Founded in 1999, Kaiyu Limited is a high-tech company in China. We are professionally engaged in developing & manufacturing graphite new materials. We are also one of leading suppliers of natural crystalline graphite in China. Our plant is located in ShanDong province China, where is very famous for flake graphite mines.

By advanced grinding, floating, chemical purifying technologies, we produce all kinds of natural flake graphite, including microspheroidal graphite, expandable graphite, micronized graphite and high purity graphite. We developed Microspherical Graphite, which shape is like potato. This grade graphite has very high tap density and low specific surface area. We are good at controlling the content of trace elements (Fe, Cu, Mo, S), which makes our High Purity Graphite to be used as conductive additive in Alkaline battery. Our production capacity of Expandable Graphite is up to 1000mt per year, and it can be used as sealing materials and intumescent flame retardant. Using unique milling technology, we manufacture Micronized Graphite, and the finest particle size is 1.5 microns. We can also supply other graphite products, including flexible graphite sheet, graphite rods and graphite cloth.

We are always taking the quality of our graphite as the first position. Our plant obtained ISO9001 certificate, and we has advanced analyzing and test equipments. Under rigorous management system, our graphite products are very consistent & stable in quality. Most products are exported to Europe, USA, Japan, etc, and are popular among all customers.
