Properties:  Yellow powder. No taste, no poison. The specific density is 1.5. Soluble in Chloroform, Benzene, Acetone, CS2, and partly soluble in gasoline and CCl4, insoluble in water and alkali of lower concentration.

Usage:

DPTT is an effective primary or secondary accelerator or sulfur donor for use in IIR, CSM, EPDM, NR, IR, SBR and CR.DPTT improves heat resistance and aging properties of vulcanizates. It is particularly suitable for light-colored stocks For rich sulfur content of 25%, it could be used as cure agent. In system of SBR and NBR, it would be used as the primary cure agent. No poison and no pollution. Easily dispersed in rubber system.
