Kaiyu Industrial (Hk) Limited

Founded in 1999, Kaiyu Limited is a high-tech company in China. We commit ourselves to 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 ores. At present we have 128 employees and 15 professional engineers.

By advanced grinding, floating, chemical purifying technologies, we produce all kinds of natur
al flake graphite, including spherical 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. It is used as negative raw materials for Li-ion secondary battery and can be applied in other industries. 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 are always taking the quality of our graphite as the first position. Our plant obtained IS
O9001 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.
  
We make promise to the customers:
Best quality, Quick response, Reasonable price and Excellent s
