PA6.6 – Polyamide 6.6 PA66+PA6I/6T-I
AKROLOY® PA GF 35 S1 black (7121)
AKROLOY® PA GF 35 S1 black (7121) is a 35% glass fibre reinforced, cold impact strength, semi-aromatic polyamide blend with high stiffness and strength, even in conditioned state.
Components with high dimensional stablilty and high strength and stiffness, barely effected by moisture absorption.
The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
