Mid-August sees China’s chemical sector still stuck in the traditional summer off-season. Downstream buyers including rubber product manufacturers, general coating factories and ordinary rubber-plastic component producers slow down procurement, with most terminal enterprises adopting on-demand restocking and strict inventory control. In stark contrast to the annual industry-wide price cuts and inventory liquidation every sweltering summer, the dividing line between peak and off seasons for silica has blurred further in 2026, with drastic cyclical price swings largely fading away and the tiered market pattern becoming entrenched. Conventional precipitated silica for tires maintains balanced supply and demand with mild price volatility. High-end fumed silica for photovoltaic encapsulation, lithium battery diaphragm coatings and precision electronic sealing suffers persistent spot shortages with firm and rising quotations. Low-carbon silica recycled from rice husk ash solid waste keeps securing long-term European and American orders thanks to its favorable carbon footprint, steadily optimizing the structure of foreign trade. Industrial competition has fully shifted to comprehensive strength contests covering low-carbon qualifications, customized modification technologies and multi-scenario adaptation capabilities.
Per the latest industrial monitoring data dated August 15, the benchmark ex-factory price of domestic industrial-grade precipitated silica holds steady at 6,000 CNY per ton, edging up 1.12% since early August with gentle movements over the past two weeks without sharp fluctuations. Clear price gaps exist across segmented grades: regular rubber-reinforcing silica ranges from 5,800 to 6,200 CNY per ton; high-dispersion modified silica exclusively for new energy vehicle tires has climbed to 6,300–6,700 CNY per ton; food and pharmaceutical high-purity precipitated silica stabilizes at roughly 6,500 CNY per ton. Price stratification is even more pronounced for fumed silica: mid-to-low-end domestic general types cost 20–23.5 CNY per kilogram; hydrophobic modified high-end fumed silica for photovoltaics and lithium batteries is priced at 25–28 CNY per kilogram; imported ultra-high-purity electronic-grade varieties remain within 28.8–39 CNY per kilogram, alongside steady progress in domestic substitution of premium products.
Supply side features stark operating rate divergence, with the overall industrial operating rate staying between 76% and 81%. Leading silicon material enterprises run production lines at full capacity around the clock, backed by long-term framework orders for new energy adhesives, eco-friendly tires and daily chemical raw materials, while keeping inventories consistently low. A vast number of small and medium manufacturers curtail production voluntarily and schedule selective equipment maintenance, hampered by insufficient sporadic orders and slim processing profits. They avoid loss-making price-driven bulk sales amid off-season cutthroat competition, effectively easing the oversupply of low-end products. Sustained high temperatures widen the production cost gap between northern and southern regions. Established industrial clusters in East and South China operate cooling systems nonstop, coupled with surging energy consumption for harmless wastewater and waste gas treatment plus routine operation costs of online environmental monitoring equipment, pushing up rigid comprehensive production costs and leaving little room for price declines of low-end products. Northern production bases enjoy favorable summer temperatures, spacious factory premises and shortened logistics via nearby raw material procurement, cutting energy costs for cooling and three-waste disposal and retaining prominent cost advantages. Recently, numerous inland traders have shifted purchasing focus northward, quietly reshaping the regional circulation pattern of silica supplies. Industrial surveys confirm that structural overcapacity still plagues conventional mineral-based silica. Demand growth for tires matched to fuel vehicles remains sluggish, with only the steady tire replacement market propping up the sector and unable to drive an upturn for low-end grades. Though homogeneous price competition has cooled markedly, it has not vanished entirely.
Booming emerging non-tire sectors have overtaken traditional rubber applications to become the core engine driving industrial growth. A cluster of photovoltaic power stations are scheduled for delivery in the third quarter, including residential distributed photovoltaic systems and large-scale ground-mounted energy storage projects under mass completion and commissioning, fueling thriving production and sales of silicone sealants for photovoltaic module encapsulation. Hydrophobic nano fumed silica acts as a vital anti-settling, thickening and anti-aging filler in adhesive formulations. Downstream adhesive producers have locked in full-quarter purchasing volumes in advance, leading to scarce spot supplies and extended mainstream delivery cycles of two to three months. Power and energy storage battery manufacturers continuously upgrade ceramic protective coating technologies for separators. High-purity ultrafine silica greatly enhances separators’ heat resistance and puncture resistance, resulting in year-on-year consumption growth. Production schedules of major domestic material suppliers have been postponed to early October amid mounting order delivery pressure. Rising penetration of new energy vehicles brings heavier curb weight and stronger instantaneous torque, requiring a 15%–20% higher silica dosage for quiet, low rolling resistance tire formulas compared with fuel vehicle tires. This fuels steady demand growth for high-dispersion modified precipitated silica, one of the few stable bright spots within the tire segment. Furthermore, demand for refined niche fields remains immune to seasonal swings: abrasives for oral care, soothing additives for personal care and anti-caking excipients for pharmaceutical tablets register stable orders year-round. Ultra-high-purity fumed silica serves as the foundational material for sealing, shock absorption and thermal buffering components in wireless earbuds, smart bracelets and miniature sensors. The growth rate of these premium niche markets far outpaces traditional industrial sectors, continuously broadening silica’s application scope.
China’s silica foreign trade maintains robust growth in both volume and value with increasingly diversified export destinations, cushioning market fluctuations triggered by the EU Carbon Border Adjustment Mechanism (CBAM). Customs statistics for the first half of the year show China exported 769,000 tons of silica from January to June, a year-on-year rise of 11.90%, with total export volume hitting USD 442 million, surging by 21.15% and pushing average export prices upward simultaneously. Imports totaled merely 40,000 tons, dropping 8.95% year-on-year amid accelerated domestic substitution of high-end products. Following the regular enforcement of the EU CBAM, conventional silica manufactured via quartz sand and sulfuric acid processes carries a large carbon footprint, triggering sharp hikes in tariff expenses. Small and medium factories incapable of low-carbon renovation and complete carbon emission ledger documentation have gradually withdrawn from the European market. In contrast, domestic leading firms’ years of research on rice husk ash recycling production technologies are now reaping rewards. Replacing mineral raw materials with agricultural waste rice husks slashes carbon emissions per ton of finished goods by over 60% versus traditional methods, with certain products achieving carbon negativity. Having obtained EU green raw material certifications, these varieties not only evade steep carbon tariffs overseas but also command an 8%–15% green premium, with order growth vastly outperforming standard industrial grades.
Currently, Southeast Asia, the Middle East, Central Asia and North Africa have evolved into core overseas destinations for China’s mid-to-low-end silica. Benefiting from zero-tariff policies under the RCEP, Vietnam, Indonesia, Thailand and other Southeast Asian nations expand production capacity for rubber goods, construction sealants and daily chemicals rapidly, absorbing massive volumes of conventional precipitated silica. Extensive urban infrastructure and oil & gas supporting projects across the Middle East spur explosive demand for construction sealing materials and industrial rubber parts, pushing H1 import volumes up over 30% year-on-year. Steady development of light industries in Central Asia releases mild demand for basic silica fillers. Multiple industrial giants have rolled out global capacity layouts, building fine processing and packaging bases in Southeast Asia. Domestic factories undertake core procedures including purification and surface modification, while overseas facilities conduct packaging and delivery to comply with local trade rules, circumvent carbon tariffs and trade barriers and consolidate international market share.
Low-carbon circular production and customized formula R&D have turned into the watershed reshuffling the industry, accelerating the phase-out of high-energy-consuming, inefficient backward capacity. The conventional process featuring high-temperature melting for water glass preparation followed by sulfuric acid acidification consumes large quantities of non-renewable quartz ore, generates over 4 tons of carbon emissions per ton of product alongside massive high-salinity wastewater discharge, driving annual rises in environmental maintenance costs and shrinking profit margins. The large-scale commercialization of innovative technologies such as rice husk ash resource utilization and carbon dioxide carbonization has reversed this trend. Silicon is extracted from recycled rice husk ash, waste heat from incineration is recovered for production heating, carbon dioxide replaces sulfuric acid in the acidification stage, and byproducts are recycled repeatedly, fundamentally resolving the challenge of high-salinity wastewater treatment. This model not only consumes agricultural solid waste and eliminates air pollution from open-air rice husk burning but also drastically cuts energy consumption and carbon emissions, yielding products with superior purity and dispersibility that satisfy stringent standards for premium daily chemicals and eco-friendly tires. Many leading enterprises have launched blockchain-enabled full-chain carbon tracing systems, which record complete carbon emission data covering raw material procurement, production processing and finished product delivery, securing International Environmental Product Declarations (EPDs) and granting them prominent advantages in overseas brand supply chain admission and project bidding. On the contrary, constrained capital prevents small workshops from upgrading environmental equipment and establishing carbon accounting systems, and they lack surface modification R&D capabilities. Competing only for scattered small orders via low prices, their survival space keeps shrinking, leading to accelerated capacity concentration among top enterprises. Industry institutions forecast the combined market share of the top five firms will rise markedly by the end of 2026.
Industrial analysts project a sustained divergent market trend from late August through the fourth quarter. The late August period will remain entrenched in the summer off-season without dramatic price swings: conventional precipitated silica will consolidate within a narrow fluctuation band, while tight supply will persist for high-end fumed silica dedicated to photovoltaics, lithium batteries and electronics with prices staying firm. Entering September, rubber processing, waterproof material and industrial coating industries will kick off the traditional autumn production peak, coupled with concentrated downstream stocking ahead of the Mid-Autumn Festival and National Day holidays, ushering in a mild phased rebound across the overall silica market. In the long run, the extensive development model reliant on blind capacity expansion and vicious price wars has come to an end. Customized surface modification technologies, closed-loop low-carbon circular production and balanced domestic and overseas market deployment will define enterprises’ core competitiveness. Silica will thoroughly break free from its single identity as a rubber reinforcing filler and evolve into a vital inorganic silicon new material widely applied across six major sectors: new energy storage, automobile manufacturing, fine daily chemicals, biomedicine, precision electronics and agricultural & forestry circular materials, advancing continuously toward greener, finer and high-end development.
