Tris(tribromoneopenthyl)phosphate Usage And Synthesis

Description

Tris(tribromoneopenthyl)phosphate is an additive Flame Retardant developed for applications such as PP and HIPS to reach class V-2 according to the UL 94 standard, with outstanding UV and light stability.

Properties and Applications

The combination of both a high bromine content (70%) and phosphorous (3%) contributes to its excellent flame retardant efficiency. The chemical structure of the brominated part is responsible for its excellent UV and light stability leading to a good appearance of the molded part. The high melting temperature (181˚C) permits production of highly filled masterbatch concentrates. In addition, as Tris(tribromoneopenthyl)phosphate is melt blendable and melts at the processing temperature of PP, it is easy to process and can improve flowability. It solves the previously unanswered problem of blooming in flame retardant grades of PP.
