B28 GF 30 9 FR natural (8069)PA6 GF 30 FR(40)

AKROMID® B28 GF 30 9 FR natural (8069) is a flame retardant PA6 with 30% glass fibres. The flame retardant system is free of red phosphorus and halogens, leading to optimised electrical properties for e-mobility applications. This grade is UL listed with a V0 classification at 1.6mm. Due to its very good flowability, it is characterised by easy processability as well as good surface properties. The material has excellent long-term thermal stability and outstanding mechanical properties.
