Features: Willing insoluble sulfur with the high dispersion and high stability, mainly reflected in the following, It can avoid the blooming of rubber in the storage period and maintain the sizing components with uniform performance; it can improve the adhesion of rubber and rubber, rubber and steel or synthetic cord to overcome the poor adhesion caused by the blooming of rubber and avoid to contaminate the rubber products and molds; It also can increase the adhesion of rubber and other materials, thus reducing scorch in the process of mixing and storage. Meanwhile, it will be not migration in the adjacent layer to keep the molding at the surface of rubber. Willing insoluble sulfur can shorten the curing time, reduce the dosage of sulfur and improve the aging properties of rubber products.  
Applications: It is a non-blooming vulcanizing agent used for unsaturated elastomers, widely used in NR, NBR,SBR,and EPDM, and can be used in the manufacture of tires, tubes, rubber belt,foot wear, rubber roller, wire and cable, seals, latex products and various light-colored rubber products.
Packing: 25kg / bag
Effective period: 1 year

 Main business

      The company is mainly engaged in the research and development, production and sales of rubber auxiliaries, which are mainly used in the rubber industry.

      Through years of development, the company can now use the cleaning process to produce thiazoles, sulfenamides, thiurams, dithiocarbamates, vulcanizing agents and other rubber additives, with an annual production capacity of nearly 20,000 tons. The company has become the most complete enterprise of domestic accelerators. The comprehensive quality indicators of major products have reached or exceeded the level of internationally renowned enterprises. The output of thiram and dithiocarbamate products ranks in the same industry in the country. In the first place, it has become one of the world's most influential manufacturers of accelerator products, and has maintained a leading position in the development and application of new additives and innovative additives.
