Characters: white powder. Relative density: 1.10. Soluble in acetone, ethanol, soluble in water, insoluble in gasoline. Hygroscopicity.
Uses:promote the effectiveness of this type of accelerant burned low and anti-poor performance, so on the diene rubber has been rarely used, but in special circumstances, such as the use of thiuram sulfide and other sulfur-donor vulcanization, the product active agent with the role of thiourea on the neoprene vulcanization accelerator is a unique performance, can be obtained tensile strength, hardness, compression good performance such as chloroprene rubber vulcanization. This product is compared with the NA-22, scorch and curing are fast, but the curing flat is better. Dispersion, not bloom. Amount of large, high temperature curing can be especially suitable for continuous vulcanization extrusion products, this product is used butyl rubber accelerator, EPDM rubber vulcanization agent will live. For natural rubber, neoprene, nitrile rubber and styrene butadiene rubber antioxidant. Generally used for manufacturing industrial products. Special wire, sponge products.
Packing:25kg plastic woven bag, Paper bag, kraft paper bags.
Storage:should be stored in a cool dry, well-ventilated place. Packaged products should avoid direct sunlight, valid for 1 year.
