Properties: White powder (granule). The density is 1.24. Soluble in CS2. benzene, chloroform, alcohol, diethyl ether,insoluble in water and low concentration alkali. Good storage stability.

Application: Used for NR, IR, SR, SBR, NBR, EPDM and their latexes. A fast curing primary or secondary effective ultra-accelerator for natural and synthetic latex form compounds. Can be used advantageously for dipped, spread, and cast goods. Similar in pro

Application: Used for NR, IR, BR, SBR, NBR, HR, EPDM and natural & synthetic latexes. Stronger accelerating power than TMTD. Strong resistance to scorching. In its handling, care should be operated, because of its increase activation and strong tendency to

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 (foa
