Yellowish powder. TBBAER are solids and they have no odor nor warning properties.

Imparts flame retardancy to molding, laminating and casting systems.

These resins are the condensation product of 2,2-bis(3,5- dibromo-4-hydroxyphenyl) propane and epichlorohydrin. Bromine has been incorporated into BADGE-type resins to increase the ignition resistance of such resins by the use of tetrabrominated bisphenol A for the synthesis of the glycidyl ethers. Because bromine substitution reduces the thermal stability of the resins, the products are usually used with or condensed with bisphenol A. They therefore contain less than the theoretical amount of bromine indicated by the chemical formula (18–48% Br). Brominated epoxy resins are used as reactive flame retardants and are applied in electrical and electronics parts and equipment.
