PPA – Polyphthalamide PPA GF30

AKROMID® T1 GF 30 black (3466)

12500 MPa

215 MPa

60 kJ/m²

AKROMID® T1 GF 30 black (3466) is a 30% glass fibre reinforced polyphthalamide with very high rigidity and strength, as well as high temperature and chemical resistance. The material is electric friendly but with metal ions.

The product will be discontinued in 2019.

Typical applications

Parts with tight dimensional tolerances even under high mechanical load.

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.
