Properties: White powder. Little bitter. Density is 1.42-1.43. Soluble in water，alcohol, ethylene glycol and pyridine, do not dissolve ether, benzene, chloroform and petroleum ether. No pollution to final products. Stabilization storage
Application:: The product can be used to chloroprene rubber, Epichlorohydrin rubber, chlorinated polyethylene, etc., are particularly suited to non-curing system of the chlorine-butylamine Hopewell accelerator. Can often 100-500 oC , with the right selection system can be the best rapid curing, and the whole parade security. Its products vulcanized high tensile strength, permanent deformation small for W (54-1 type polychloroprene), a non-curing system into effect significantly. It usually with zinc oxide and magnesium oxide together with the use, mainly for industrial products, and coating lines, shoes and other clothing chloroprene rubber products.
Packaging: 25kg plastic woven bag, paper with plastic film bag, Kraft paper bag.
Storage: To keep the bags tightly closed in a cool, well-ventilated place at 25 max, to place the goods on the dry wooden shelf at a height of 20cm min. And to avoid from moisture, sunshine, light and fires. The recommended max.shelf life is 2 years.
