TECAPEEK unfilled PEEK
TECAPEEK PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining, and is extruded in sheet, rod and tube using Victrex® PEEK polymer. Well known for its high temperature resistance, PEEK is a unique semi-crystalline, engineering thermoplastic that also offers excellent chemical compatibility. Parts manufactured from high temperature plastic PEEK polymer can operate at temperatures up to 260°C (480°F) and has a melting point around 341°C (646°F). PEEK plastic is often used in hot water or steam environments while maintaining physical properties such as flexural and tensile strength on a high level. Polyetheretherketone is often viewed as one of the engineering thermoplastics that tends to command a high price, however experienced users have come to realize the added value that PEEK materials bring, by offering the possibility of manufacturing parts that are lighter, stronger and able to survive longer in harsh environments.
- 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.
