PARA – Polyarylamide PARA GF 35 FR (40)
AKROLOY® PARA GF 35 FR black (7496)AKROLOY® PARA GF 35 FR black (7496) 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. 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.

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.
