Properties: white to light yellow crystalline powder. Relative density 1.06. soluble in alcohol, soluble in ethanol, difficult to dissolve in ether, insoluble in water. Slightly soluble in diethyl ether. Insoluble in water.
Use: This product is a rapid vulcanization accelerator for neoprene, the performance is similar to ETU and DETU, suitable for rubber with low vulcanization temperature, and the physical properties of the product are better. It also promotes the commercialization of natural rubber, styrene-butadiene rubber, butyl gum and EPDM rubber. It is also an anti-ozone agent for natural gum, chloroprene gum, nitrile gum and styrene-butadiene gum. No pollution, no discoloration. Mainly used in wires, industrial products and sponge products.
Packing: 25kg plastic woven bag, paper-plastic composite bag, 25kg drum.
Storage: Should be stored in a cool, dry, well-ventilated place. The packaged products should avoid direct sunlight, and the stacks between the trays cannot be stacked, overlapped or the temperature is ultra-high 3S? C will cause the product to be abnormally compressed, and the validity period is 1 year.
