Dryflex Thermoplastic Vulcanisates (TPV)

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.

Our aim is to supply a material that precisely matches application requirements. We are constantly testing new polymers, additives, stabilisers and other ingredients to create unique material combinations. We have engineered several Dryflex TPV series to suit different applications, with properties including flow characteristics, hardness, specific gravity, strength resistance and colour.

The Dryflex TPV range offers:

  • A wide range of hardness’
  • Grades that can be processed by injection moulding, extrusion, blow moulding and thermoforming
  • Service temperatures of -60°C to 135°C
  • Improved resistance to aggressive fluids such as oils, acids, bases and aqueous solutions
  • 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
