Technical Data

 

Product Description

 

Unitrex PEEK is a semi-crystalline high temperature thermoplastic that offers design engineers a truly unique combination of exceptional performance characteristics. When compared with other engineering polymers, this material ranks as the best or nearly the best in every performance category. Unitrex PEEK has a relative thermal index of 480°F and has a UL 94 flammability rating of V-0, with very low levels of smoke generation and toxic gas emission. Additionally, this material exhibits excellent electrical properties, which remain stable over a wide range of both temperatures and frequencies.

 

Unitrex PEEK is chemically resistant to a wide range of organic and inorganic liquids and is insoluble in all common solvents. In addition, it is unaffected by steam and hot water and has a very low moisture absorption rate. This material offers superior dimensional stability and machines easily. While unfilled Unitrex PEEK offers good wear resistance, Unitrex L has been reinforced with graphite and PTFE to provide an ideal combination of low friction and enhanced wear. For applications that require improved strength and stiffness, a 30% glass fiber filled grade is available (Unitrex Rg-30). Unfilled Unitrex PEEK stock shapes are light beige in color and are available from Nytef Plastics in a full range of heavy gauge rod, plate and tubular bar sizes.
