SZRH Film Technology Group is engaged in the research and development, production and sales of high-performance PI films. The main product series include thermal control PI films, electronic PI films, electrical PI films, etc., which are widely used in flexible circuit boards, consumer electronics, high-speed rail transit, and wind power generation. , 5G communications, flexible display, aerospace and other downstream fields, is one of the key basic materials in various industrial fields.
PI film is known as "gold film", the company has a number of core technologies
PI film is known as the "gold film" and is known as one of the world's best performance super engineering polymer materials. With the continuous in-depth research on PI film, in addition to being a traditional dielectric material, more application fields of PI film have emerged, such as precursor materials for high thermal conductivity graphite films, flexible display cover materials, etc., from dielectric materials Materials are expanded to functional materials and structural materials. Thanks to the drive of downstream market demand, new applications of high-performance PI films continue to emerge, expanding to new industries such as 5G communications, flexible OLED displays, and new energy vehicles. However, for a long time, most of the research results in the field of PI film in China have stayed in the laboratory stage. Due to insufficient mastery of production process technology, lack of production line integration and equipment design capabilities, there are few achievements in the industrialization or commercialization of high-performance PI films. .
SZRH has already established a R&D team with rich R&D experience, strong engineering and technical capabilities, and rich practical experience. The main R&D personnel have more than 10 years of experience. Based on more than ten years of research experience, the company has accumulated a large amount of laboratory research data. The company's engineering technology center was recognized as a provincial engineering technology research center. The company designs non-standard special equipment and the control system integration technology of the entire production line by itself, and has a deep grasp of the operation design calculation, special structure design, and process control integration of the production line. For new products, the company has the ability to design production lines based on formula characteristics, process flow and process parameters, and can independently and efficiently achieve new product development process requirements, greatly accelerating the efficiency of product industrialization. At present, the company has the ability to design special PAA resin formulations for multi-structure and nano-modification required for high-performance PI films. It has mastered core technologies such as PI molecular structure design and formulation design. It is good at accurately grasping the application characteristics of various products and targeted design. The main molecular structure, formula and process, etc., have practical experience in continuously developing new product formulas and realizing industrialization. As a pioneer in the domestic high-performance PI film industry, Ruihuatai completed the high-tech industrialization demonstration project of China`s National Development and Reform Commission’s "1000mm wide continuous biaxially oriented polyimide film production line" in 2010. Similar products have reached the international advanced level. Greatly promoted the localization of high-performance PI films. With the improvement of technical capabilities, the company continues to make breakthroughs in the research and development of new product formulations. Today, Ruihuatai has independently developed a series of products such as thermal control PI film, electronic PI film, and electrical PI film, and has become one of the most abundant high-performance PI film suppliers.
Break the international monopoly, products are recognized by customers
The strong technical strength has laid the foundation for the company's high-quality products. Based on mature formula design and other technologies, the company's product layout covers the three functional forms of PI film dielectric materials, functional materials, and structural materials. SZRH product categories include thermal control PI films, electronic PI films, electrical PI films, and aerospace applications. PI film, CPI film for flexible display and other categories, many of which break the market monopoly of foreign manufacturers. It has strong advantages in product variety, which is conducive to enhancing the ability to resist risks and laying a good market foundation for the company's business development.
Relying on advanced production technology and production process control capabilities, including high-precision and fully automatic resin synthesis procedures, mature casting and stretching technology, and online monitoring and control of the production line, the company's products have excellent quality stability and thickness deviation It can reach within ±5%, the continuous winding length can reach 5000 meters or more, and the number of joints per unit length is small, which can effectively meet the processing requirements of downstream customers and reduce their processing costs. Among them, the performance indicators of the company's corona-resistant PI film and other major products are equivalent to those of international advanced companies such as DuPont, reaching the advanced level of the industry. At the same time, the company's product costs are correspondingly lower. Therefore, compared with imported products, the company's cost-effective advantages are outstanding.
As one of the most abundant suppliers of high-performance PI film products in the world, SZRH's product sales accounted for about 6% of the world, breaking the technical blockade and market monopoly of foreign manufacturers on the domestic high-performance PI film industry and entering global competition Ranks. Many products developed by the company have filled the domestic gap and have been recognized by well-known domestic and foreign companies such as Siemens, Bombardier, CRRC, Avery Dennison, TESA, Polyonics, Shengyi Technology, Taihong Technology, Lianmao, and Tanyuan Technology. Two products of SZRH are listed in the "Made in China 2025 Key New Materials First Batch Application Demonstration Catalogue (2017 Edition)", the biaxially oriented PI film products won the gold medal of the 2012 China New Materials Industry Expo, and the colorless PI film products won the 2014 China Gold Award at the International New Materials Industry Expo.
