PA6 – Polyamide 6 PA6 FR
AKROMID® B3 1 FR natural (6437)AKROMID® B3 1 FR natural (6437) is an unreinforced, flame retardant and heat stabilised PA6. Listed to UL 94 in all-colours, the material is based on a flame retardant system that is free of red phosphorus and halogens. Due to its good flowability, an improved surface quality is achieved. This grade meets the requirements for public transportation (EN 45545-2) and is also suitable for housing, fasteners and cable connectors in the E&E markets.
