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

    "Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
