Nylon flame retardants

GF Reinforced PA66 (Bloom-Free) Retardant CR-M1431

Inovia CR-M1431 is a novel halogen-free flame retardant, developed for 30% glass fiber reinforced PA66. It can get UL94-V0 at 0.8mm and 1.6mm, with blooming-free over 3000hrs (85℃, 85%RH). Compared to conventional flame retardant, the FR performance of the modified mold is more stable, with better mechanical properties.
