Core Viewpoint - The liquid rubber industry in China is experiencing significant growth, driven by its superior properties and increasing demand in high-end applications such as medical devices and electronic equipment. The market size is projected to reach approximately 10.583 billion yuan in 2024, reflecting a year-on-year growth of 2.90% [1][6]. Industry Overview - Liquid rubber is a low-molecular-weight liquid oligomer that can form a three-dimensional network structure through chemical reactions, exhibiting physical and mechanical properties similar to conventional vulcanized rubber. It can be categorized into various types, including diene liquid rubber, olefin liquid rubber, polyurethane liquid rubber, liquid silicone rubber, liquid polysulfide rubber, and liquid fluororubber [2][4]. Industry Chain - The upstream of the liquid rubber industry includes raw materials such as organosilicon monomers, diene, olefin, catalysts, crosslinking agents, and production equipment. The midstream involves the manufacturing of liquid rubber, while the downstream applications span automotive, machinery, consumer goods, coatings, aerospace, and medical products [6][7]. - The continuous expansion of domestic organosilicon production capacity has significantly increased market supply, leading to a decrease in prices. As of September 2025, the price of organosilicon intermediates was 11,100 yuan per ton, down 20.71% year-on-year, which directly reduces production costs for liquid rubber [6][7]. Market Size - The liquid rubber market is expanding due to its excellent properties, with a projected market size of approximately 10.583 billion yuan in 2024, marking a 2.90% increase from the previous year [1][6]. Key Companies' Performance - The market concentration in the liquid rubber industry is relatively low but is gradually increasing. Companies like Hoshine Silicon Industry and Dongyue Silicone Material are notable players, with Hoshine leveraging its full industry chain advantage and Dongyue establishing a strong position in the fluorosilicone materials sector. Both companies are investing in R&D to enhance product quality and performance [7][8]. - Hoshine Silicon Industry reported a revenue of 9.775 billion yuan in the first half of 2025, a decrease of 26.34% year-on-year, with a net profit of -397 million yuan, down 140.60% [8]. - Dongyue Silicone Material achieved a revenue of 2.327 billion yuan in the first half of 2025, a decline of 14.98% year-on-year, with a net profit of 42 million yuan, down 35.30% [8]. Industry Development Trends 1. **Continuous Technological Innovation**: The industry is focusing on developing high-performance, environmentally friendly, and cost-effective liquid rubber products, with an emphasis on special functional products for various applications [9]. 2. **Expanding Market Demand**: The technology is evolving towards high-end applications, including aerospace seals and 5G chip packaging, with companies like Hoshine and Xingfa Chemical leading innovations in these areas [9][10]. 3. **Integration of the Entire Industry Chain**: Leading companies are integrating their operations from raw materials to deep processing, enhancing their competitive edge and reducing costs. There is also a push for international expansion, with companies like Dongyue exporting products to multiple countries [10].
