FR-370

Chemical Name:
Tris(tribromoneopentyl)phosphate
Formula:

C15Br9H24O4P

CAS Number:
19186-97-1
Molecular Weight:
1018.5

General & Use:

FR-370 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. It was designed initially to provide an answer in the fast growing and developing field of PP, where the market was in need of a new more sophisticated flame retardant. 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 of FR-370 (181˚C) permits production of highly filled masterbatch concentrates. In addition as FR-370 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.
