PA6.6 – Polyamide 6.6 PA66-I GF20 + GB10
AKROMID® A3 GM 20/10 S1 natural (1217)AKROMID® A3 GM 20/10 S1 natural (1217) is a 20% glass fiber and 10% glass beads reinforced, impact modified PA 6.6. It is characterised by a medium cold impact strength as well as good adhesion properties. Furthermore, the material impresses with a good surface appearance and low warpage and is therefore perfectly suitable for technical demanding components in the mechanical engineering and automotive industry. It has a light inherent color.

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.
