It is a large-scale intergrated enterprises that taking non-metallic mineral powder research and development .production and sales as one set and sales of talcum powder. Calcium carbonate, barium sulfate, magnesium hydroxide powder. In recent years, due to the extensive application of fire-retardant plastics and the increasing demand of flame retardants,peopole have higher requirment to new environment. The Company had set up tech cooperation with a number of universities and research institutes. Through the use of high-tesh surface treatment and modification of nano-technology, we jointly developed a new type inorganic flame-retardant powder:LHX-999. this technology leads the world and it is also the first case in China. The products have been exported far to Europe and America.
