VICTREX PEEK HT Is a semi-crystalline very high performance engineering thermoplastic for demanding applications.

VICTREX PEEK HT will give all the same performance advantages of standard VICTREX PEEK, such as chemical and wear resistance, high strength and toughness, with the additional performance advantages of:

  • Up to 3 times the wear resistance of standard VICTREX PEEK polymer at elevated temperature.
  • Physical properties, mechanical and compressive strength are retained for longer at elevated temperature, allowing higher loads at elevated temperature, without deformation of the component.
  • Enhanced long term resistance to creep.
  • Resistance to chemical attack, solvents, oils and fuels and hydrolysis.
  • Low flammability and smoke emission.
