PA6.6 – Polyamide 6.6 PA66-I
AKROMID® A3 1 S3 black (21002)
AKROMID® A3 1 S3 black (21002) is an unreinforced, heat stabilised, medium dry impact resistant polyamide 6.6.
Connecting and fixing systems, used are elevated temperatures in the automotive and electro industry
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.
