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 or carbon fiber 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 STANDARD GRADES 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 above).
TECAPEEK GF30 (30% Glass Filled)
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.
TECAPEEK CF30 (30% Carbon Filled)
TecaPEEK ® CF30 material contains 30% carbon fibers, providing the ultimate in tensile and flexural modulus (stiffness), with excellent properties up to 600°F (315°C), while increasing the material's thermal and electrical conductivity. Carbon-filled TecaPEEK is available in pre-molded sheet, solid round rod and thick-walled cylindrical tube shapes and is black in color.
TECAPEEK PVX (bearing grade)
This bearing grade TecaPEEK ® includes low friction additives reducing the coefficient of friction and increasing wear resistance. TECAPEEK PVX is intended for bearing and wear applications of all kinds. TecaPEEK PVX is available in pre-molded sheet, solid round rod and thick-walled cylindrical tube shapes and is black in color.
