Properties: Grayish-white powder(granule)No taste, no poison. Density is 1.08--1.19. Soluble in acetone, ethyl acetate, benzene, alcohol, slightly soluble in CCl4; Insoluble in water and gasoline.

Application: Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process.

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

Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
