Preliminary

PA CF 40 1 black (8504)PA66+PA6I/6T CF40

AKROLOY® PA CF 40 1 black (8504) is a 40% carbon fiber reinforced, semi-aromatic polyamide blend. It is characterised by very high stiffness and impact strength even in conditioned state. Furthermore, it convinces through very good weld line strength. It is therefore perfectly suitable for mechanically high stressed parts, for example in sports and leisure with demanding requirements for dimensional stability.
