Preliminary datasheet

PEEK – Polyether ether ketone PEEK GF50

AKROTEK® PEEK GF 50 9 black (5183)

AKROTEK® PEEK GF 50 9 black (5183) is a 50% glass fibre reinforced process improved polyetheretherketone with very high stiffness and strength

Typical applications

Elements in the automotive-, aeronautical-, industrial- and medical engineering that require high strength 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.
