填补空白！康辉新材，高性能光学膜技术突破

Core Viewpoint - Kanghui New Materials Technology Co., Ltd. has achieved significant breakthroughs in the production of polarizer protective base films, reaching advanced industry levels in both yield and quality, thus ending the long-standing market monopoly by imported products in the high-end polarizer protective base film sector [2][3]. Group 1: Company Achievements - Kanghui New Materials has successfully achieved stable mass production of polarizer protective base films, with monthly shipment volumes nearing 10 million square meters, making it the leading domestic enterprise in this field [3]. - The products have gained high recognition from downstream customers, leading to a continuous increase in order volumes and successfully penetrating the domestic mainstream polarizer market [3]. Group 2: Industry Context - The BOPET polarizer protective base film is a critical optical material in the polarizer manufacturing process, with stringent requirements for film flatness, defect control, and thermal stability, directly impacting production efficiency and product quality for downstream enterprises [2]. - Historically, the high-end polarizer protective base film market has been dominated by Japanese and Korean companies, creating high technical barriers that forced domestic polarizer manufacturers to rely on imports, facing challenges such as high procurement costs and unstable supply cycles [2]. Group 3: Strategic Implications - The breakthroughs achieved by Kanghui New Materials not only validate its R&D capabilities and manufacturing strength in the high-end optical film sector but also promote the deep extension of China's display industry into upstream core material segments, providing essential material support for the high-quality development of strategic emerging industries such as new displays and consumer electronics [3].
