Insoluble sulfur, it is mainly used as a high-grade accelerator and vulcanizing agent in the rubber industry, and is widely used in the production of tires and other rubber composite products, such as tire carcass rubber, cushioning rubber, white sidewall rubber and turning It can also be used in rubber products such as tires, hoses, tapes, etc. to bond rubber and framework materials. It can also be used in rubber products such as cables, rubber rollers, oil seals, and rubber shoes. It can also be used in light-colored rubber products with a large amount of sulfur. Because insoluble sulfur can make the meridian wire, steel wire and rubber stick more firmly, effectively prevent the rubber from frosting, and improve the heat resistance and wear resistance of the tire. Therefore, insoluble sulfur is an indispensable and important raw material in tire production.
Using sulfur as a vulcanizing agent is still widely used in the rubber industry. As a variant of sulfur (S)—insoluble sulfur (IS), it is widely used in the manufacture of tires, rubber shoes, rubber hoses, tapes, and sundries at home and abroad. It is widely used in the bonding of rubber and steel wire.
Insoluble sulfur (IS) is a linear long-chain high molecular polymer processed by sulfur (S). The number of sulfur atoms in the molecular chain is as high as 108 or more; it has the viscoelasticity and molecular weight distribution of a polymer; it is insoluble in carbon disulfide , So it is called insoluble sulfur.
