Preliminary datasheet

PPA – Polyphthalamide PPA GF50

AKROMID® T5 GF 50 6 black (8000)

18500 MPa

260 MPa

65 kJ/m²

Standard Grade with good surface quality.

AKROMID® T5 GF 50 6 black (8000) is a 50% glass fibre reinforced polyphthalamide with anorganic heat stabilization, very high rigidity and strength, as well as high temperature and chemical resistance.

This aromatic PPA keeps mechanical performance even at elevated temperatures or moisture pic-up

Typical applications

Dimensionally stable and rigid parts for engineered automotive, industrial or electrical applications requiring strength and durability even at high temperatures or moist conditions.

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.
