Description

Rubber Accelerator DPTT Masterbatch is used as an auxiliary accelerator for natural rubber, synthetic rubber and latex. For the decomposition of free sulfur when heated, it can also be used as a vulcanizing agent. The effective sulfur content is 28% of its mass. The operating temperature is relatively safe. Vulcanized rubber heat resistance, excellent aging resistance can be obtained.

This product can be the main accelerator in chlorosulfonated polyethylene rubber, styrene butadiene rubber, and butyl rubber. When used in combining with thiazole accelerators, it is particularly suitable for nitrile rubber and also easily dispersed in water. It does not pollute ,and can be used in the manufacture of heat-resistant products, cables, and so on.

Function

JXBHgran DPTT-70's curing time is short and it has good anti-scorch performance.JXBHgran DPTT-70 can be used as an activator and an auxiliary accelerators when used in combination with a sulfenamide accelerators. A small amount of JXBHgran DPTT-70 is used in combination with a thiuram accelerators to achieve a very good anti-aging performance.
