2,2-比斯(溴甲基)propane-1,3-diol is a reactive flame retardant used in polymer
materials such as rigid ammonia foams, resins, and coatings.It is characterized by high
flame retardancy, light stability and transparency.
Its high bromine content and easy combination with polyurethane make it
particularly suitable for use in rigidpolyurethane foams. It is also increasingly
used in free-CFC foam systems to increase its flame retardant capability rating.
