Description

Thermoplastic Vulcanisate (TPV) compounds are high performance materials designed for demanding applications where improved durability, heat or fluid resistance are required. They are composed of a highly vulcanised rubber phase dispersed throughout a thermoplastic matrix and combine the processing ease, efficiency and recyclability of a thermoplastic with the improved flexibility, low compression set and resistance to aggressive fluids of a vulcanised rubber. They have seen strong growth in automotive seals, pipe seals, and other applications where a heat resistance of up to 135°C is required. Hardness values range typically from 45 Shore A to 50 Shore D. TPVs also lend themselves to underbonnet automotive applications where improved temperature and oil resistance is required. The main features are:


  • Service temperatures of -60°C to 135°C
  • Low compression set
  • Low flex fatigue
  • The Dryflex XL grades are easier to colour
  • Lightweight parts
  • Design flexibility
  • Recyclability
  • Excellent weathering and environmental resistance
  • Adhesion to PP and PE in multi-component applications
