Shape: light yellow powder (particles), tasteless, non-toxic, specific gravity 1.5.Soluble in chloroform, benzene, acetone, carbon disulfide, slightly soluble in gasoline and carbon tetrachloride, insoluble in water, dilute alkali.
Usage: this product is used as an auxiliary accelerator for natural rubber, synthetic rubber and latex.Since free sulfur can be decomposed when heated, it can also be used as vulcanizing agent. The effective sulfur content is 28% of its mass.When used as vulcanizing agent, it is relatively safe at operating temperature. Vulcanizing adhesive has good heat resistance and aging resistance.This product can be used as the main promoter in chlorosulfonated polyethylene rubber, styrene-butadiene rubber and butyl rubber.When used with thiazole accelerator is especially suitable for nitrile rubber, vulcanized rubber compression deformation and heat resistance are excellent.The latex sponge should be used with accelerator Mz.This product is easy to disperse in dry rubber, also easy to disperse in water.No pollution.Commonly used in the manufacture of heat - resistant products, cables, and so on.
Packing :25kg woven plastic bag, paper - plastic composite bag, kraft paper bag.
Storage: it should be stored in a cool, dry and well-ventilated place.Packaged products should avoid direct sunlight.From the date of production, the storage period is 2 years.
Description: this product can be made according to customer requirements for ultrafine powder.
