PPA – Polyphthalamide PPA GF50
AKROMID® T5 GF 50 6 black (6331)
AKROMID® T5 GF 50 6 black (6331) is a 50% glass fibre reinforced, inorganic high heat stabilised polyphthalamide with very high stiffness and strength.
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.
