AKROMID®

B3 GF 50 4 RM-M black (3221)PA6+X GF50

AKROMID® B3 GF 50 4 RM-M black (3221) is a 50% glass fiber reinforced polyamide 6, which is distinguished by outstanding surface properties even though its high glass fiber content. Due to its lower moisture uptake, the material is characterised by less mechanical changes in the conditioned state. Furthermore, it is chemically stabilised and therefore perfectly suitable for components in the automotive industry with demands for high resistance against CaCl2 solvents.
