Properties:
Yellowish bitter nontoxic powder with slightly stinking odor, the specific gravity of 1.42-1.52, and melting point of above 170°C. Freely soluble in ethyl acetate, acetone, sodium hydroxide as well as the dilute sodium carbonate, soluble in ethanol, very slightly soluble in benzene, and insoluble in water and gasoline with stable storage.
Uses:
It is a semi-super accelerating agent, widely used in natural rubber and synthetic rubber with a wide sulphidizing range for tyres, rubber shoes and other industrial rubber products, capable of being used solely or with thio-carboxylamine salts, thiuram, carbamidine and other basic accelerating agent. .It may happen early curing when it work with furnace carbon black. It is easy to disperse, and offers no color change and pollution. Because of bitter taste, it can’t be used in food rubber.
Packing:
Composite bag, Net wt. 25kg.
