Product Specifications

Technical details and manufacturing context for Extruded Rubber Profile

Definition

Extruded rubber profiles are continuous lengths of rubber formed by forcing uncured compound through a die, then vulcanizing to achieve final properties. They are used for sealing, gasketing, vibration damping, and edge protection in vehicles, windows, doors, and machinery. Profiles are specified by cross-section geometry, material grade (e.g., EPDM, NBR, silicone), hardness, and performance requirements such as temperature range and compression set. Grades differ by polymer type, filler content, and curing system, affecting durability, chemical resistance, and cost.

Working Principle

The profile works by deforming elastically under compression or bending, maintaining contact with mating surfaces to block passage of fluids, air, dust, or noise. Its cross-section shape determines how it distributes stress and recovers after deflection. Material elasticity and hardness govern the sealing force and long-term resilience.

Common Materials

EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Butadiene Rubber), Silicone (VMQ), Neoprene (CR), Natural Rubber (NR), TPE (Thermoplastic Elastomer)

Technical Parameters

Parameter	Typical range	Notes & selection driver
Cross-section dimensions	1–100 mm mm	Width and height of profile; custom shapes available.ISO 3302-1
Hardness (Shore A)	40–80 Shore A	Typical range; lower for soft seals, higher for structural support.ASTM D2240
Tensile strength	5–15 MPa	Varies with material; EPDM typically 7–12 MPa.ASTM D412
Elongation at break	200–600 %	Higher for flexible seals.ASTM D412
Compression set	≤30 %	After 22h at 70°C; lower is better for sealing.ASTM D395
Operating temperature range	-40 to +120 °C	EPDM typical; silicone can extend to -60 to +200°C.ASTM D2000
