PA6.9 – Polyamide 6.9 PA6.9 GF30
AKROMID® NEXT G3 GF 30 1 natural (8085)The partly bio-based AKROMID® NEXT G3 GF 30 1 natural (8085) has an increased chemical resistance and a lower moisture absorption compared to the classic PA 6 and PA 6.6. This heat stabilised and 30% glass fibre reinforced PA 6.9 is suitable for components with high demands on strength and stiffness.

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.
