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

AKROLOY® PA GF 50 8 black (6732)

17500 MPa

260 MPa

105 kJ/m²

AKROLOY® PA GF 50 8 black (6732) is a 50% glass fibre reinforced, semi-aromatic polyamide blend with very high stiffness and strength, as well as reduced moisture absorption.

Please note that the material does not fulfill the requirements according to ACS and NSF61 anymore.

Typical applications

Components with tight dimensional tolerances even under high mechanical load. It is a very cost effective alternative for zinc- and aluminium 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.
