Import Di-Tert-Butyl Peroxide Diisopropylbenzene — Buy in Bulk from Supplier in China

Di-Tert-Butyl Peroxide Diisopropylbenzene, also known as BIPB, is a crystalline organic peroxide used primarily as a crosslinking agent in elastomers and thermoplastics. This product has a molecular formula of C6H4[C(CH3)2OOC(CH3)3]2, a molecular weight of 338 g/mol, and a CAS number of 2212-81-9. Its theoretical active oxygen content is 9.45%, with a decomposition half-life of 1 minute at 182°C and 10 hours at 118 - 120°C. It is supplied as a white or crystalline powder with a minimum purity of 40% to 96%, depending on the grade.

The product is insoluble in water but partially soluble in ethanol, ether, benzene, and carbon tetrachloride. Commercial grades include BIPB-96 (96% purity, crystalline powder), BIPB-90 (90% purity, white powder), and BIPB-40 (40% purity, white powder with calcium carbonate and silica as carriers). These carrier grades reduce handling risks and improve dispersion in polymer matrices. Typical industry standards require low moisture content and minimal volatile impurities to ensure consistent curing performance in rubber compounding.

This crosslinking agent is widely used in chlorinated polyethylene, ethylene propylene terpolymer, ethylene vinyl acetate, silicone rubber, and nitrile butadiene rubber applications. Buyers include manufacturers of wire and cable insulation, automotive seals, and industrial rubber goods. Packaging is in 5 kg PE bags inside 20 kg cartons. Storage must avoid heat, strong acids, and reducing agents. Transportation requires vibration control and ambient temperature conditions.
