Shape: yellow powder (granules).Density of 1.37 to 1.40.No smell, no smell.Soluble in benzene, acetone, dichloroethane, carbon disulfide, toluene, slightly soluble in ethanol and ether, insoluble in gasoline and water.Stable storage.

Usage: this product is non-discoloration and non-pollution super accelerator, mainly used for natural rubber and synthetic rubber.The activity was about 10% lower than that of promoter TMTD, and the elongation strength of vulcanized adhesive was also slightly lower.The critical temperature of vulcanization is 1210C, and the aftereffect is larger than that of thiocarbamates and thiocarbamates.When using this product, the sulfur dosage range is large.This product can be used alone, also can be used with thiazoles, aldehydes, guanidines and other promoters, is the thiazoles promoter active agent.Delayed vulcanization was found in general purpose (gn-a) butyl rubber.When used with dithiocarbamate in latex, the tendency to vulcanize early can be reduced.This product cannot decompose active sulfur and cannot be used for sulfur free coordination.

Packing :20/25kg woven plastic bag, paper plastic composite bag, kraft paper bag.

Storage: it should be stored in a cool, dry and well-ventilated place.The packaged products should avoid direct sunlight, and there should be no overlapping stacking between the trays. Overlapping stacking or temperature exceeding 35℃ will lead to abnormal compression of the products.From the date of production, the storage period is 2 years.
