Tetrabromophthalic anhydride CAS 632-79-1

Structural formula： 

Product Description：

Properties and Usage:

Tetrabromophthalic anhydride  is a bromine-containing organic compound, used as a reactive and additive flame retardant

Main application areas:

1. Flame retardant

Tetrabromophthalic anhydride is widely used in materials such as plastics, resins, textiles and coatings due to its efficient flame retardant properties. During the combustion process, it can effectively release bromine free radicals, thereby inhibiting the spread of flames and significantly reducing the generation of smoke and toxic gases. Especially in polyester, epoxy resin and unsaturated polyester resin, tetrabromophthalic anhydride has become an important additive to improve flame retardant properties.

2. Crosslinking agent for epoxy resin and polyester resin

As a crosslinking agent for epoxy resin and unsaturated polyester resin, tetrabromophthalic anhydride can not only enhance the flame retardant properties of the material, but also significantly improve its mechanical strength, heat resistance and chemical stability

3. Key additives in the plastics industry

In the plastics industry, tetrabromophthalic anhydride, as an important additive, can significantly enhance the heat resistance, chemical resistance and stability of engineering plastics. It is particularly suitable for the manufacture of high-performance plastics that are resistant to high temperatures and chemical corrosion, and is widely used in the fields of automobiles, electronics and industrial equipment.

4. High-efficiency flame retardant for polyurethane foam

Tetrabromophthalic anhydride also plays an important role in the production of polyurethane foam. Its high-efficiency flame retardant properties make polyurethane foam materials more suitable for application scenarios with strict requirements on flame retardant properties in the construction, furniture and automotive industries.
