PEEK(polyetheretherketone)
PEEK,
a unique semi-crystalline,
high-temperature engineering
thermoplastic, is an excellent
material for a wide spectrum of
applications where thermal,
chemical and combustion
properties are critical to
performance. Especially
significant in this regard is
PEEK's ability to retain it
flexural and tensile properties
at very high temperatures -- in
excess of 250° C (482° F).
The addition of glass fiber and
carbon fiber reinforcements
enhances the mechanical and
thermal properties of the basic
PEEK material.
