PSPI (photosensitive polyimide) market scale continues to expand PSPI photoresist is its end product

PSPI, the full name of photosensitive polyimide, is a high-end polyimide. It is an organic material with both imine rings and photosensitive genes in the polymer chain. PSPI has the characteristics of good photosensitivity, good thermal stability, and good mechanical properties, and has broad application prospects in aerospace, microelectronics, OLED display and other fields.

There are many types of PSPI. According to different structures and characteristics, they can be divided into ionic negative PSPI, ester negative PSPI, o-nitrobenzyl ester positive PSPI, polyisoimide positive PSPI, and self-sensitized positive PSPI. , chemically amplified PSPI, naphthoquinone azide type positive PSPI, etc. Overall, different types of PSPI have different outstanding advantages and disadvantages, and products with different characteristics need to be selected according to application requirements.

PSPI has a wide range of application fields, including aerospace, microelectronics, OLED display, etc. In the field of aerospace, PSPI can be used as aircraft heat insulation and insulating materials; in the field of microelectronics, PSPI can be used as electronic packaging glue; in the field of OLED display, PSPI can be used as photoresist for OLED display, which can effectively reduce the OLED displays the color difference of the device and improves its interlayer insulation. Benefiting from the rapid development of downstream industries, the PSPI market scale continues to expand. According to the “2023-2028 China PSPI (Photosensitive Polyimide) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that the global PSPI market size will reach US$420 million in 2022, a year-on-year increase of 19.6%.

PSPI photoresist, also known as photosensitive polyimide photoresist, is a PSPI end product. At present, my country’s PSPI photoresist industry is still in its infancy, has not yet achieved commercial application, and its demand is highly dependent on imports. In recent years, attracted by market prospects, my country’s PSPI photoresist research has become enthusiastic, and local companies and scientific research institutions have made many new progresses. In June 2022, Professor Teng Chao and his scientific research team independently developed PSPI photoresist, which means a new breakthrough in my country’s domestic photoresist. In the future, with in-depth research, the localization process of my country’s PSPI photoresist market will be accelerated.

The PSPI industry has high technical barriers, and the United States and Japan dominate the global PSPI market. DuPont, Futurrex, TORAY, Hitachi, Asahi Kasei, etc. are world-renowned PSPI manufacturers. In recent years, with the improvement of industry prosperity, the number of PSPI manufacturers in my country has continued to grow. Guofeng New Materials, Dinglong Co., Ltd., Wanrun Co., Ltd., Aoshen New Materials, Huicheng Technology, etc. are the main PSPI manufacturers in my country.

Industry analysts said that PSPI has excellent performance and good application prospects in the fields of microelectronics and OLED display, and will be accompanied by the development of downstream industries in the future. As the speed accelerates, the PSPI market space will be further expanded. my country’s PSPI industry started late and its demand is highly dependent on imports. In the future, with the in-depth research of local enterprises and the improvement of technological maturity, the market share of domestic PSPI in my country will increase.
