Preliminary datasheet

PEEK – Polyetheretherketone PEEK CF10

AKROTEK® PEEK CF 10 TM black (7759)

AKROTEK® PEEK CF 10 TM black (7759) is a 10% carbon fibre reinforced medium viscosity polyetheretherketone with high flexural strength and good sliding properties as well as good tribological properties

Typical applications

Elements in the automotive-, aeronautical-, industrial- and medical engineering that require high strength and high stiffness in a temperature environment above 150°C.

Processing information

The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
