Insoluble sulphur is the transparent, amorphous chain structure of elastic sulphur obtained by heating sulphur powder to boiling (444.6 degrees Celsius), pouring it into cold water and cooling it sharply. It can also be superheated sulfur vapour diluted with inert gas, sprayed in a cold water spray cooled to below 90 degrees Celsius, or sulfur block dissolved in ammonia and immediately spray-dried to obtain. It is called insoluble sulphur because most of it (65%~95%) is insoluble in carbon disulphide. Due to it has the characteristic of insoluble in rubber, so it is not easy to produce early vulcanisation and sulphur spraying phenomenon in the rubber material, and it does not harm the adhesion of the rubber material, thus it can eliminate the slurry coating process, save petrol and clean the environment. At vulcanising temperature, insoluble sulphur is transformed into usual sulphur yellow to exert its vulcanising effect on rubber. It is generally used for particularly important products such as steel wire tyres.
The most important application of Insoluble sulfur (cas 9035 99) is as accelerator and cross-linking agent in the rubber industry; in the tyre industry, a large amount of accelerator and cross-linking agent is needed, which is an indispensable and important auxiliary agent.IS integrates the practicality and the appearance requirements, and it is widely used in some products in which the rubber skin is bonded to the structure, such as white tyre sidestuffs, tire turnovers, and cushioning rubber compound, The application market of IS products is very wide, cable casing, waterproof hose, oil sealing material, raw tape, automobile inner tube Chemicalbook, insulation and protection products, automobile interior parts and other rubber products are all present in IS. IS figure. In addition to industrial applications, the distribution in daily necessities is also very wide. Common light-coloured rubber products on the market often need a large amount of sulphur, such as waterproof rubber shoes, water and electricity construction seals and other special rubber products, as well as household rubber products, toys, latex gloves and other high-grade rubber products.IS can enhance the adhesion between the layers of the rubber, greatly improve the quality of common rubber products, prolong the use of the life of the products, as compared with the ordinary sulphur yellow has a lot of unique advantages.
As a sulphur powder supplier, Insoluble sulfur (9035 99 8) has been steadily supplied, and we hope to promote the development of more fields.
