2,2'-Methylenebisbenzothiazole is widely used as a vulcanization accelerator in the production of synthetic and natural rubber. It speeds up the vulcanization process, improving physical properties such as elasticity, strength, durability, wear resistance, and flexibility of rubber products. It is particularly effective in manufacturing tires, belts, hoses, and other high-performance rubber goods. Additionally, it functions as an antioxidant, protecting rubber from degradation caused by external factors like heat, UV light, and oxygen. In the plastics industry, it is used as an additive to enhance the strength and durability of plastic products. It is also applied in the paint, adhesive, and sealant industries to improve bonding properties, adhesion, and overall stability, ensuring that rubber, plastics, and related materials maintain structural integrity under various environmental conditions.
