4,4′-thiobis(6-tert-butyl-m-cresol) is a highly effective antioxidant widely used in various industries. In the rubber industry, it can prevent the rubber from aging and degradation caused by heat, oxygen, ozone, and mechanical stress. By inhibiting the free - radical chain reaction, it extends the service life of rubber products, improving their physical and mechanical properties. In the plastics industry, it is added to various plastics, such as polyethylene, polypropylene, and polystyrene, to enhance their heat resistance and oxidation resistance. It can also be used in the lubricant industry to prevent the oxidation and deterioration of lubricating oils, thereby maintaining their viscosity and lubricating performance.
When using Factory Supply 4,4′-thiobis(6-tert-butyl-m-cresol), the following points should be noted. In rubber processing, it can be added directly to the rubber compound during the mixing process. The recommended dosage is usually 0.5 - 3 parts per hundred rubber (phr), depending on the specific rubber type, processing conditions, and performance requirements. In plastics, it can be incorporated during the extrusion or injection - molding process. For general plastics, a dosage of 0.1 - 1% by weight is often sufficient. In the lubricant industry, it is usually added during the blending process of lubricating oils, with an appropriate dosage determined by the type and quality requirements of the lubricating oil.
A rubber product manufacturing company was facing the problem of rapid rubber aging in their conveyor belts. The conveyor belts were exposed to high temperatures and mechanical stress during operation, resulting in cracks and reduced strength over a short period. After consulting with the supplier of Factory Supply 4,4′-thiobis(6-tert-butyl-m-cresol), they decided to add this antioxidant to their rubber compound. They added 2 phr of the antioxidant during the mixing process. After production, the new conveyor belts showed significantly improved heat resistance and aging resistance. The service life of the conveyor belts was extended from 6 months to over 18 months, reducing the company's replacement costs and improving production efficiency. Another example is a plastics manufacturer producing plastic pipes. They added 0.5% of this antioxidant to their polypropylene resin during extrusion. The resulting plastic pipes had better UV resistance and oxidation resistance, which was very important for outdoor applications. The pipes maintained their mechanical properties and appearance for a longer time, increasing customer satisfaction.
