95 kJ/m²

AKROMID® B28 GF 33 1 GIT black (6846) is a 33% glass fibre reinforced, heat stabilised, easy flowing polyamide 6 with very high stiffness and strength for gas injection technology.

Typical applications

Engineering parts, which are produced by gas injection technology. Furthermore B28 GF 33 1 GIT black (6846) can be used for standard injection moulding for demanding surface quality.

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.
