PARA – Polyarylamide PARA FGF50

AKROLOY® PARA FGF 50 1 black (8186)

AKROLOY® PARA FGF 50 1 black (8186) is a 50% flat glass fiber reinforced polyarylamide. Due to the flat glass fiber, the material is characterised by significantly improved properties 90° to the flow direction as well as low warpage. Even in conditioned state, it impresses with very high stiffness and strength 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.
