AKROLOY® PA ICF 40 black (5270) is a 40% carbon fibre reinforced, semi-aromatic polyamide blend with high stiffness, good sliding properties and reduced moisture.

Typical applications

Mechanically high stressed parts with dimensional stability and moisture independent properties

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.
