Product details

Insoluble sulfur, which is mainly used as a kind of advanced accelerator and vulcanization agent in the rubber industry, is widely used in the Adhesive Products production and manufacture of tires and other rubber composite products, such as tire body rubber material, buffer rubber material, white tire side rubber and flip tire, rubber hose, tape and other rubber and skeleton materials, and can also be used in the rubber material of cable, rubber roller, oil seal, rubber shoes and other rubber products. At the same time, it is also used in light-colored rubber products with large amount of sulfur. Because the insoluble sulfur can make the meridian, steel wire and rubber paste more firmly, effectively prevent the rubber spray, improve the heat resistance and wear resistance of the tire. Therefore, insoluble sulfur is an essential and important raw material in tire production.

Sulfur as a vulcanizing agent in the rubber industry IS still widely used, as a variant of sulfur (S) - insoluble sulfur (IS), more widely used at home and abroad for tires, SPU Sealant, rubber shoes, rubber hose, tape, miscellaneous products manufacturing, and has been widely used in rubber and steel wire bonding.

Insoluble sulfur (IS) is a kind of linear long chain polymer which is deeply processed by sulfur (S), and the number of sulfur atoms on the molecular chain is more than 108. There are viscoelastic and molecular weight distribution of polymers; Insoluble in carbon disulfide, so called insoluble sulfur. Insoluble sulfur (IS) is mainly used in rubber products and has the following advantages over ordinary sulfur:

1. The glue is not sprayed during the storage period. Keep the composition and properties of the rubber material uniform; To overcome the shortcomings of poor adhesive force caused by spray; Prevent contamination of products and molds and remove the coating process added to overcome frost spraying, providing conditions for production linkage.

2. There is no migration in the adjacent rubber layer. Especially in the compound of butyl and butyl rubber, the migration rate of ordinary sulfur is very high, and it can be avoided after adding insoluble sulfur.

3. Reduce burning during mixing and storage.

4. Shorten curing time. When the vulcanization temperature is reached, it has an "activation stage", that is, chain depolymerization, which speeds up the vulcanization rate, reduces the amount of sulfur, and is conducive to the improvement of the aging performance of the product.

5. It is conducive to the adhesion of rubber and other materials, and can improve the adhesion force when used with S.

6. Indispensable auxiliaries in radial tires. In the production of radial tires, it can effectively avoid spraying frost, and it is not easy to produce early vulcanization, and maintain good viscosity of the rubber, which is conducive to the molding operation, and ensure the uniformity of vulcanization and ensure the stability of product quality.
