English name: accelertor NS Chinese Synonyms: accelerator TBBS; N- tert-butyl-2-benzothiazole sulfenamide; vulcanization accelerator NS; N- tert-butyl-2-benzothiazole sulfonamide CAS ??? No. : 95-31-8 Formula: C11H14N2S2 MW: 238.37 toxicity: low toxicity Molecular Structure: Properties: 1. pale yellow or brown powder; 2. a melting point above 104 ℃, relative density of 1.26 to 1.32; 3. soluble in benzene , methylene chloride, ethyl acetate, ethanol, soluble in gasoline, insoluble in water, dilute acid, dilute alkali solution. Applications 1. accelerant NS used as butadiene rubber, isoprene rubber, natural rubber, styrene-butadiene rubber, natural rubber, reclaimed rubber aftereffect accelerator. It has excellent resistance to scorch performance advantages and short curing time at operating temperature without burning dangerous, but at the curing temperature promoting strong, especially in natural rubber aftereffect larger. 2. This product needs with zinc oxide and stearic acid, may also fall Lamb, aldehyde amines, dithiocarbamate salts, guanidine type accelerator and acidic substances activation. 3. This product contamination slight, almost no discoloration. It can be used to produce light or bright color crystal rubber, mainly used in the manufacture of tires, hoses, plastic, rubber, cables and general industrial products.
