Preliminary datasheet

PEEK – Polyetheretherketone PEEK M15

AKROTEK® PEEK M 15 8 black (7532)

AKROTEK® PEEK M 15 8 black (7532) is an 15% mineral-filled easy flowing polyetheretherketone with FDA compliant ingredients, very good surface and slight tendency to warp

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.
