(July 29, 2026)The penetration rate of new energy vehicles keeps rising, ushering in a new round of demand expansion cycle for high-dispersion silica dedicated to tires. Countries worldwide keep tightening standards for tire energy efficiency and carbon emission control. Coupled with the popularization of new energy passenger vehicles and lightweight commercial vehicles, low rolling resistance green tires have become the mainstream development direction of the industry. As the core reinforcing filler to break the tire "performance triangle", high-dispersion precipitated silica sees steadily growing market demand. The focus of industrial capacity competition is shifting rapidly from general-grade products to tire-specific grades featuring excellent dispersibility and low-carbon properties, and the supply-demand pattern continues to improve.
For a long time, carbon black has been widely used as reinforcing filler in formulations of traditional fuel vehicle tires. New energy vehicles carry greater weight and deliver higher instantaneous torque, imposing stricter requirements on tire wear resistance, wet grip and rolling resistance control. Conventional silica suffers limited dispersibility and tends to agglomerate during mixing, making it difficult to balance tire energy consumption, safety and service life simultaneously. High-dispersion silica with pore structure and particle size distribution regulated via special processes, when used together with silane coupling agents, can effectively reduce tire rolling resistance and power consumption during driving, while improving anti-slip performance on wet roads, matching the energy-saving demands of new energy vehicles. With the steady growth of domestic tire exports, the continuous implementation of EU tire labeling regulations and carbon border mechanisms raises overseas buyers’ requirements on tire filler quality and carbon footprint certifications. This forces domestic tire manufacturers to optimize tread formulations and increase the dosage of high-dispersion silica.
In the second half of 2026, leading domestic tire enterprises keep expanding production capacity for new energy vehicle tires, and multiple high-performance tread production lines are successively put into operation, pushing up procurement demand for high-end silica. Many leading silica enterprises adjust production plans, slow down capacity expansion of general industrial grades, and concentrate resources on upgrading production lines for tire-specific high-dispersion products. They continuously optimize synthesis processes and strictly control structural indicators of products. Some enterprises simultaneously carry out low-carbon process transformation, conduct product carbon footprint accounting and third-party certification, and develop a series of low-carbon high-dispersion products tailored for overseas export orders. Meanwhile, many tire manufacturers establish long-term joint R&D mechanisms with silica raw material suppliers to continuously optimize filler matching solutions for new energy tire formulations.
Tires for different vehicle models generate differentiated product demands. Tires for household new energy passenger vehicles prioritize low rolling resistance and low noise, favoring medium-to-high specific surface area high-dispersion silica; tires for heavy-duty electric commercial vehicles place higher emphasis on wear resistance and tear strength, raising standards for powder reinforcing capacity; high-end sports tires need to balance grip and durability. A single specification cannot cover all application scenarios, driving silica enterprises to build multi-gradient tire-specific product portfolios and meet formulation demands of various tire manufacturers through customized processes. Procurement thresholds for downstream tire enterprises keep rising. Apart from basic physical and chemical indicators, tests on mixing process performance and long-term aging stability are added, extending the qualification verification cycle for suppliers.
Broad market potential comes alongside prominent industrial challenges. The production of high-end high-dispersion silica demands strict control over temperature and reaction rate during manufacturing, bringing great difficulties to process debugging. Global material giants have occupied the high-end tire market for years with complete formulation databases. Restricted by technologies, small and medium-sized domestic manufacturers can only produce silica with unstable dispersibility and compete in low-end markets. In addition, cyclical price fluctuations of supporting raw materials such as silane coupling agents continuously squeeze profit margins of the rubber filler industrial chain.
Market differentiation becomes increasingly obvious. Leading powder enterprises equipped with stable processes, comprehensive application R&D capabilities and accessible carbon footprint compliance documents achieve sustained order growth. Manufacturers lacking technical reserves that can only mass-produce general silica face mounting competitive pressure. The downstream tire industry moves toward concentration, and increasing orders flow to raw material suppliers with comprehensive service capabilities.
Industrial research institutes predict that output and sales volume of new energy vehicles will maintain growth in the next three years, the penetration rate of green tires will rise steadily, and the market scale of tire-specific high-dispersion silica will keep expanding. As the largest downstream application market for silica, this track delivers sound profit margins for high-end products and serves as a core layout sector for domestic silica manufacturers.
In the long run, deep cultivation of high-dispersion silica for tires helps enterprises consolidate fundamental business and expand market share by capturing development dividends brought by new energy vehicles. Domestic silica manufacturers should continuously optimize synthesis technologies, improve powder dispersibility, and build full-process low-carbon production systems together with international compliance certifications. Enterprises need to strengthen collaborative R&D with tire producers, continuously upgrade special products adapted to new energy tires, steadily advance import substitution of high-end tire fillers, and boost the overall competitiveness of China’s silica industry in the global rubber raw material market.
