C28 GF 25 FRT grey (8331)PA-Blend

AKROMID® C28 GF 25 FRT grey (8331) is a 25 % glass fiber reinforced, flame retardant and easy flowing PA blend, colored in grey similar to NCS S 3000 N. The material is based on a flame retardant system that is free of red phosphorus and halogens. This grade is suitable for railroad applications and certified to EN 45545-2 R6 and EN 45545-2 R1. To achieve an excellent surface quality a mould temperature of at least 120°C is necessary.
