PA6.6/6 – Polyamide 6.6/6 PA66 + PA 6 FR (30)

AKROMID® C3 1 FR natural (8050)

AKROMID® C3 1 FR natural (8050) is an unreinforced, flame retardant and heat stabilised PA6/6.6 blend. Listed to UL 94 in all-colours, the material is based on a flame retardant system free of red phosphorus and halogens. Due to its very good flowability, an improved surface quality is achieved and it is quite suitable for film hinges. This grade meets the requirements for public transportation (EN 45545-2 and ISO 4589-2) and it is also suitable for applications in the automotive and E&E markets.
