DBPH has a wide range of applications and my country has become one of the world’s largest production and sales countries.

Bis-dipenta vulcanizing agent, DBPH for short, chemical name is 2,5-dimethyl-2,5-dihexane. It is a dialkyl organic peroxide with the chemical formula C16H34O4. It appears as a light yellow oily liquid. It has a special odor, is soluble in alcohol, ether, ketone, ester, aromatic hydrocarbons and other organic solvents, and is insoluble in water.

Bis-2-penta vulcanizing agent mainly uses 2,5-dimethyl 2,5-hexanediol, hydrogen peroxide, tert-butyl alcohol, sulfuric acid, etc. as raw materials, and is prepared through dry vulcanization reaction. Bis-25 vulcanizing agent has the characteristics of low volatility, high decomposition temperature, good scorch performance, good thermal stability, and high elongation of the resulting product. It can not only be used as silicone rubber, polyethylene, polyurethane, chlorosulfonated polyethylene, ethylene / Vinyl acetate copolymer and other adhesive cross-linking agents, can also be used as a high-temperature vulcanizing agent for vinyl silicone rubber and a degradation agent for polypropylene, etc., and have a wide range of applications.

At present, our country is one of the largest rubber producers in the world, and the total amount of domestically produced rubber has shown a steady growth trend. According to data from the National Bureau of Statistics, domestic synthetic rubber production in 2021 will be 8.117 million tons, a year-on-year increase of 2.6%. As an important type of rubber additive, the market demand for bis-25 vulcanizing agent has continued to increase against the background of steady increase in domestic rubber production, which has led to continuous improvement in production capacity. According to the “2023-2027 China Double 25 Vulcanizing Agent Industry Market Monitoring and Future Development Prospects Research Report” released by the Industrial Research Center It shows that the domestic production capacity of bis-25 vulcanizing agent in 2021 has exceeded 11,000 tons.

In addition, bis-pentazoline vulcanizing agent is also an excellent polypropylene degradation agent, which can achieve effective degradation of polypropylene. Degradants have good dispersion in polypropylene and are key additives for the production of high-quality polypropylene. In the future, as the domestic polypropylene industry continues to develop towards high-end development, the market demand for degradation agents is expected to continue to increase, which will in turn drive both The dipentanol vulcanizing agent industry continues to develop.

Globally, the leading companies of bis-25 vulcanizing agent include Nouryon of the Netherlands and Arkema of France. In 2021, the global production of bis-25 vulcanizing agent has exceeded 17,000 tons; in the domestic market, Local bis-25 vulcanizing agent companies mainly include Qiangsheng Functional Chemicals, Zinchui Chemicals, Delong Chemicals, Weijingxiwang Fine Chemicals, Huasheng Chemicals, Tongying New Materials, Dunmei New Materials, etc. There are many domestic companies, mainly distributed in the eastern and central regions.

Industrial analysis personnel said that bis-25 vulcanizing agent is a widely used vulcanizing agent and initiator , degradation agent products. In recent years, driven by the rapid development of its application fields, its market demand has continued to increase; at the same time, there are currently a large number of local companies in the double 25 vulcanizing agent market, and domestic production capacity accounts for a high proportion of the global total production capacity. Overall, my country has become the world’s major producer and consumer of bis-25 vulcanizing agent, and the industry shows good development prospects.
