Flame Retardant additive for PBT
Introduction:
Introduction:Flame Retardant additive for PBT, grade name FR PBT V0 is a nitrogen/ phosphorus halogen-free flame retardant, designed for glass fiber-reinforced polybutylene terephthalate (PBT) to satisfy the higher requirement of glowing filament. This PBT flame retardant reaches UL94 V0(1.5mm）, GWIT 750(3.0mm）, and GWFI 960℃ 3.0mm）； comply with RoHS requirements, has good heat resistance, is not easily to decompose during processing, low corrosion to mold, and has superior electrical performance。
Applications:
FR PBT V0 can be used in PBT Electrical sockets, switches, Junction boxes, etc.
