PA6.6 – Polyamide 6.6 PA66 GF20 + GB10
AKROMID® A3 GM 20/10 4 WIT black (4529)AKROMID® A3 GM 20/10 4 WIT black (4529) is a 20% glass fiber and 10% glass bead reinforced polyamide 6.6. It is characterized by high rigidity and strength. The material also convinces with a good surface and low tendency to warp and can be processed using a water injection process. In addition, the material is stabilized against hydrolysis and chemicals and is therefore ideally suited, for example, for technical components in the cooling water circuit 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.
