T9 GF 30 grey (8134)PPA GF30

AKROMID® T9 GF 30 grey (8134) is a 30% glass fiber reinforced polyphthalamide colored in grey, similar to RAL 7047. Not only is it characterised by very high stiffness and strength, but also by its high temperature and chemical resistance. Based on PA9T, the material has a lower moisture absorption and a Tg which is more constant compared to conventional PA6T variants. Therefore, it is perfectly suitable for parts with tight dimensional tolerances which are exposed to high mechanical loads.
