PA6.6/6 – Polyamide 6.6/6 PA66 + PA 6 FR (30)
AKROMID® C3 1 FR black (5266)AKROMID® C3 1 FR black (5266) is a 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 that is free of red phosphorus and halogens. Due to its 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 is also suitable for applications in the automotive and E&E markets.

Processing information
The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
