PPA – Polyphthalamide PPA GF40
AKROMID® T5 GF 40 4 black (7585)
AKROMID® T5 GF 40 black (7585) is a 40% glass fibre reinforced polyphthalamide with anorganic heat stabilization, very high rigidity and strength, designed for hydrolysis resistance.
This aromatic PPA keeps mechanical performance even at elevated temperatures or moisture pic-up
Heavy duty components in the automotive cooling circuit or other dimensionally stable and rigid parts for engineered applications in the automotive or electrical industry requiring strength and durability even at high temperatures or moist conditions.
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.
