AKROMID®

A3 S3 natural (1176)PA66-I

AKROMID® A3 S3 natural (1176) is an unreinforced, dry impact modified Polyamide 6.6. The material is characterised by a very high impact strength and therefore perfectly suitable for connecting and fixing systems which are used in the automotive and electro industry and that are exposed to high loading speeds. The material has a light inherent color.
