PPA – Polyphthalamide PPA GF35
AKROMID® T5 GF 35 4 black (7692)
AKROMID® T5 GF 35 4 black (7692) is a 35% glass fibre reinforced polyphthalamide with high rigidity and strength, as well as high temperature and chemical resistance.
Applications are parts with tight dimensional tolerances even under high mechanical load.
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.
