Zinc dimethyldithiocarbamate

Product name:Zinc dimethyldithiocarbamate
CAS: 137-30-4
Molecular Formula: C6H12N2S4Zn
Molecular Weight: 305.84
Product description:This product is used as natural rubber, synthetic rubber and latex promoter commonly. Especially suitable for butyl rubber and nitrile rubber, 3-20 can also be applied to three yuan. Vulcanizing temperature about 100 ℃, the activity and accelerator TMTD similar, but at low temperature, strong activity of charred tend to be large, mixing with easy cause early sulfide. The product of thiazole, times sulfonamide promoter have activation, can make the second promoter. And accelerator DM and, with the increase of the dosage of the DM scorch resistance also increase. This product in the latex sulfide slower when used alone, often with other promoters. It is easily dispersed in rubber, suitable for light and beauty products. Mainly used for latex products, can also be used for the vulcanizates pulp, tape, cold vulcanized products. In the United States, PZ has been approved by the food and drug administration (FDA), can be used for food in rubber products.
