AKROMID®
T9 black (8380)PPA-I
AKROMID® T9 black (8380) is an unreinforced, modified polyphthalamide with medium stiffness and strength, as well as high chemical resistance. This grade has a reduced lubrication package optimized for extrusion applications. The compound is based on PA9T and has lower moisture uptake than conventional PA6T variants. This leads to a significantly higher consistency of the glass transition temperature and higher strength at elevated temperatures especially in conditioned state.
