Preliminary datasheet

PA6.6 – Polyamide 6.6 PA66 + PA6I/6T GF50

AKROLOY® PA GF 50 natural (7573)

AKROLOY® PA GF 50 natural (7573) is a 50% glass fibre reinforced, semi-aromatic polyamide blend with very high stiffness and strength, even in conditioned state.

This product is especially equipped for high laser transparency for laser welding.

Typical applications

Components with high dimensional stability, independent from moisture content. AKROLOY® PA GF 50 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.
