| About |
|---|
| Epalex 7517 UV3 SAS is a thermoplastic rubber modified mineral filled polypropylene compound. It is a very high flow injection moulding grade developed for parts with long flow lengths and high impact strength at sub-zero temperatures whilst maintaining good rigidity at high ambient temperatures. The material displays minimal shrinkage and low CLTE. It contains an antistatic agent and mould release and is stabilized for continuous outdoor weathering.&& |
