PARA – Polyarylamide PARA GF 35 FR (40)
AKROLOY® PARA GF 35 FR orange (8039)AKROLOY® PARA GF 35 FR orange (8039) is a flame retardant, 35% glass-fiber reinforced Polyarylamide with highest modulus and strength. The material is based on a flame retardant system that is free of red phosphorus and halogens and is colored in orange similar to RAL 2003. Due to its very good flowability, an improved surface quality is achieved. This grade is also suitable for applications in electrical industries, which need low creep even in conditioned state.
