On December 25, the pilot production base project for Shangsaier’s thousand-ton-class photoresist resin materials and new optoelectronic materials was launched in the Huanggang Chemical Industry Park. Gao Weipeng, director of the Huanggang High-Tech Zone Management Committee, attended the event and delivered a speech. Wang Kaiwei, a member of the Party Working Committee and deputy director of the Management Committee of Huanggang High-Tech Zone, presided over the opening ceremony. The Shangcai New Photoelectric Organic Semiconductor Materials Industrialization Base project was signed and established in the chemical industrial park in June 2022. The new photoelectric organic semiconductor materials produced by this project have entered the supply chains of global leading manufacturers in this field; stable cooperative relationships have been established with domestic panel industry leaders such as CSOT and Tianma Microelectronics, as well as well-known companies from Japan and South Korea like Samsung and LG. On November 15, 2025, the company signed another investment agreement with Huanggang High-Tech Zone for a pilot production facility for kiloton-scale photoresist resin materials and new optoelectronic materials. The total investment planned for this project is 500 million yuan, and it will involve the establishment of five platforms: a platform for optimizing organic small-molecule fine chemical manufacturing processes and transitioning them to mass production, a platform for optimizing the purification processes of ultra-high-purity chemicals and transitioning them to mass production, a platform for optimizing the polymerization processes of high-performance resins and transitioning them to mass production, a platform for optimizing the formulations of organic optoelectronic functional materials and transitioning them to mass production, and a platform for pilot production quality control and diagnostic services. Once completed, the project will play a significant role in advancing the development and upgrading of the new materials sector in the high-tech zone, particularly in the field of high-end optoelectronic materials. It will provide important support for fostering new forms of productive capacity and building a modern industrial system.
