AKROMID®

T5 GF 50 black (6247)PPA GF50

AKROMID® T5 GF 50 black (6247) is a 50% glass fibre reinforced polyphthalamide. It is characterised by its very high stiffness and strength, even at elevated temperatures up to 120°C. Due to its low moisture absorption, the mechanical properties remain nearly unchanged even in conditioned state. Not only the good creep resistance, but also the hydrolysis and chemical resistance complement the property profile and make it the material of your choice for under the hood applications and connectors with special strength requirements.
