Ethylene thiourea is an imidazoline vulcanization accelerator. The pure product is white needle-like crystals, slightly soluble in water, and has a weak ammonia odor. Ethylene thiourea was once widely used in the curing of chloroprene rubber and other rubbers, and was also used in a small amount to produce insecticides, but due to its harm to the human body, it has been basically eliminated.

Chemical Properties:

White to light green crystals with a weak ammonia odor. Slightly soluble in cold water, easily soluble in hot water, slightly soluble in ethanol, methanol, acetic acid and gasoline at room temperature, insoluble in acetone, ether and chloroform.

  1. Ethylene thiourea used as an accelerator for neoprene, chlorosulfonated polyethylene rubber, chlorohydrin rubber, and polyacrylate rubber.
  2. Ethylene thiourea is an imidazoline vulcanization accelerator, which can be used for chloroprene rubber, chlorohydrin rubber, chlorinated polyethylene, etc., and is especially suitable for use as an accelerator for chlorobutylamine in non-vulcanized systems. It can be used at 100-500℃, select the appropriate matching system, and then the best vulcanization can be carried out quickly, and the operation is completely safe. The vulcanized products have high tensile strength and small permanent compression set. The non-vulcanized system used in W type (that is, 54-1 chloroprene rubber) has a significant effect. It is usually used in conjunction with zinc oxide and magnesium oxide, and is mainly used for neoprene products such as industrial products, covered wires, shoes and clothing. Ethylene thiourea is an auxiliary brightener for copper sulfate. This product is also used as a fine chemical intermediate for the manufacture of antioxidants, insecticides, fungicides, dyes, drugs and synthetic resins. In 2000, there were three companies mainly producing ethylene thiourea in China, France, and Japan, two in Germany, and one in Brazil, the Netherlands, India, Italy, and Switzerland. However, due to its hazard to the environment and hard to decompose in the soil, the use of ethylene thiourea is decreasing. The ethylene thiourea currently used is mainly polymer particles, in order to avoid workers’ skin contact or inhalation of ethylene thiourea dust.
  3. Ethylene thiourea is soluble in hot alcohol solution. Used as brightener for copper plating, often used in conjunction with acid copper plating brightener M, SPS, etc.
  4. 2-imidazolidinethione is a pesticide used in the production of fruits and vegetables. It is also used as a new type of contrast agent for MRI studies based on proton chemical exchange-dependent saturation transfer (1). 2-imidazolidinethione is also a corrosion inhibitor (2) due to the adsorption of molar species. Drinking Water Contaminant Candidate List 3 (CCL3) compounds are based on the US Environmental Protection Agency (EPA), environmental and food contaminants.
