Recently, China`s Polyimide Film (PI Film) industry leader, SZRH Film Technology Group successful IPO, will use the power of the capital market to bring strong support for the localization of China`s PI film industry and further break the international industry giant`s Monopoly in the field of PI film.
Film is one of the earliest products form of polyimide, mainly used for H-class or C-class insulation (H-class and C-class are heat-resistant grades of insulating materials). Because PI film has high oil resistance, temperature resistance and low dielectric loss and other excellent comprehensive properties, it has the reputation of "gold film"; it can be used as cable insulation material, heat insulation material, radiation protection material, recording carrier material, etc. Therefore, PI film is widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras, electrical instruments and other fields. It is an irreplaceable key material in the power, electrical, microelectronics and precision machinery industries.
With the development of technology and the promotion of downstream demand, since the 21st century, more applications of PI films have been developed, such as precursor materials for high thermal conductivity graphite, flexible display cover materials, etc. At the same time, the demand for foundry production in the electronics industry chain is gradually released. Countries such as China and South Korea seize the opportunity of industrial transfer. The high-end manufacturing industry has developed rapidly, and the PI film industry has risen accordingly.
As a pioneer in the field of high-performance PI films in China, Ruihuatai completed the acceptance of the high-tech industrialization demonstration project of the National Development and Reform Commission`s "1000mm wide continuous biaxially oriented polyimide film production line" in 2010, forming a special resin preparation To the complete preparation technology of continuous biaxially stretched film production, similar products have reached the international advanced level.
Master the core technology to accelerate the localization of PI films
After 15 years of development and precipitation, SZRH has now become one of the few high-performance PI film manufacturers in China that has a complete set of core technologies such as formulas, processes and equipment, and has successfully developed thermal control PI films, electronic PI films, electrical PI films, and aerospace The use of PI films and other series of products broke the technological blockade and market monopoly of advanced foreign manufacturers on China's high-performance PI film industry, and entered the ranks of global competition.
In addition, with its outstanding product strength, SZRH's two products have also been included in the "Made in China 2025 Key New Materials First Batch Application Demonstration Catalog (2017 Edition)", and the biaxially oriented PI film products won the 2012 China New Material Industry Expo Gold Award, colorless PI film products won the 2014 China International New Materials Industry Expo Gold Award.
