Tetrabromophthalic anhydride [ 632-79-1 ]

White or light yellow, yellow powder, melting point 270-281 ° C, bromine content not less than 67%, sulfate is not higher than 0.3%, the moisture is not higher than 0.2%. Soluble in nitrobenzene, DMF, slightly soluble in acetone, toluene, xylene, methanol, 4-dioxane 2, tetrahydrofuran, acetic acid, etc. The decomposition temperature of 400 ° C.
Mainly used for reactive flame retardant, used for polyester, unsaturated polyester, epoxy resin. As additive flame retardants and antimony trioxide, used in polystyrene, polypropylene, polyethylene and ABG resin, and can be used in other engineering plastic and synthetic materials. Can also be used for the synthesis of other fine chemicals. This product has the bromine content is high, the added quantity is little, flame retardant characteristics, with good effect and high saturation. Both high crosslinking density, light, heat stability, good drink excellent weatherability, but also has good antistatic effect, is added in the resin does not affect the mechanical properties and electrical insulating properties. Low toxicity, no environmental pollution. Is the ideal reactive flame retardant agent and adding flame retardant agent.
