AKROMID® A3 GF 30 4 6 black (13690)

10000 MPa

200 MPa

85 kJ/m²

AKROMID® A3 GF 30 4 6 black (13690) is a 30% glass fibre reinforced, high heat stabilised, hydrolysis- and chemical resistant polyamide 6.6 with high stiffness and strength. It is the official DDPD-free successor of formulation 1369.

Typical applications

Functional parts in the heating- and cooling system in the automotive industry.

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.
