[Product Performance]
White to off-white needle crystals, or crystalline powder. Insoluble in water, slightly soluble in aliphatic hydrocarbons, soluble in hot ethanol, acetone and carbon tetrachloride, soluble in benzene.
[Scope of application]
It can be used as an effective accelerator for sulfur vulcanization of natural rubber and synthetic rubber (butylbenzene, cis-butyl, butyl, EPDM, vinylene, etc.), and can be used as a vulcanizing agent alone. Active sulfur can be decomposed under the degree of vulcanization, its content is about 27%, no pollution, no discoloration can be used for light color, coloring, transparent products. The vulcanized rubber has the advantages of high mechanical properties, high ozone resistance, good ozone resistance and no scorching of the rubber compound.
