PPA – Polyphthalamide PPA GF40

AKROMID® T5 GF 40 black (6486)

High Performance grade

AKROMID® T5 GF 40 black (6486) is a 40% glass fibre reinforced polyphthalamide with heat stabilization, very high rigidity and strength, as well as high temperature and chemical resistance.

This aromatic PPA keeps mechanical performance even at elevated temperatures or moisture pic-up
