GENERAL DESCRIPTIONTECAPEEK ® 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 ® (unfilled)
Unfilled TECAPEEK ® is the general purpose grade that is unreinforced and offers the highest elongation and toughness of all PEEK grades. Unfilled TecaPEEK is available in pre-molded sheet, solid round rod and thick-walled cylindrical tube shapes and is natural (a very light brown or tan) in color (see photo).
