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

Application: NR and synthetic rubbers used in the speed of the accelerator, but also as thiazoles, thiurams, and the sulfenamide accelerator activators, plasticizers in neoprene, the role of peptizers. DPG storage-stable better performance than the two dithiocarbamates and thiuram accelerators, but not so lively. In the fluorine silicide process latex foam, DPG as a secondary gelling agent (foam stabilizer) is mainly used in the manufacture of tires, rubber soles and other products.
