Rubber Accelerator DPG (D)
Chemical Name: Diphenyl guanidine
Molecular Formula: C*3H*3N3
Molecular Weight:**1.*7
CAS NO:*******7
 
Properties:Grayish-white powder(granule)No taste, no poison. Densiy is 1.****1.*9. 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.

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

Packaging:*5kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag.
