PA6.6/6 – Polyamide 6.6/6 PA6.6/6 GF30 FR(40)
AKROMID® C3 GF 30 1 FR grey (8384)AKROMID® C3 GF 30 1 FR grey (8384) is a 30 % glass fiber reinforced, flame retardant and heat stabilised PA6/6.6 blend colored in laser-markable grey similar to RAL 7035. 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 is also suitable for E&E applications (e.g. control cabinets) as well as for railroad applications and meets the requirements for public transportation (EN 45545-2 R22/23/24 HL3).
