Sodium metabisulfite plays an important role in the rubber industry. Rubber is a polymer material, usually prepared by polymerization reaction. Sodium metabisulfite is widely used as an important additive in the rubber industry. Qingdao Tianya Chemical Co., Ltd supplies China sodium metabisulfite with high performance to rubber industry.
Sodium metabisulfite can be used as a vulcanizing agent for rubber. Vulcanization is an important step in the preparation process of rubber products, which can form cross-linked structures between rubber molecular chains, thereby improving the mechanical properties and aging resistance of the products. Sodium metabisulfite can react with rubber molecules during the vulcanization process, promoting cross-linking reactions. Meanwhile, sodium metabisulfite can also inhibit side reactions such as oxidation and cracking, thereby extending the service life of rubber products.
Sodium metabisulfite can be used as a rubber processing aid. During the processing of rubber, various additives need to be added to improve its processing performance and product performance. Sodium metabisulfite can be used as a rubber processing aid to improve the processing flowability, plasticity, and elasticity of rubber. At the same time, sodium metabisulfite can also suppress the static electricity and oxidation reactions generated during rubber processing, improving the stability and quality of the product.
Sodium metabisulfite can also be used as an antioxidant and antioxidant in rubber products. Rubber products are gradually aging due to various environmental factors during use. Sodium metabisulfite can react with active groups on the surface of rubber products to form a protective film, thereby delaying the aging process of rubber products. At the same time, sodium metabisulfite can also react with free radicals in the product, terminating the oxidation reaction, thereby improving the weather resistance and heat resistance of the product.
Sodium metabisulfite also has anti-static properties. In certain specific application scenarios, rubber products need to have anti-static properties to prevent safety issues caused by the accumulation and discharge of static electricity. Sodium metabisulfite can reduce the charge density on the surface of rubber products by adsorbing and neutralizing charges, thereby achieving anti-static effects. This anti-static function can make rubber products widely used in fields such as electronics and chemical engineering.
