Sieve residue (150 μ m) ,% ≤ 0.50

Property: White or grayish white powder, molecular weight 228.30, relative density 1.27-1.33, soluble in dimethylformamide and acetone, slightly soluble in benzene, carbon disulfide, chloroform, insoluble in xylene, carbon tetrachloride, alcohol, and water.

Usage: This product is a medium speed vulcanization accelerator suitable for natural rubber, chloroprene rubber, styrene butadiene rubber, nitrile rubber, etc. When used with sulfur donors in natural rubber and styrene butadiene rubber, it can shorten the vulcanization time, improve the durability of the vulcanizate, and do not spray frost. It can be used as a second accelerator in the natural vulcanization system of chloroprene rubber and EPDM rubber. This product is not suitable for products that come into contact with food. Mainly used for latex products, wires and cables, water-based materials, and general industrial products.

Packaging: Composite paper bag, lined with plastic film bag, net weight of 25 kilograms.
