OVERVIEW
Farrprene EF456A is a soft, highly flexible compound for seals, grips and tactile overmoulds. 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 7 MPa, elongation at break of >800%, and a specific gravity of 1.00. Its low melt flow (MFI 1.4 g/10 min at 190°C) provides the melt strength needed for stable profile and sheet extrusion. Heat Stabilized.

TYPICAL APPLICATIONS
- Flexible seals, gaskets and bellows
- Soft-touch overmoulds and tactile grips
- Flexible tubing and protective profiles
- Construction profiles, gaskets and weatherstripping
- Automotive interior trim, NVH and sealing components
PROCESSING
