OVERVIEW
Farrprene EU502A is a versatile medium-hardness compound for general-purpose flexible parts and two-shot overmoulding. Supplied as a translucent unfilled 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 0.900. Its low melt flow (MFI 1.3 g/10 min at 190°C/5 kg) provides the melt strength needed for stable profile and sheet extrusion. Heat Stabilized · Silky Touch.
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 3.6 g/10 min (230°C/5 kg) it sits at the stiffer end of the extrusion range, holding profile geometry well between the die and the cooling line. Its specific gravity of 0.900 is typical of an unfilled compound, which gives more parts per kilogram and the cleanest colour reproduction.

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
- Suited to profile, sheet and tube extrusion lines with conventional single-screw setups.
- Unfilled formulation for the cleanest surface finish and colourability.
- Heat-stabilised: the additive package is intended to limit degradation during processing and repeated re-melting of regrind.
- Silky-touch surface: formulated for a low-friction, non-tacky feel on visible and hand-contact surfaces.
- 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.
