B28 GF 35 FR EN natural (8388)PA6 GF35 FR(44)

AKROMID® B28 GF 35 FR EN natural (8388) is a flame retardant PA6 with 35% glass fibres. The flame retardant system is free of red phosphorus and halogens, leading to optimised electrical properties for e-mobility applications. Due to formulation and production measures, electrical neutrality with regard to halogen compounds < 10 ppm for bromine + iodine can be guaranteed. Due to its very good flowability, it is characterised by easy processability as well as good surface properties. The material has excellent long-term heat stability and outstanding mechanical properties. This product is subject to an increased testing effort.
