OVERVIEW
Farrprene EF653AU is a versatile medium-hardness compound for general-purpose flexible parts and two-shot overmoulding. 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 7.5 MPa, elongation at break of >800%, and a specific gravity of 1.22. A balanced melt flow (MFI 4.4 g/10 min at 190°C) suits a wide processing window. UV Stabilized · Heat Stabilized · Silky Touch.

TYPICAL APPLICATIONS
- Two-shot overmoulding onto PP/PE and rigid substrates
- General-purpose seals, grips and flexible housings
- Cable jacketing and strain reliefs
- Automotive interior trim, NVH and sealing components
