Application: DPTT is as the secondary accelerator for NR, SBR, EPDM, and NBR. As free sulfur can be decomposed when heating, it can also be used as a curing agent, the effective sulfur content is 28% of its quality. As curing agent, DPTT is safe accelerator under the operating temperature, with high cross-linking density, lower return to the original tendency,excellent heat and aging resistance.

DPTT can be used as main accelerator in CSM, SBR, IIR. When combined with thiazole, it is particularly suitable for NBR.

DPTT can be used in latex sponge combined with ZMBT. No pollution. Generally used in the manufacture of heat-resistant products, cables and so on.

Packaging: 25kg bag, paper with plastic film bag, Kraft paper bag or jumbo bag.

Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 1 year.
