introduction | accelerator DPTT is light yellow powder (granule), tasteless, non-toxic and 1.5 specific gravity. |
use | this product is an autumn ram vulcanization accelerator, which can be used in natural rubber, diene synthetic rubber, butyl rubber, EPDM rubber, chlorosulfonated polyethylene and latex. Heating can decompose dissociated sulfur, and can also be used as a vulcanizing agent. The effective sulfur content is 25% of its weight. This product is safe at operating temperature when used as a vulcanizing agent, and the vulcanized rubber has excellent heat resistance and aging resistance. This product is easily dispersed in dry rubber and water. No pollution. Generally used in the manufacture of heat-resistant products, cables, etc. used as natural, styrene-butadiene, nitrile, butyl, chloroprene, isoprene, chlorosulfonated polyethylene and other rubber accelerator this product is used as an auxiliary accelerator for natural rubber, synthetic rubber and latex. Since it can decompose free sulfur when heated, it can also be used as a vulcanizing agent, and the effective sulfur content is the 28% of its quality. When used as a vulcanizing agent, it is relatively safe at operating temperature, and the vulcanized rubber has excellent heat resistance and aging resistance. This product can be used as the main accelerator in chlorosulfonated polyethylene rubber, styrene butadiene rubber and butyl rubber. When combined with thiazole accelerators, it is especially suitable for nitrile rubber. Vulcanized rubber has excellent compression deformation and heat resistance. When making latex sponge, it should be used together with accelerator WILLING MZ. This product is easily dispersed in dry rubber and water. No pollution. Generally used in the manufacture of heat-resistant products, cables, etc. |
Production method | Sodium pentamethylene dithiocarbamate is prepared by the reaction of hexahydropyridine, sodium carbonate and carbon disulfide, and then treated with sulfur chloride to obtain tetrasulfide double pentamethylene thiuram. |
