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: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
Packing:In woven bag lined with plastic, 25KG/bag.
Storage:Keep container tightly closed in a cool, well-ventilated place. The shelf life is 2 years.
