PARA – Polyaramide PARA GF 35 FR (40)
AKROLOY® PARA GF 35 FR black (7496)
AKROLOY PARA GF 35 FR black (7496) is a halogen free 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.
Components in Electrical Industry which need low creep even in conditioned state.
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.
