AKROMID®

A3 1 S3 black (2768)PA66+PA6-I

AKROMID® A3 1 S3 black (2768) is an unreinforced, impact modified polyamide 6.6/6 blend. It is characterised by a medium dry impact strength. 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.
