AKROMID®

A3 GF 50 1 natural (1259)

PA66 GF50

AKROMID® A3 GF 50 1 natural (1259) is a 50% glass fiber reinforced polyamide 6.6. 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. gearbox components. The material has a light inherent color.
