FR-513

Chemical Name:
Tribromoneopentyl alcohol
Formula:

C5H9Br3O

CAS Number:
36483-57-5
Bromine content (%):
73.0
Molecular Weight:
324.9

General & Use:

FR-513, tribromoneopentyl alcohol is a reactive flame retardant containing about 73% aliphatic bromine. It combines a high bromine content with exceptional stability, and is particularly suitable where thermal, hydrolytic and light stability are required.

FR-513 is used as a reactive intermediate for high molecular weight flame retardants, particularly in the production of phosphorus and bromine containing FRs.

FR-513 high solubility in polyurethane systems alse renders its use as a reactive flame retardant for polyurethanes. Here FR-513 reacts through its single hydroxyl function to form pendant urethane groups. Its high bromine content and good compatibility in CFC- free PU systems enables high standards of fire retardancy to be reached together with good foam properties in both rigid and flexible PU. Effective combination of properties may be achieved by use of mixtures of FR-513 which is monofunctional and FR-522 (DBNPG) which is difunctional.
