OVERVIEW
Farrprene IF658A is a versatile medium-hardness compound for general-purpose flexible parts and two-shot overmoulding. Supplied as a natural filled grade optimised for injection-moulding, 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 5.5 MPa, elongation at break of >800%, and a specific gravity of 1.01. A balanced melt flow (MFI 5.0 g/10 min at 190°C) suits a wide processing window. SBS Based · Heat Stabilized.

Typical average values from a limited sample set; not a formal specification. Request the signed datasheet for current values.
TYPICAL APPLICATIONS
- Two-shot overmoulding onto PP/PE and rigid substrates
- General-purpose seals, grips and flexible housings
- Cable jacketing and strain reliefs
- Consumer products, soft-touch overmoulds and grips
- Automotive interior trim, NVH and sealing components
PROCESSING
- Runs on standard injection-moulding equipment; pre-drying is generally not required for unfilled grades.
- Filled formulation tuned for cost-efficiency and dimensional stability.
- Colour-matchable and re-processable - production scrap can be re-melted and reused.
