GF Reinforced PBT Flame Retardant ER-M1443

ER-M1443 is a novel halogen-free flame retardant developed for glass fiber reinforced PBT, which can achieve UL 94-V0 level of 0.8-1.6mm. The usage of this FR required to obtain V0@1.6mm is lower, compared with traditional flame retardants. Additionally, it affords a good processing flowability.
