Established in 1999, Kaiyu Limited is a high-tech company in China. We are professionally engaged in developing & manufacturing graphite and carbon new materials. We are also one of leading suppliers of natural graphite and synthetic graphite in China.

By advanced grinding, floating, chemical purifying technologies, we produce all kinds of natural flake graphite, including microspherical graphite, expandable graphite, micronized graphite and high purity graphite. We developed Spherical Graphite, which shape is like potato. This grade graphite has very high tap density and low specific surface area. 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 Micronzied Graphite, and the min. particle size is 1 um. We can also supply other graphite & carbon products, including flexible graphite sheet, graphite rods, graphite cloth and carbon fiber powder, etc.

We are always taking the quality of our graphite as the first position. Our plant is ISO9001 certificated, 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.
