TECAPEEK® GF30 is Ensinger’s 30% glass fiber reinforced TECAPEEK product. Made with Victrex 450 GL30 PEEK polymer, it offers enhanced mechanical and thermal properties over those of our basic TECAPEEK offering. It also offers excellent resistance in harsh chemical environments and is electrically insulative.

  • Extremely high thermal and mechanical capabilities
  • Very high continuous working temperature
  • Very high heat deflection temperature
    For unreinforced TECAPEEK™, the HDT @264 psi is 152°C (306°F). The addition of 30% reinforcement results in a dramatic increase to 315°C (600°F).
  • Exceptional chemical resistance
    TECAPEEK™ GF30 is insoluble in all common solvents.
  • Very high level of dimensional stability
  • Good radiation resistance
    TECAPEEK™ GF30 exhibits superior resistance to high doses of gamma radiation.
  • Outstanding wear and abrasion resistance
  • Low smoke and toxic gas emissions
  • Excellent hydrolysis resistance
    TECAPEEK™ GF30 has an excellent resistance to hydrolysis in boiling water and superheated steam (sterilization/autoclavability) at temperatures in excess of 250°C (482°F).

TECAPEEK™s exceptional property profile enables it to be utilized in many of the most critical areas in general industry, as well as in the automotive, marine, nuclear, oil well, electronics, medical and aerospace fields.
