About KBC

KBC Co., Ltd. is mainly engaged in the R&D, production, and sales of advanced carbon-based composite materials and products. KBC is a high-tech enterprise with independent research and development capabilities and continuous innovation abilities. The company is committed to providing customers with high-performance and cost-effective advanced carbon-based composite material products and complete solutions. It is an advanced carbon-based composite material manufacturing enterprise selected as one of the first batch of "little giant" enterprises with special expertise and new technology by the Ministry of Industry and Information Technology. The company is also a national intellectual property advantage enterprise, an advanced unit for the development of non-public ownership economy and small and medium-sized enterprises in Hunan Province, and a green factory in Hunan Province. The company successfully landed on the Sci-Tech Innovation Board on May 18, 2020, becoming the third listed company on the board in Hunan Province and the first listed company in the civil use carbon/carbon composite materials industry in the Shanghai and Shenzhen stock markets.


Since its establishment, the company has made significant breakthroughs in the low-cost production and preparation, diversified product types, and independent equipment design of advanced carbon-based composite materials, relying on independent research and development and continuous innovation. The company has mastered the core technology of low-cost preparation of advanced carbon-based composite materials and achieved mass production. KBC's advanced carbon-based composite material crucibles, guide tubes, insulation sleeve, and other products have been promoted and applied in the thermal field system of polycrystalline silicon manufacturing, and have gradually replaced and upgraded high-purity isostatic graphite products. The overall technology and industrialization capabilities of KBC are at the forefront of the industry.


KBC aims to develop the key technology of low-cost preparation of advanced carbon-based composite materials. We has organized a core research and development team covering multiple disciplines such as materials, textiles, non-woven fabrics, machinery, and electricity. We has obtained 112 patent authorizations and exclusively or as the first drafting unit, led the formulation of 5 national industry standards. We has undertaken important research and development projects such as the Major Project of the 863 Program of the Ministry of Science and Technology, the Technology Innovation Fund for Small and Medium-sized Technology-based Enterprises, and the Special Project for High-tech Industrialization of the National Development and Reform Commission.


In the future, KBC will continue to increase its technological innovation efforts, develop and expand related diversified products in the market, and research, develop, and sell products used in the fields of semiconductors, high temperature, wear resistance, and corrosion resistance. KBC will continue to enrich the types of its main products and maintain its advantageous position in the market competition.
