Preliminary

A3 1 S3 black (11392)

PA66-I

AKROMID® A3 1 S3 black (11392) is an unreinforced, impact modified Polyamide 66. It is characterised by a medium dry impact strength whilst maintaining good flowability and low emission. 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 electronic industry. Its good flowability qualifies the material for processing in multi-cavity moulds. It was developed as successor of AKROMID® A3 1 S3 black (1139) to meet the stringent demand concerning emission values of automotive interior applications.
