Product Description

Rubber vulcanizing agent DTDMMolecular formula: c8h16n2o2sMolecular weight: 236.27CAS NO:103-34-4Properties: white acicular crystal. It smells like fish. Soluble in benzene and carbon tetrachloride, slightly soluble in acetone and gasoline, hardly soluble in ethanol and ether, insoluble in waterUse; This product can be used as vulcanizing agent and accelerator for natural rubber and synthetic rubber. No frost, no pollution, no color change, easy dispersion when using this product. The heat resistance and aging resistance of the vulcanizates obtained when used in the effective and half effect vulcanization systems were good. At the vulcanization temperature, it can release active sulfur, with an effective sulfur content of 2chemicalbook 7%. It is safe to operate. When used alone, the vulcanization speed is slow. When used in combination with thiazole, thiuram and dithiocarbamate, it can improve the vulcanization speed. This product is especially suitable for butyl rubber. It is mainly used for manufacturing tires, butyl inner tubes, adhesive tapes and heat-resistant rubber products. It is also used as an asphalt stabilizer for expressway. It is suitable for natural rubber and synthetic rubber, and has the characteristics of heat resistance, fatigue resistance, reduction resistance, no frost spraying and anti - scorchChinese name of DTDM: 4,4 ′ - dithiodimorphine. It can be used as vulcanizing agent and accelerator of natural rubber and synthetic rubber. When used as a vulcanizing agent, the active sulfur can be decomposed only at the vulcanizing temperature, so the use of this product is safe and will not scorch. The vulcanization speed of this product is slow when used alone, but it can be improved when combined with thiazole, thiuram or dithiocarbamate. Although salicylic acid acidic substances can promote the decomposition of this product and accelerate the curing speed, they can degrade the physical properties of vulcanizates. When used as a promoter, due to the high effective sulfur content of this product, the amount of sulfur can be appropriately reduced. When using this product, the rubber does not spray frost, pollute or change color. The heat resistance and aging resistance of the vulcanizates were good when used in the effective and semi - effective curing systems Technical indicators:
