PA6.6 – Polyamide 6.6 PA66 GF50

AKROMID® A3 GF 50 HU grey (6601)

AKROMID® A3 GF 50 HU grey (6601) is a 50% glass fiber reinforced polyamide 6.6 in grey (similiar to RAL 7035). 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, in the automotive industry or for household appliances. The material is listed at UL in all colors.
