OVERVIEW
Farrprene EF820A is a firm, hard-wearing compound for structural flexible parts, seals and bushings. Supplied as a natural filled grade optimised for extrusion, it pairs the soft-touch feel of rubber with the clean, fast processing of a thermoplastic - no curing, fully re-meltable scrap.
The grade delivers a tensile strength of 10 MPa, elongation at break of >650%, and a specific gravity of 1.180. A balanced melt flow (MFI 5 g/10 min at 190°C) suits a wide processing window. Heat Stabilized · Silky Touch.

TYPICAL APPLICATIONS
- Structural flexible parts and snap-fit components
- Hard-wearing seals, bushings and grommets
- Profiles and trim requiring shape retention
- Consumer products, soft-touch overmoulds and grips
- Construction profiles, gaskets and weatherstripping
PROCESSING
- Suited to profile, sheet and tube extrusion lines with conventional single-screw setups.
- Filled formulation tuned for cost-efficiency and dimensional stability.
- Colour-matchable and re-processable - production scrap can be re-melted and reused.
