Chemical name of rubber accelerator DM: 2,2'-dithiobisbenzothiazole. The product recrystallized from benzene is light yellow needle crystal, relative density 1.50, melting point 180 ℃, slightly soluble in benzene, methylene chloride, carbon tetrachloride, acetone, ethanol, ether, etc., insoluble in water, ethyl acetate, gasoline and alkali at room temperature. It can be used in the manufacture of tires, hoses, adhesive tapes, adhesive tapes, general industrial rubber products and so on.
1, Accelerator DM (120-78-5) is a universal accelerator for synthetic rubber, natural rubber and recycled rubber, its performance and use are basically similar with accelerator M, but the curing temperature is higher, the after-effect is significant, no need for early curing, safe operation.
2, This product is only in the slow vulcanization speed, usually with dithiocarbamate, thiuram, aldehyde amine, clothing accelerator and use.
3、Adding this product in neoprene will have plasticizing effect. It can be used as the binder of neoprene, especially the anti-scorch agent of G-type neoprene. Vulcanized rubber using this product has excellent aging resistance, but because but can be used in the manufacture of tires, rubber belts, rubber hoses, rubber shoes and general industrial products.
