Product Features
  • Description

    DPTT-70 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 has heat resistance and excellent aging resistance.

    This product can be the main accelerator in chlorosulfonated polyethylene rubber, styrene butadiene rubber, and butyl rubber. When used in combination with thiazole accelerators, it is particularly suitable for nitrile rubber and is 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 accelerator when used in combination with sulfenamide accelerators. A small amount of JXBHgran DPTT-70 is used in combination with thiuram accelerators to achieve a very good anti-aging performance.

  • Dosage

    0.2-3.5 phr.

  • Application

    It generally used for a variety of heat-resistant rubber products, cables and so on.

  • Packing

    25 kg in carton box with polyethylene bag liner.
