由厚到薄！三利谱从“一无所有”到“自主可控”

Core Viewpoint - The company Sanli Pu has successfully transformed from a reliance on imported polarizers to becoming a leader in the global market, capturing 80% of the market share alongside two other domestic firms, showcasing a journey from "nothing" to "self-sufficiency" in the polarizer industry [2][3]. Group 1: Company Development - Sanli Pu was established in 2007, starting from scratch with no technology, equipment, or talent, and faced significant challenges due to foreign companies' refusal to share technology [3][4]. - The company built its first full-process polarizer production line in Putian, Fujian, after three years of development, marking a significant breakthrough from having no production capabilities [3][4]. - By 2010, the company recognized the need for a wide-format production line for the panel industry and managed to build it for only 1 billion yuan, which was one-seventh of the cost of importing Japanese equipment [4]. Group 2: Material Localization - Sanli Pu began to extend upstream in 2018, actively supporting domestic suppliers to overcome the high technical barriers in key materials such as base films, adhesives, and dyes, which were previously 80% reliant on imports [5][6]. - The localization rate of raw materials has exceeded 50%, with expectations to reach 80% by next year, potentially reducing costs by an additional 15% to 20% [6]. Group 3: Technological Innovation - The company has achieved significant advancements in reducing the thickness of polarizers, developing a 35-micron ultra-thin polarizer that is suitable for emerging applications like foldable screens and VR glasses [6][7]. - Sanli Pu has developed a high-durability dye-based polarizer for automotive displays, breaking the long-standing monopoly of Japanese companies in this sector [7]. - The company has also made strides in the VR/AR field with its Pancake optical film technology, addressing critical challenges in optical design for next-generation near-eye display devices [7]. Group 4: Financial Performance - In the first half of 2025, Sanli Pu achieved a revenue of 1.68 billion yuan, marking a year-on-year increase of 41.97%, with the second quarter revenue reaching 874 million yuan, reflecting strong growth momentum [7].
