Main features
The product is light yellow needle crystals recrystallized from benzene, relative density 1.50, melting point 180°C, slightly soluble in benzene, dichloromethane, carbon tetrachloride, acetone, ethanol, ether, etc. at room temperature, insoluble in water, acetic acid Ethyl, gasoline and alkali. The toxicity is small and no special protection is required. However, when there is dust, there is a danger of explosion. In case of fire, it can burn.
Applications
This product is a general-purpose Accelerant for natural rubber, synthetic rubber and reclaimed rubber. It is easy to disperse and does not pollute in rubber. Vulcanizates have good resistance to aging, but articles that are in contact with the vulcanizates tend to have a bitter taste and are therefore not suitable for rubber products that come in contact with foods. Can be used to manufacture tires, hoses, tape, tape, general industrial rubber products.
This product is usually used together with thiuram, dithiocarbamate, silica gel, and guanidine accelerants to increase activity. Zinc oxide and stearic acid are required. Usually 1-2 servings. Refined products for the production of pharmaceutical intermediates AE active esters
