PA6.6 – Polyamide 6.6 PA66 + PA6I/6T CF40
AKROLOY® PA CF 40 1 black (8504)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.

Processing information
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.
