Preliminary datasheet

PEEK – Polyetheretherketone PEEK

AKROTEK® PEEK TM natural (5069)

3200 MPa

105 kJ/m²

AKROTEK® PEEK TM natural (5069) is an unreinforced polyetheretherketone with good tribological properties

Typical applications

Elements in the automotive-, aeronautical-, industrial- and medical engineering that require low friction and wear values 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.
