As we enter mid-August, the chemical new materials sector is seeing a flurry of developments across multiple dimensions, from corporate performance in the capital markets and patent innovations to product pricing and market supply-demand dynamics, all presenting a complex yet opportunity-rich landscape.

　　In the capital market, on August 11, Runcheng Materials' stock price closed at 33.02 yuan, with a 4.10% increase, and its rolling price-to-earnings ratio dropped to 59.10 times, hitting a 61-day low, with a total market capitalization of 5.939 billion yuan. Its first-quarter report for 2025 showed revenue of 322 million yuan, up 7.93% year-on-year, and net profit of 24.1099 million yuan, up 21.42% year-on-year. On the same day, Yuanxiang New Materials' stock price rose by 4.6% to 44.78 yuan, with trading volume exceeding 210 million yuan. As a specialized, refined, and innovative enterprise, the company focuses on the research, development, production, and sales of organosilicon materials, with products widely applied in electronics, new energy, healthcare, and other fields. Fund flow data shows that on the same day, net inflow of main funds reached 7.2927 million yuan, with a cumulative net inflow of 12.197 million yuan over the past five trading days.

　　In terms of patent innovation, information from the National Intellectual Property Administration indicates that Guangdong Lier New Materials Technology Co., Ltd. applied for a patent titled “A Secondary Branched Epoxy-Modified Organic Silicon Resin and Its Preparation Method and Application” (publication number CN120441843A) in June 2025. This invention enhances the low-temperature toughness of thermosetting epoxy resin by introducing branched structures and “flexible Si-O-Si” molecular chains, and improves moisture and heat resistance by leveraging the hydrophobic properties of organosilicon. It is expected to achieve breakthroughs in the field of flexible die-cut circuit board cover films. Concurrently, Three Gorges Jinsha River Chuan Yun Hydropower Development Co., Ltd. applied for a patent titled “A waterproof organosilicon gel and its preparation method” (publication number CN120442056A). By adding composite micro-nano fibers and bio-waterproofing agents, the waterproofing and adhesive properties of the organosilicon gel are significantly enhanced to meet the application requirements of instruments and meters in rainy environments.

　　Looking at market supply and demand, the organosilicon market is in flux. Five major organosilicon giants, including Zhejiang Xinan and Shandong Dongyue, have simultaneously suspended trading, with raw rubber and 107 adhesive ceasing to quote prices, leaving the market in a state of “no price, no market.” Four monomer production facilities in Shandong, Zhejiang, and Xinjiang are undergoing concentrated maintenance, affecting over 1 million tons of production capacity, causing the industry's operating rate to plummet. As a result, DMC spot prices have surged, with mainstream transaction prices exceeding 12,700 yuan per ton, up 500 yuan per ton from last week. Heisheng raw rubber production has been scheduled until the end of August, exacerbating supply shortages. In the industrial silicon market, although the downward trend in spot prices slowed this week, as of August 8, the benchmark spot price was 8,705 yuan per ton, down 2.38% from August 1. However, the main futures contract bottomed out and rebounded, with the latest transaction price at 8,710 yuan per ton, representing a weekly increase of 2.53%. On August 11, influenced by macroeconomic policies and related commodity trends, the main industrial silicon contract 2511 closed at 9,000 yuan, up 4.83%. However, increased supply from the main production areas in Southwest and Northwest China, ongoing inventory buildup in the industry, and rising export volumes are exerting pressure on domestic prices. ?

　　Overall, the chemical new materials industry saw notable developments in corporate growth and technological innovation during the mid-August period. However, issues such as market supply-demand imbalances and price volatility remain prominent. Companies must closely monitor market dynamics, strengthen innovation and cost control to seize opportunities in this complex environment.
