AKROMID®

A3 GM 20/10 S1 black (4817)PA66-I (GF20+GB10)

AKROMID® A3 GM 20/10 S1 black (4817) is a 20% glass fiber and 10% glass beads reinforced, impact modified PA 6.6. It is characterised by a medium cold impact strength as well as a good surface appearance and low warpage. It is therefore perfectly suitable for technical demanding components in the mechanical engineering and automotive industry.
