AKROMID® A3 ICF 40 black (5116) is a 40% carbon fibre reinforced polyamide 6.6 with high flexural strength and good sliding properties

Typical applications

Mechanically high stressed parts in all industries

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.
