AKROMID® B3 GF 60 1 black (4644) is a 60% glass fibre reinforced, heat stabilised polyamide 6 with very high rigidity and strength

Typical applications

Components in mechanical engineering and in the automotive industry

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.
