It combines a high bromine content with exceptional stability and is particularly suitable where thermal. hydrolytic and light stability are required. Major uses of it are as a reactive intermediate for high molecular weight flame retardants, particularly in combination with phosphorus. and as a reactive flame retardant for polyurethanes where its high solubi1ity in the system makes it especially useful. It 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 it which is monofunctional and FR-522(DBNPG) which is difunctional. Proper storage of Tribromoneopentyl Alcohol (TBNPA) is essential to maintain its stability and safety. Here are some guidelines for storing TBNPA:Temperature: Keep TBNPA stored in a cool, dry place away from direct sunlight and sources of heat. The ideal storage temperature is typically below 25°C (77°F). Avoid extreme temperatures as they can affect the stability and performance of the compound.Ventilation: Store TBNPA in a well-ventilated area to prevent the accumulation of vapors. Adequate ventilation helps dissipate any fumes that may be released from the compound, reducing the risk of exposure.
