PA6.6 – Polyamide 6.6 PA66-I

AKROMID® A3 1 S3 black (21002)

2300 MPa

n.b.

AKROMID® A3 1 S3 black (21002) is an unreinforced, heat stabilised, medium dry impact resistant polyamide 6.6.

Typical applications

Connecting and fixing systems, used are elevated temperatures in the automotive and electro industry

Processing information

The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
