CAS NO: 102-06-7
Specification: NO. Item Unit Specification
1 Appearance - Grayish-white powder
2 Initial M.P. (Min) °C 144.0
3 Loss on drying (Max) % 0.30
4 Ash (Max) % 0.40
5 Residue on 150µm sieve (Max) % 0.10

Properties: No odor or poison. Specific gravity:1.13--1.23. Soluble in chloroform, toluene benzene and ethanol; Insoluble in gasoline and water. Not hygroscopic.
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: 25kg/bag.
