On August 13, Kaisheng science and technology, affiliated to China Building Materials Group, successfully developed 30 micron flexible folding glass, and started industrial production on August 25, creating China's first in the field of new glass materials, becoming the only enterprise in the world that can independently develop 30 micron flexible glass through the whole process of raw and post-processing, further enhancing China's competition in the field of new glass materials in the world Power of contention and right of speech.

With the rapid progress of 5g, Internet +, AI and other information technologies, the demand for human-computer interaction is increasing, and flexible display has become the power engine leading a new round of changes in the display industry. Since 2019, many terminal manufacturers have invested heavily in the field of folding to develop new products. As the core material of foldable display devices, the research and production of flexible glass is very difficult, which has become the commanding point of global display industry technology competition and future development.

Kaisheng technology, a subsidiary of China Building Materials Group, utilizes its scientific research and industrialization capabilities in flexible touch glass, integrates the advantages of its Bengbu Institute, Bengbu optoelectronics and Kaisheng Technology Co., Ltd., independently develops high-strength flexible glass formula and new technologies of thinning, strengthening, cutting and molding, and produces ultra-thin flexible glass with 30-70 micron thickness The products have been bent for 200000 times without damage, and the bending radius is less than 1.5mm. The main performance indicators and parameters are in the leading level in the industry. It has formed the only national production ultra-thin flexible glass industry chain covering "high-strength glass ultra-thin thin-film-high-precision post-processing", breaking the foreign monopoly and ensuring the security of China's information display industry chain from the source.

The success of 30 micron flexible foldable glass is another major "neck sticking" innovation achievement in 2020 after China Building Materials Group produced the world's thinnest 0.12 mm ultra-thin glass in 2018 and the production line of float 8.5 generation LCD glass substrate with independent intellectual property rights in 2019.

China Building Materials Group will persist in promoting the deep integration of innovation chain and industrial chain, accelerate the application and promotion of original innovation achievements, strive to achieve the production capacity of 1.2 million pieces of flexible glass by 2021, and actively participate in the international market competition. At the same time, we will continue to carry out basic research and application basic research, strengthen the research and development of flexible glass with the size of 25 μ m and below, and accelerate the forward-looking layout of special flexible glass such as radiation resistance, so as to make new contributions to the development of digital economy and high-quality economic development in China.
