FAQ - Technical & Supply Chain
-
Q:
What is Diphenylguanidine (DPG) CAS 102-06-7?
A: Diphenylguanidine, commonly abbreviated DPG, is a guanidine rubber chemical identified by CAS 102-06-7 and molecular formula C₁₃H₁₃N₃. It is also called N,N'-diphenylguanidine or 1,3-diphenylguanidine. In rubber processing it is known mainly as a vulcanization accelerator and activator. -
Q:
What is DPG used for in rubber processing?
A: DPG is used as a medium-speed accelerator for natural rubber and synthetic rubber. It is commonly added as a secondary accelerator with thiazole, thiuram, or sulfenamide systems to activate the cure and improve cure speed. It is also used in silica-filled compounds to support silane coupling, and in NR/SBR latex as a gelling agent for foam processes. -
Q:
What grades and typical properties should be confirmed?
A: Common commercial material is around 97% or higher and is supplied as a white to light-yellow or grayish-white powder, with granular grades also available. Typical properties include a melting range near 146-152 °C, density around 1.13-1.19 g/cm³, solubility in alcohol, acetone, chloroform, or benzene, and low water solubility. Confirm assay, melting range, moisture, ash, and amine impurities for the intended compound. -
Q:
How should DPG be stored and handled?
A: Store DPG in tightly closed containers in a cool, dry, ventilated area away from heat, strong oxidizers, and incompatible materials. Avoid dust generation and use appropriate PPE during weighing and mixing. The powder is generally stable in open air, but normal chemical-handling and housekeeping controls should still be followed.
