TECAPEEK® stock shapes are made exclusively with Victrex PEEK polymer. TECAPEEK is a unique, semi-crystalline, high temperature engineering thermoplastic. It is an excellent material for a wide spectrum of applications where thermal, chemical, and combustion properties are critical to performance. Especially significant in this regard is TECAPEEK's ability to retain its flexural and tensile properties at very high temperatures in excess of 250°C (482°F). The addition of glass fiber or carbon fiber reinforcements enhances the mechanical and thermal properties of the basic TECAPEEK® material.
- Excellent flexural, impact, and tensile characteristics
- 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™ is insoluble in all common solvents.
- A superior dielectric at high temperatures and frequencies
Good radiation resistance
TECAPEEK™ exhibits superior resistance to high doses of gamma radiation.
- Outstanding wear and abrasion resistance
- Low smoke and toxic gas emissions
Excellent hydrolysis resistance
TECAPEEK™ 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.
