HZD8250 TPV
Extrusion-grade thermoplastic vulcanizate (TPV) for cable jackets and seals
Overview
HZD8250 is an extrusion-grade thermoplastic vulcanizate (TPV) with a 75 Shore A hardness. It offers excellent extrusion behaviour, compression set recovery, slip and abrasion resistance, and strong colourability, while meeting RoHS, REACH and halogen-free requirements. Easy to process and recyclable, it is used for cable over-sheathing and door / window sealing strips.
Key features
- Excellent extrusion performance
- Outstanding compression set recovery
- Slip and abrasion resistance, multi-colour
- Easy to process and recyclable
- RoHS, REACH and halogen-free compliant
