PA6.6 – Polyamide 6.6 PA66+PA6I/6T GF40
AKROLOY® PA GF 40 natural (6413)
AKROLOY® PA GF 40 natural (6413) is a 40% glass fibre reinforced, semi-aromatic polyamide blend with very high stiffness and strength, even in conditioned state.
Components with high dimensional stability, independent from moisture content. AKROLOY® PA GF 40 is an alternative for aluminium- and zinc diecast alloys.
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.
