OVERVIEW
Farrprene IF350A is a soft, highly flexible compound for seals, grips and tactile overmoulds. 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 3.5 MPa, elongation at break of >800%, and a specific gravity of 1.190. Its high melt flow (MFI 30 g/10 min at 190°C/5 kg) fills thin-wall and complex injection geometries with short cycle times. Heat Stabilized.
This is a SEBS-based compound. SEBS is the hydrogenated form of SBS: removing the double bonds from the mid-block gives it substantially better resistance to UV, heat and oxidation, which is why it is the usual choice for parts that see sunlight, warm service or a long design life.
At 118 g/10 min (230°C/5 kg) it is a high-flow injection grade, suited to thin walls, long flow paths and short cycles. Its specific gravity of 1.190 reflects the mineral filler loading, which is what buys the dimensional stability and cost position of a filled grade.

TYPICAL APPLICATIONS
- Flexible seals, gaskets and bellows
- Soft-touch overmoulds and tactile grips
- Flexible tubing and protective profiles
- Automotive interior trim, NVH and sealing components
- Household goods, handles and seals
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.
- Heat-stabilised: the additive package is intended to limit degradation during processing and repeated re-melting of regrind.
- SEBS-based: the hydrogenated backbone gives better UV, thermal and oxidative stability than an SBS compound.
- Colour-matchable and re-processable - production scrap can be re-melted and reused.
