PA6.6/6 – Polyamide 6.6/6 PA66 + PA6 GF25 FR(40)

AKROMID® C3 GF 25 1 FR black (7246)

AKROMID® C3 GF 25 1 FR black (7246) is a 25 % glass fiber reinforced, flame retardant and heat stabilised PA6/6.6 blend, colored in black. Listed to UL 94 in black V0 @ 0,4 mm and all-colours V0 @ 0,8mm, 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 is also suitable for applications with high strength requirements in the automotive and E&E markets.
