PPA – Polyphthalamide PPA GF40

AKROMID® T5 GF 40 8 black (7963)

AKROMID® T5 GF 40 8 black (7963) is a 40% glass fibre reinforced polyphthalamide with very high rigidity and strength, as well as high temperature and chemical resistance.

This aromatic PPA keeps mechanical performance even at elevated temperatures as well as moisture pic-up. The material corresponds to the European food guideline EU 10/2011 and to the American FDA 21 CFR. This grade is suitable for parts of kitchen and household appliances.
