DPTT (TRA)
Used as an accelerator for synthetic rubber, natural rubber and latex. Because it can decompose free sulfur when heated, it can also be used as a vulcanizing agent, and the effective sulfur content is 25% of its mass. When used as a vulcanizing agent, it is relatively safe at operating temperature, and the vulcanizate has good heat resistance and aging resistance.

| Use | 1. Used as an accelerator for synthetic rubber, natural rubber and latex. Because it can decompose free sulfur when heated, it can also be used as a vulcanizing agent, and the effective sulfur content is 25% of its mass. When used as a vulcanizing agent, it is relatively safe at operating temperature, and the vulcanizate has good heat resistance and aging resistance. 2. This product can be used as the main accelerator in styrene butadiene rubber, chlorosulfonated polyethylene rubber and butyl rubber. When used in combination with thiazole accelerators, it is particularly suitable for nitrile rubber, and the vulcanizate has good compression deformation and heat resistance. In the manufacture of latex sponge, it is appropriate to use the accelerator MZ in combination. 3. The product is easy to disperse in dry rubber and water without pollution. Generally used in the manufacture of heat-resistant products, cables, etc. |
