The insoluble sulfur vulcanizing agent to be the promotion

The vulcanizing agent is essential for the rubber industry, at present, the largest amount of vulcanizing agent is sulfur, and the sulfur vulcanizing agent is used in the rubber industry with sulfur powder, insoluble sulfur, colloidal sulfur, precipitated sulfur. Among them, the insoluble sulfur has chemically inert and physical inertia, less prone to migration when used in rubber vulcanization, and makes vulcanized rubber tackifier, not blooming, and can reduce the scorch and extend the storage time of rubber is recognized as the best of sulfur vulcanizing agent.

 

Investment Advisor in the chemical industry researcher Chang Yizhi thinks  that the insoluble sulfur vulcanizing agent has the good development potentialin our market . At present, the insoluble sulfur has been widely used in the tire carcass rubber, white sidewall rubber and buffer rubber for the manufacture of tires, hoses, conveyor belts, automotive rubber parts, rubber rollers, oil seals, cables, rubber, latex products and light products and other products.

 

Released by the Investment Advisor in the 2010-2015 rubber chemicals industry investment analysis and forecast report, the amount of the insoluble sulfur used in the vulcanizing agent is 2% -4% of the natural rubber. According to the amount of raw rubber material, the amount of the annual domestic insoluble sulfur vulcanizing agent is up to 10 million tons.

 

However, Chang Yi zhi also pointed out that because of small-scale production,  relatively backward equipment and relatively high cost, at present the vulcanizing agent used in most of the domestic rubber enterprises are still mainly sulfur, a small number of ordinary sulfur and insoluble sulfur mix,only the production of radial tires and other varieties all with insoluble sulfur.

Released by the Investment Advisor in the 2010-2015 rubber chemicals industry investment analysis and forecast report, the amount of the insoluble sulfur vulcanizing agent is less than 10% of the amount of vulcanizing agent, while the amount of the use of the insoluble sulfur vulcanizing agent  accounts for 50% -60% of the total amount of vulcanizing agent.

 

So, the applications of the insoluble sulfur vulcanizing agent in our country has the gap compared with the developed countries. Therefore, Chang Yi zhi thinks that applications of the insoluble sulfur vulcanizing agent have yet to be promotion.
