PA6.9 – Polyamide 6.9 PA6.9 GF20 FR(30)

AKROMID® NEXT G3 K8 9 FR LA white (8261)

AKROMID® G3 K8 9 FR LA white (8261) is a 20% glass fiber reinforced and flame-retardant PA 6.9 with medium strength and stiffness. The material is based on a flame-retardant system that is free of red phosphorus and halogens and meets the requirements according to UL94 V2 @ 0.8mm. The partially bio-based grade is characterised by particularly low moisture absorption and high chemical resistance compared to classic PA 6 and PA 6.6. This grade is colored in white similar to RAL 9010 and laser-markable with a dark color change. It is suitable for E&E applications such as busbar carrier due to its high CTI and GWFI.
