By the end of August, China's silicone industry, driven by the dual goals of "dual carbon" and the demands of emerging industries, is undergoing a crucial transformation from scale expansion to in-depth technological development. The industry is characterized by three major features: stratified demand, accelerated technological iteration, and deepened integration of the industrial chain. High-end products and green manufacturing have become the core growth poles.
Demand side: Traditional markets remain stable, while emerging fields are experiencing explosive growth
The traditional demand for building sealing materials, electronic and electrical insulation materials, etc. maintained a steady growth, but the growth rate slowed down. The new energy sector has become the main driving force: The encapsulation adhesive for photovoltaic modules needs to meet the weather resistance requirements of double-glass modules and support the 25-year lifespan of power stations. New energy vehicle battery sealants have set higher standards for flame retardancy and thermal conductivity, promoting the improvement of lithium battery energy density through surface modification of silicon-carbon anode materials. The demand in the medical and health sector has significantly upgraded. The proportion of high-end products such as biocompatible silicone catheters and implantable device coatings has increased. Some enterprises have already broken through the technical barriers of degradable silicone.
On the supply side: Technological breakthroughs reshape the competitive landscape
Leading enterprises consolidate their advantages through a full-chain layout covering "industrial silicon - monomer - deep processing". For instance, the Xinjiang coal-electricity-silicon integrated base has reduced the cost of industrial silicon, and the chloromethane recycling process has achieved near-zero emissions of by-products. Breakthroughs have been made in the research and development of functional materials: phenyl silicone resin enhances the high-temperature resistance of semiconductor packaging adhesives, self-healing silicone rubber extends the sealing life of photovoltaic modules, and polysiloxane-based solid electrolytes optimize the safety performance of lithium batteries. The effect of technology premium has emerged. The gross profit margin of enterprises that master core processes is 5 to 8 percentage points higher than the industry average.
Future Outlook: Driven by both high-end and green development
It is expected that by 2030, the demand share in the new energy sector will exceed 35%, becoming the core engine of industry growth. Enterprises need to focus on three major directions: First, break through the bottleneck of domestic production of electronic-grade materials and narrow the gap with foreign-funded enterprises; Second, deepen the application of AI-driven molecular design platforms to shorten the development cycle of new materials; Third, a carbon footprint tracking system should be established to meet international green trade rules such as the EU's CBAM. With the promotion of the collaborative innovation model among industry, academia, research and medical institutions, the industrialization process of special silicone materials will be further accelerated.
