PEEK – Polyether ether ketone PEEK GF30
AKROTEK® PEEK GF 30 nature (5047)
AKROTEK® PEEK GF 30 natural (5047) is a 30% glass fibre reinforced polyetheretherketone with high stiffness and strength.
Elements in the automotive-, aeronautical-, industrial- and medical engineering that require high strength in a temperature environment above 150°C.
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.
