PC Retardant MB-M565
MB-M565 is a novel flame retardant developed for PC injection mold (IM) products. MB-M565 does not contain any halogen, nor requires adding anti drip agents(PTFE). Therefore, it is completely PFAS FREE. When used together with toughening agents, it can achieve UL94-V0 for PC at a thickness of 1.6mm without affecting its impact strength. This provides a perfect solution for PFAS FREE PC IM products.
1. Materials:
