Chan Ye Xin Xi Wang·2025-07-01 01:16Core Viewpoint - The polyurethane sealant industry in China is facing significant challenges due to the high technical barriers and monopolization of the high-performance market by foreign companies, with over 90% of the high-end market dominated by international products. However, advancements in domestic technology and innovation are emerging, particularly from research institutions like Zhengzhou University, which have made breakthroughs in developing competitive products [1][7][8]. Group 1: Industry Definition and Characteristics - Polyurethane sealants are classified as high-grade elastic sealants, known for their excellent wear resistance, low-temperature flexibility, and good adhesion properties. They have a lifespan of 15-20 years and are suitable for dynamic joints, although they have limitations such as poor heat resistance and water resistance [2][7]. - Low-modulus polyurethane sealants are characterized by being single-component, non-flowing, solvent-free, and environmentally friendly, making them suitable for high-movement joints in construction applications [4][5]. Group 2: Current Industry Status - The demand for polyurethane sealants is increasing due to rapid urbanization and growth in the construction and automotive sectors. However, the technology for high-performance polyurethane sealants remains largely monopolized by foreign companies, limiting domestic development [7][8]. - From 2016 to 2024, China has filed a total of 589 patents related to polyurethane sealants, with a peak of 91 patents in 2019, indicating a shift from imitation to original innovation in the industry [8]. Group 3: Industry Chain - The polyurethane sealant industry chain includes upstream materials such as isocyanates and polyols, midstream production of sealants, and downstream applications in construction, transportation, and electronics [10]. - In the construction sector, polyurethane sealants are primarily used for waterproofing, sealing, insulation, and soundproofing, with increasing market demand driven by the industry's growth and environmental requirements [12]. Group 4: Competitive Landscape - Major companies in the polyurethane sealant industry include Chengdu Silica Technology Co., Ltd., Beijing Gaomeng New Materials Co., Ltd., and Hubei Huitian New Materials Co., Ltd., among others. These companies are focusing on research and development to enhance their product offerings and market presence [14][17]. - Beijing Gaomeng New Materials has a strong market position with a diverse product range and advanced production capabilities, including 37 production bases and a focus on high-performance adhesive materials [20][21]. Group 5: Industry Development Trends - The future of the polyurethane sealant industry in China is expected to focus on technological innovation, expansion of application scenarios, and environmentally friendly practices. The demand for high-precision sealing materials in electronics and aerospace is also anticipated to grow [24].
