Nature: Light yellow powder with special odor and bitterness, non-toxic. Soluble in benzene, ethanol, acetone, ether, carbon disulfide, chloroform and a solution of alkali and alkali metal carbonate, slightly soluble in hot water, insoluble in dilute acid, gasoline and water. It is flammable and will burn when exposed to fire. The combustion temperature is 515-520 °C. It will be charged by grinding and there is a danger of explosion in the dust state. Storage is stable.

Function: general-purpose accelerator. Widely used in a variety of rubber. It has a rapid promoting effect on natural rubber and general sulfur vulcanized synthetic rubber, and has a wide vulcanization flatness. The critical temperature of vulcanization is low (125 ° C). It has early vulcanization during mixing operation, but it can be used as vulcanization retardant and anti-squeezing agent in neoprene and sulfur-free vulcanization systems. This product requires zinc oxide and fatty acid activation, thiuram, dithiocarbamate, aldehyde amines, anthraquinones and other promoters and lead oxide, magnesium oxide, magnesium carbonate, etc. can increase its activity. It can be used as a promoter of butyl rubber in combination with thiuram disulfide and bismuth dithiocarbamate. Together with the tribasic lead maleate, it can be used in light-colored water-resistant chlorosulfonated polyethylene compounds.

This product can be applied in latex in the form of sodium hydroxide solution. When added to the latex in the acid state, the stability of the latex is lowered. It is used slowly in latex and is generally used in combination with dithiocarbamate. When used together with diethyldithiocarbamate diethylamine, the vulcanization can be carried out at room temperature. This product can give vulcanized rubber good aging resistance and wear resistance. Depending on the amount, the tensile stress can be high or low.

This product can be used as a chemical plasticizer. In the rubber without adding sulfur and filler, the heating operation can increase the plasticity of natural rubber. This is called "M plasticization".
