent, and 300 percent elongation confirm predictable stress response across increasing strain levels, supporting reliable performance in dynamic sealing applications.
  • Tensile strength of 11.55 N per square millimeter indicates solid resistance to pulling forces during installation and operational use.
  • Dimensional tolerances on both thickness (0.82 to 0.88mm) and width (39.5 to 40.2mm) are tightly controlled, supporting precision-fit applications where inconsistent stock thickness would compromise sealing performance.

Manufacturing and Quality Control

Every production batch is assigned a unique furnace number, formula code, and batch number, enabling full traceability from raw material formulation through final testing. Test results are recorded against a defined tolerance range and cross-referenced to internationally recognized testing standards, specifically ASTM D2240 for hardness and ASTM D412 for tensile strength, elongation, and modulus properties. This structured quality documentation allows buyers to verify that each shipped batch meets the same performance benchmarks regardless of production date, supporting long-term supply consistency for repeat orders.

Common Applications

  • Thin-profile gasket sealing for enclosures, panels, and equipment housings where minimal clearance is available and consistent thickness is critical.
  • Vibration dampening and cushioning strips positioned between rigid components in mechanical or electronic assemblies.
  • Color-coded identification strips in industrial settings where RAL-matched red signals a specific function, warning, or product line.
  • Automotive, appliance, and HVAC sealing applications requiring flexible, heat-tolerant strip material with verified mechanical properties.
  • General industrial masking, edge protection, or spacer applications benefiting from high elongation and stable modulus performance under repeated flexing.

Frequently Asked Questions

What are the confirmed dimensions of this red silicone strip?

The confirmed cross-section is 0.85 mm thick and 40 mm wide. The supplied length, cut-length options, dimensional tolerances, and edge requirements have not been specified and are available upon request. These details should be confirmed according to the installation method, order quantity, and required delivery format.

What color is the silicone rubber strip?

The specified color is RAL 3002 Carmine Red. If precise visual matching is required, the color reference, permitted variation, surface finish, lighting conditions, and inspection method should be agreed upon before sampling. A physical reference may be used to support color evaluation when necessary.

What Shore A hardness is available?

The Shore A hardness has not been specified. Selection depends on the required flexibility, compression behavior, handling, installation geometry, strip thickness, and operating conditions. The required hardness and exact silicone compound should be confirmed before sample development or production.

Can the thickness, width, or length be customized?

Custom thickness, width, supplied length, and cut length can be evaluated from a drawing, physical sample, or verified specification. Manufacturing feasibility, tolerances, tooling, MOQ, and lead time depend on the requested dimensions, silicone compound, hardness, surface requirements, packaging, and order quantity.

Can adhesive backing be added to the silicone strip?

Adhesive backing has not been specified for this product. Its feasibility depends on the silicone surface, adhesive system, contacted substrate, operating temperature, environmental exposure, installation method, and required bond performance. Complete bonding requirements should be provided for technical evaluation and application-specific testing.

Are samples available for dimensional and application testing?

Sample availability is confirmed after reviewing the required length, silicone compound, hardness, tolerances, color criteria, surface finish, packaging, and quantity. Samples should be evaluated for dimensions, appearance, fit, handling, compression, material compatibility, and functional performance under the intended operating conditions.

Request Product Evaluation

Provide the required strip length, drawing or sample, silicone compound, Shore A hardness, dimensional tolerances, application conditions, quantity, and estimated annual volume. Please also identify any surface, color-matching, inspection, compliance, or packaging requirements. Manufacturing feasibility, samples, tooling, MOQ, lead time, and commercial terms can then be evaluated.
