PA6.6 – Polyamide 6.6 PA66 GF25

AKROMID® A3 GF 25 3 black (3094)

AKROMID® A3 GF 25 3 black (3094) is a 25% glass fibre reinforced, nucleated polyamide 6.6 with high stiffness and strength

Typical applications

Mainly components in mechanical engineering and 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.
