PA6.6 – Polyamide 6.6 PA66 GF15 + GB15
AKROMID® A3 GM 15/15 black (1073)
AKROMID® A3 GM 15/15 black (1073) is a 15% glass fibre reinforced, 15% glass bead filled polyamide 6.6 with good surface and low warpage.
Components in mechanical enginneering and automotive industry with high surface requirements
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.
