This product is a yellow powder (granular); 1.37-1.40 density; no smell and no ambiguity; soluble in benzene, acetone, two ethyl chloride, carbon disulfide, toluene, slightly soluble in ethanol and ethyl ether, insoluble in water and gasoline; storage stability.


This product is no color, no pollution ultra accelerator, mainly used for natural and synthetic rubber. The activity was about 10% lower TMTD accelerator WILLING, vulcanized rubber tensile strength is slightly lower. The critical curing temperature of 121 DEG C aftereffect is larger than two thiuram disulfide and two dithiocarbamate accelerator, anti scorching quality. When using this product range is large amount of sulfur. This product can be used alone, can also be used with thiazole, aldehyde amine, guanidine promoter and active agent, is thiazoles. In general type (GN-A type) have delayed vulcanization butyl rubber in effect. And with two dithiocarbamate in the latex, can reduce the tendency of early rubber vulcanization. This product can decompose active sulfur, sulfur free and cannot be used for.
