GENERAL DESCRIPTION
TECAPEEK ® is a unique semi-crystalline, high temperature engineering thermoplastic based upon the PolyEtherEtherKetone (PEEK) or PolyArylEtherKetone (PAEK) polymers. It is an excellent material for a wide spectrum of applications where mechanical, thermal, and chemicaln 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 (TECAPEEK GF30) or carbon fiber (TECAPEEK CF30) reinforcements enhances the mechanical and thermal properties of the basic TecaPEEK ® material. A self-lubricated grade, TECAPEEK PVX is also manufactured for low friction and increased wear resistance in bearing applications.
TecaPEEK ® is produced only by Ensinger Industries and is available in sheet/plate, solid round rod, and rigid tube forms for machining into parts.
TECAPEEK ® GF30
The addition of 30% glass fibers gives TecaPEEK ® GF30 material increased mechanical performance and stiffness at temperatures up to 600°F (315°C), while reducing it's coefficient of thermal expansion. Glass-filled TecaPEEK is available in pre-molded sheet, solid round rod and thick-walled cylindrical tube shapes and is light brown or tan in color.
