Properties:

No taste or poison. Specific gravity: 1.65-2.00, Soluble in chloroform, dilute, benzene, hardly soluble in carbon tetrachloride ethanol and ethyl acetate; insoluble in water. No hygroscopic. 
Application:

It is a super accelerator for NR, SNR, IIR, IR, SBR, NBR, EPDM and their latex. The cure rate of ZDPC in latex is the lowest comparing with other dithiocarbamates. Also, owing to its scorchy, the product is seldom used alone, mainly as secondary accelerator for thiazoles and sulphenamides. ZDPC produces no pollution or poison, easily disperses, so suitable in use of medical necessities, latex products, white or colored products, transparent products and food and beverage containers. 
Package:

25kg N.W./bag, in plastic fabric laminated kraft bags lined with plastic bags.
