PA6 – Polyamide 6 PA6 GF50
AKROMID® B3 GF 50 1 black (20008)AKROMID® B3 GF 50 black (20008) is a 50% glass fiber reinforced polyamide 6. It is characterised by a very high stiffness and strength. Furthermore, the material is heat stabilised and therefore perfectly suitable for technical parts in industrial engineering and in the automotive industry, e.g. strut bearings.

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.
