PA6 – Polyamide 6 PA6 GF50
AKROMID® B28 GF 50 1 GIT black (4732)
AKROMID® B28 GF 50 1 GIT black (4732) is a 50% glass fibre reinforced, heat stabilised, easy flowing polyamide 6 with very high stiffness and strength for gas injection technology.
Engineering parts, which are produced by gas injection technology. Furthermore B28 GF 50 1 GIT black (4732) can be used for standard injection moulding for demanding surface quality.
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.
