China Lekai Group Co., Ltd

1、 China Lekai Group Co., Ltd. (hereinafter referred to as China Lekai) is a modern enterprise that integrates research and development, manufacturing, and service in the fields of digital printing imaging materials, high-performance film materials, and image information materials. It is the largest research and production base for printing imaging materials and image information materials in China, A large-scale research and development and production base for high-end optical films and deep processing products used in flat panel displays in China, as well as a research and production base for special photosensitive materials and special films in China. Having two well-known Chinese trademarks, "Lekai" and "Huaguang", "Lekai" has been awarded the first batch of "China Export Brand" titles in the country, and "Huaguang" is the first brand of printing materials in China. By the end of 2019, Lekai had total assets of 12 billion yuan and more than 8500 employees, including more than 3300 academicians, doctors, senior engineers and various professional technicians of the CAE Member. We have 22 wholly-owned subsidiaries at all levels, 10 holding subsidiaries, 5 directly affiliated units, and 8 participating companies, including 2 listed companies. The main production bases are distributed in Baoding, Hebei, Nanyang, Henan, Hefei, Anhui, Shenyang, Liaoning, Shantou, Guangdong, Tianjin, Shanghai, Jiangsu, Changzhou, and other places. At present, China Lekai Research Institute is a "technology incubator" laying out advanced technologies in new materials. The film based business unit focuses on industrial research and development of optical display new materials. In 2019, Lekai Group was shortlisted for the 33rd China Top 100 Electronic Information Companies. Optical PET film (polyester film) and TAC film (cellulose acetate film) have successfully built Lekai's development foundation in the field of optoelectronic displays, It has filled the gap in the key raw material field of China's upstream flat panel display industry, and the products have been successfully applied to LCD display products of well-known domestic and foreign brands such as Hisense, Haier, Changhong, TCL, and Samsung, LG. Polarizers use TAC film to fill the domestic gap, as a characteristic product of the display industry, filling an important link in the complete display industry chain of Hebei Province. The above-mentioned technological advancement process involves the introduction of foreign experts. 2、 Next, China Lekai will continue to introduce foreign technical experts or teams around the development of high-performance PVB films, optical TAC films for high generation line polarizers, air dehumidification film projects, and low haze AG film projects. 1. The development project of high-performance PVB membrane has a development cycle of 5 years, including research on PVB resin synthesis and film forming process technology, engineering research, and will continue to rely on the technical guidance of one foreign expert to carry out work. 2. The development cycle of the optical TAC film preparation technology project for high generation line polarizers is 5 years, and the research content includes formula development, casting process technology research, and engineering research. With the progress of the project, in addition to one foreign expert currently introduced, top technical teams in the foreign industry will continue to be introduced for full technical guidance. 3. The research and application product development project of air dehumidification membrane technology continues to develop the air dehumidification membrane project, achieving a coating microstructure with separation and selection functions, and meeting the application requirements of high water vapor permeability and low permeability coefficient of other mixed gases. By designing and researching the system of air dehumidifiers, the product has the advantages of high dehumidification efficiency and low energy consumption. At the same time, establish a set of application testing platforms to promote the industrialization process. 4. The low haze AG film development project actively introduces experts to guide the project team in designing the low haze AG film technology route, conducting experiments, establishing and improving testing methods, verifying application performance, and completing the development of low haze AG film coil samples to meet application performance requirements. Actively carry out tracking and analysis of international advanced technology and information, and provide information on technological development and market dynamics.
