PA6 – Polyamide 6 PA6-I GF40
AKROMID® B3 GF 40 S1 LA black (7614)AKROMID® B3 GF 40 S1 LA black (7614) is a 40% glass fiber reinforced, impact modified Polyamide 6. It is characterised by a medium impact strength as well as a high stiffness and strength. Furthermore, the material impresses with its laser markability along with very good surface properties and is therefore perfectly suitable for housings and covers in the automotive industry with high demands on the surface.

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.
