PA6.6 – Polyamide 6.6 PA66 GF50
AKROMID® A28 GF 50 1 GIT black (5029)
AKROMID® A28 GF 50 1 GIT black (5029) is a 50% glass fibre reinforced, heat stabilised, easy flowing polyamide 6.6 with very high stiffness and strength, for gas injection technology
Engineering parts, which are produced by gas injection technology. Furthermore AKROMID® A28 GF 50 1 GIT black (5029) 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.
