AKROMID®

A3 1 S3 black (1139)PA66-I

AKROMID® A3 1 S3 black (1139) is an unreinforced, impact modified Polyamide 6.6. It is characterised by a medium dry impact strength whilst maintaining good flowability. Furthermore, the material is heat stabilised and therefore perfectly suitable for connecting and fixing systems which are used at elevated temperatures in the automotive and electro industry. Its good flowability qualifies the material for processing in multi-cavity moulds. For new projects, please consider our successor grade A3 1 S3 schwarz (11392).
