AKROLOY® PA GF 60 black (6418) is a 60% glass fibre reinforced, semi-aromatic polyamide-blend with very high stiffness and strength, even in conditioned state.

Typical applications

Components with high dimensional stability, independent from moisture content. AKROLOY PA GF 60 black is an alternative for aluminium- and zinc diecast alloys.

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.
