On October 10, 2025, Yongxiu County in Jiangxi Province reported that as the core gathering area of the domestic organic silicon industry, Yongxiu County is promoting the transformation of industrial clusters towards high-end and intelligent industries through the "Industrial Brain" digital platform and breakthroughs in bio based material technology. According to the latest data from the Yongxiu County Bureau of Industry and Information Technology, from January to September 2025, the scale of the county's organic silicon industry will exceed 30 billion yuan, a year-on-year increase of 18%. Among them, the proportion of high-end products will increase to 42%, an increase of 12 percentage points from 2024.


Biobased Materials: A Green Revolution to Break Free from Oil Dependence
In July 2025, the world's first 10000 ton bio based silicone rubber production line will be put into operation in Shandong, using rice husk to produce highly active silane technology, with costs approaching those of petroleum based routes. This breakthrough quickly spread to the Yongxiu industrial cluster. Taking Cabot (Yongxiu) Company as an example, its newly built 5000 tons/year bio based white carbon black project has entered the trial production stage. The product is applied to photovoltaic film and lithium battery separator, with a carbon footprint reduced by 35% compared to traditional processes.


Biobased materials are not only a demand for environmental protection, but also the key to breaking the curse of the 'methanol metal silicon' price linkage, "said an analyst from China Research Institute PwC. In September 2025, Hesheng Silicon Industry officially signed a contract with a Brazilian chemical giant for a sugarcane based methanol project. It is expected to provide stable and low-priced raw materials for Yongxiu Enterprises after it is put into operation in 2026, and the cost per ton is expected to decrease by 800 yuan.


Industrial Brain: Digital Technology Reconstructs the Industrial Chain
The organic silicon "industrial brain" platform invested 40 million yuan in Yongxiu County has become a core tool for industrial upgrading. By integrating industrial operating systems and industrial apps, the platform achieves data sharing across the entire industry chain: upstream Blue Star Spark Organic Silicon real-time releases metal silicon inventory and prices; Midstream Maihao New Materials dynamically adjusts the 107 glue production schedule based on downstream orders; Downstream Silicon Treasure Technology connects with photovoltaic enterprises' needs through the platform and customizes and develops packaging adhesives with a 30% improvement in weather resistance.


In the past, the lag in upstream and downstream information led to inventory backlog. Now, through the industrial brain, our equipment utilization rate has increased from 78% to 92%, "said the production director of Maihao New Materials. Data shows that from January to September 2025, the average inventory turnover days of Yongxiu Organic Silicon Enterprises will be shortened from 45 days to 28 days, and operating costs will be reduced by 15%.


High end applications: from building sealing to medical implantation
Technological breakthroughs drive the penetration of products into high value-added fields. The electric liquid silicone rubber developed by Runhe Materials has been applied to ultra-high voltage transmission lines, with a temperature resistance level of 300 ℃; The polydimethylsiloxane vitreous body jointly developed by Jiangxi Huaer Runzhi and Wuhan University has successfully entered the clinical stage of ophthalmic implant devices.


The market size of medical grade silicone rubber is expected to exceed 8 billion yuan by 2025, with a compound annual growth rate of 25%, "said Liao Jun, Vice Chairman of the China Fluorosilicone Organic Materials Industry Association. Within the Yongxiu industrial cluster, 12 enterprises have obtained ISO 13485 medical system certification, with products covering sub sectors such as insulin pumps and artificial joints.
