Nylon flame retardants

Transparent Semi-Aromatic PA Flame Retardant CR-S5317

CR-S5317 is a novel halogen-free flame retardant developed specifically for semi-aromatic transparent nylon. When compounded with the flame retardant DOPO, it can get UL94-V0@0.8-1.6mm while maintaining the material's transparency. Surprisingly, the physical and mechanical properties of the transparent nylon are improved, and its process-ability is significantly enhanced. There is a moderate decline in thermal performance. The transparent flame-retardant nylon has typical application areas including electrical/electronic applications, automotive industry, electrical appliances, and containers.
