Xuguang Chemical Co., Ltd now has four acetylene black production lines with annual capability of 8000MT acetylene black, 100,000 cylinders of acetylene gas, which is one of the biggest acetylene black production base. Acetylene black is used extensively for industry of dry battery, radio components, conductive rubber, plastic, silicone rubber, conductor, cable shielding material, paint, lubricants etc. Our 0, 50% compressed powder products won the silver metal of product quality in China acetylene black industry. With high conductivity, low resistivity, high purity, the products have been sold to USA, Japan, southeast of Asia and so on and has very good reputation both in domestic and overseas market.

Acetylene black is made from calcium carbide. It has the following features: light mass with small specific gravity; large surface area with strong absorption; stable chemical property; good surfaces activity with high conductivity; high purity with low ash and volatile.
