PARA – Polyaramide PARA GF50
AKROLOY® PARA GF 50 1 black (7583)
AKROLOY® PARA GF 50 1 black (7583) is a 50% glass fibre reinforced polyarylamid with very high stiffness and strength, even in conditioned state.
Typical applications
Components with high dimensional stability, independent from moisture content. AKROLOY® PARA GF 50 is an alternative for aluminium- and zinc diecast alloys.
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.
