Tert-butyl perbenzoate (TBPB for short) is widely used in various polymer industries, among which the EPS initiation industry is expected to account for more than 60%, unsaturated polyester curing accounts for about 25%, and the rest are used in polymerization initiators such as ethylene, propylene, and vinyl acetate; the total China domestic TBPB usage is 600-700 tons/month, and the EPS industry is around 350-400 tons/month.
The first-tier benchmark of domestic TBPB production enterprises is CHINASUN SPECIALTY PRODUCTS, with an actual monthly production capacity of about 600 tons/month, half of which is exported and the other half is almost used in the China EPS industry; the second-tier manufacturers following closely are Jiujiang Qianfa Fine Chemical Co., Ltd. (located in Jinshawan Industrial Park, Hukou County, Jiujiang, Jiangxi) and Jiangxi Yuhang New Materials Co., Ltd. (located in Pharmaceutical Industrial Park, Yuanzhou District, Yichun, Jiangxi), with production capacity of about half of CHINASUN SPECIALTY PRODUCTS. Basically, the above three companies occupy more than 80% of the domestic market.
Although LANZHOU AUXILIARY AGENT PLANT CO.,LTD. has a safety production license, it focuses on a variety of high-profit low-temperature products on the one hand, and is also subject to safety and environmental pressures on the other hand, so its TBPB output is not large;
In addition, due to severe domestic internal competition, internationally renowned organic peroxide manufacturers such as Nouryon, Arkema, and United Inititators have gradually abandoned the mainland market, and the extremely small market share is basically outsourced to domestic regular factories.
