In November 2017, Times New Materials' annual output of 500 tons of polyimide film production line has been commissioned and optimized. At the beginning of 2018, Damai's new plant is expected to open a production line of 600 tons and include advanced PI research and development. Expansion of the building. In May 2018, the company independently developed and started mass production in Zhangzhou Detai Electronic Technology Co., Ltd.
Since last year, information about PI films has jumped into people's sights. It is well known that in the manufacturing process of OLEDs, the substrate is generally a high temperature resistant polymer due to the need to sputter electrodes or TFT materials on a flexible substrate. The PI film has excellent properties such as high temperature resistance, electrical insulation, adhesion, and radiation resistance. Therefore, the most used substrate is high temperature resistant polyimide (PI) material.
Global PI film industry overview
At present, PI film manufacturers have developed a variety of commercial high-performance PI films. Due to the high level of research and development and high difficulty, the current PI film industry is Dupont, Ube, and Kaneka. Japan's Mitsubishi Gas MGC, South Korea's SKCK-OLONPI and Taiwan's Damai as major producers.

The future development trend of PI ultra-thin film
PI ultra-thin film is a kind of high-performance polymer film material developed in the past 10 years. Its excellent comprehensive performance quickly established its leading position in the organic film material family. At present, the development direction of PI ultra-thin film is mainly reflected in Two aspects: First, the ultra-thinning of standard Kapton film; the other is the development and development of functional PI ultra-thin film.
For the former, the excellent thermal and mechanical properties of the Kapton film itself ensure the stability of its performance during the ultra-thinning process. The main technical bottleneck is more in the optimization and adjustment of the preparation equipment and membrane process parameters. For the PI ultra-thin film, its performance is not only closely related to equipment and process, but also the molecular design of the resin structure and the research of new synthetic methods play a vital role. How to ensure the special functions, It is a challenging research topic to maintain the inherent mechanical properties and thermal properties of PI films. It is also a major research topic in the future.
Ultra-thin PI film has broad application prospects in the modern industrial field. Foreign countries attach great importance to the development and development of such materials, and there have been batch products.
Overview of domestic PI film product development
China is one of the earliest countries in the world to develop PI film. In the 1970s, the former Ministry of Machinery and the Ministry of Chemical Industry led the Shanghai Institute of Synthetic Resins on the basis of the research results of the Changchun Yinghua Institute of the Chinese Academy of Sciences and the East China Institute of Chemical Technology. Referred to as Shanghai Institute and the First Electrical Machinery Research Institute of Beijing Electric Appliance Research Institute (now Guilin Electric Science Research Institute Co., Ltd., referred to as Guilin Electric Power Research Institute), respectively, using the impregnation method and the rogue method to manufacture PI film, Shanghai Innovation Plastics Factory first put into production year Producing 5t impregnating PI film, Guilin Electric Power Research Institute and Tianjin Insulation Material Factory, East China Institute of Chemical Technology collaborated to develop a process route for the production of benzene-type PI film by rogue method. In 1978, Guilin Institute of Electric Power and the Seventh Design Institute of Machinery Department Working together, we developed a special equipment for biaxially oriented PI film. In 1993, Shenzhen Xingbang Electrical Equipment Co., Ltd. completed the first domestic industrial production line of 60t/y and 650-700mm wide biaxially oriented PI film. Domestically, Shenzhen Ruihuatai, Fuyang Huajing, Shandong Wanda, Wuxi Gaotuo, Guilin Electric Power Research Institute, Jiangyin Tianhua and other 10 companies adopt rogue bidirectional stretching workers. PI film manufacturing, industrial development sequentially biaxially stretched film of PI.
At present, there are about 50 PI film manufacturers of different sizes in China, of which about 80% are manufactured by rogue process, and only a few manufacturers use biaxial directional process. The domestic PI film product width is 1040mm, and the single production line capacity is basically 200t. /y or so. According to the application of different terminal electronic products, PI film thickness specifications can be divided into 7.5μm, 12.5μm, 25.0μm and thick film, in which mobile phones, cameras and other handheld electronic products use 12.5μm or thinner PI film. For general electronic products, cars, laptops and cover films use PI films with a thickness of 25.0 μm, while reinforcing plates use thicker PI films.

The future development of PI film in the optoelectronic industry
The downstream application of PI film is extensive, and the demand for products is large. Due to the diversification of consumer electronic products, the life cycle is becoming shorter and shorter, resulting in less product quantity and high customization, which makes domestic related enterprises actively participate in the industry and conduct niche competition. For this reason, we focus on the 10 years of FILM&TAPE EXPO in the optoelectronics industry to create a dedicated platform for the PI film industry. At that time, hundreds of well-known companies will bring their R&D new products to the 2018 Shenzhen International Film and Tape Exhibition. This time, 350+ film and The well-known enterprises at home and abroad in the tape industry will focus on displaying various functional films and adhesive products, providing a one-stop supply and demand platform from materials, solutions to R&D and manufacturing, focusing on optoelectronic manufacturing, mobile phone manufacturing, home appliance manufacturing, printing and packaging. Medical and automotive solutions, from touch screens / LCD monitors / mobile phones / home appliances, backlight modules, photovoltaic / lithium batteries, printing and packaging, flexible circuit boards, consumer electronics, professional buyers in the automotive industry, insight into new trends, Realize zero barriers between the supply and demand sides.
The exhibition will also be accompanied by the famous "International Touch and Display Exhibition" (CTOUCH & DISPLAY), 3D Curved Glass Manufacturing Technology and Application Exhibition, Camera Module and Machine Vision Technology Exhibition, South China International Coating and Die Cutting The Technology Exhibition (ICDE) will be held in the same place at the same time, with five exhibitions and one-card campaign. The exhibition will cover nearly 1,000 well-known brands, attracting nearly 40,000 consumers from home and abroad in consumer electronics/3C manufacturing, automotive electronics manufacturing, and automation. Managers and procurement decision-makers can cooperate with each other. During the visit, the audience can also learn about the new trends and technical applications of the industry through factory visits, technical training, hot topic seminars and industry summit forums, and with exhibitors and The peers discuss the hot topics in the industry.
