PARA – Polyarylamide PARA GF60

AKROLOY® PARA GF 60 HU natural (8516)

AKROLOY® PARA GF 60 HU natural (8516) is a 60% glass fibre reinforced polyarylamid with very high stiffness and strength, even in conditioned state owing to its lower moisture uptake. Furthermore, the material shows very good flowability and surface properties. It is perfectly suitable for parts where dimensional stabilitiy is required. Besides, it can be used as an alternative for aluminium and zinc diecast alloys. The material is listed at UL in all colors.
