Preliminary datasheet

PARA – Polyaramide PARA GF 35 FR (40)

AKROLOY® PARA GF 35 FR black (7496)

AKROLOY PARA GF 35 FR black (7496) is a flame-retarded, 35% glass-fiber reinforced Polyarylamide with very high flow, highest modulus and strength and low creep. Small water-absorption and very small change of properties due to water-absorption.

Typical applications

Components in Electrical Industry 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.
