Flame Retardants, Polybutylene Terephthalate (PBT)

FRP-750AH Red Phosphorus Flame Retardant Masterbatch

FRP-750AH is a high-efficiency red phosphorus flame retardant masterbatch designed for engineering plastics that require strong, stable, halogen-free flame performance. It uses a new-generation compatibilizer carrier and twin-screw melt compounding to achieve ≥70 percent red phosphorus content with low phosphine release and low precipitation. FRP-750AH supports UL94 V-0 performance at low addition levels and retains mechanical and thermal stability across reinforced and unreinforced polymer systems.

Attributes

Key Features and Benefits

≥70 percent red phosphorus loading provides high flame-retardant efficiency at low dosage.
