Entering the fourth quarter of 2026, structural games in China’s domestic silica market have become more prominent. Instead of overall synchronized rises or falls, the market shows completely divergent performances between general‑purpose grades and speciality products. Affected by neutral operating rates of downstream traditional rubber goods, inventories of ordinary precipitated silica have built up. Trading turnover has slowed down. Most manufacturers deliver goods following market fluctuations with limited price swings. Small‑and‑medium‑sized enterprises face mounting survival pressure as profits are squeezed jointly by raw‑material costs and low‑price competition. By contrast, tire‑grade highly‑dispersed silica, hydrophobic fumed silica and various surface‑modified speciality powders see extended order‑delivery cycles. Many producers operate under order‑backlog conditions. High‑end products hold firm pricing power and serve as the major profit source for the industry. With normalized enforcement of environmental‑protection and energy‑consumption regulations, backward and inefficient capacities keep phasing out. Industrial resources keep concentrating on leading enterprises equipped with complete modification processes and robust R&D capabilities. Competition has shifted from sheer production‑capacity scale toward powder‑modification technologies, batch‑to‑batch stability and supporting technical services.

　　The tire sector remains silica’s largest consumption segment. Sustained high carbon‑black prices improve the cost‑effectiveness of silica substitution. Major domestic tire enterprises keep adjusting formula systems and steadily raise silica filling ratios. Stringent requirements of new‑energy‑vehicle tires for low rolling resistance, strong wet‑grip performance, wear resistance and noise reduction force tire manufacturers to adopt higher loading of highly‑dispersed silica. Meanwhile, overseas carbon‑related trade barriers keep being implemented. Export‑oriented tires must satisfy strict carbon‑footprint accounting requirements, further pushing tire producers targeting overseas markets to iterate filler formulas. Nevertheless, tire‑formula certification involves complicated procedures and lengthy verification cycles. Demand grows step‑by‑step. Large‑scale substitution dividends are expected to materialize gradually over the next two years rather than breaking out in the short term.

　　Beyond tire‑rubber applications, silica’s application boundaries keep expanding. Demand shares from new‑energy, electronic‑material and fine‑chemical sectors keep rising, offsetting demand volatility in traditional fields. Within the silicone industrial chain, hydrophobic fumed silica acts as reinforcing, thixotropy‑enhancing and anti‑settling agent for silicone rubber, photovoltaic sealants and electronic potting compounds. Demand for such fillers grows steadily alongside capacity expansion of domestic high‑end silicone production. In coatings and inks, modified silica delivers matting, anti‑sedimentation and scratch‑resistant effects, with rising consumption in water‑borne paints, industrial wood coatings and special‑purpose printing inks. High‑purity, ultra‑fine and custom‑modified silica sees rapid demand growth in high‑end scenarios such as lithium‑battery separator coatings, photovoltaic adhesive films, semiconductor polishing auxiliaries, cosmetic powder carriers and dental‑resin fillers, accelerating domestic substitution of imported speciality grades. As anti‑caking carriers in agrochemical and feed industries, silica maintains steady rigid demand and further consolidates overall downstream consumption.

　　On the foreign‑trade front, China’s silica exports remain robust in Q4. Rubber‑ and‑coating industries in Southeast Asia, South Asia, Latin‑America and other regions keep expanding. Local supply of high‑end powders falls short, leading to sustained imports of precipitated and fumed silica from China. Overseas procurement standards keep tightening. Carbon‑footprint reports, low‑carbon production qualifications and stable batch quality are gradually turning into hard purchasing thresholds. Domestic leading enterprises with sound quality‑control systems are more accessible to high‑end overseas orders. Domestic import volumes keep shrinking. Only a tiny number of ultra‑demanding speciality silica grades still rely on foreign supplies, and domestic‑substitution progress continues advancing. Defects persist in export mix: large‑volume shipments are still dominated by ordinary general‑purpose grades. Exports of high‑value‑added custom‑modified products account for a relatively low proportion, leaving plenty of room for domestic enterprises to compete in global high‑end markets.

　　Industrial reshaping continues on the supply side. Constraints on energy consumption as well as waste‑water and exhaust‑gas emissions have tightened. Many small‑and‑medium‑sized production units featuring outdated facilities and no supporting modification capacity face restricted operating rates, lifting market concentration further. Supported by integrated raw‑material layouts and continuous‑modification production lines, leading enterprises can steadily deliver high‑end powders with consistent performance, gaining access to core supply chains of top domestic and overseas new‑material and tire clients and building technical and customer barriers. Many market leaders refrain from blind expansion of ordinary precipitated‑silica capacities. Instead, they invest in speciality‑silica projects and develop new products targeting hydrophobicity, high transparency, low conductivity, ultra‑fine particle sizes and other directions to evade low‑end price wars.

　　From the cost perspective, prices of soda ash, quartz sand, coal and electricity stay firm in Q4, creating substantial cost pressure for small‑and‑medium‑sized producers. Concentrated equipment maintenance tightens spot‑market supply of soda ash, the core feedstock for precipitated silica, lifting production costs of general‑purpose grades and further compressing thin profit margins of low‑end products. Shrinking availability of high‑purity quartz sand pushes up feedstock costs for fumed silica and reinforces resource‑and‑technology barriers in high‑end segments. Through long‑term price‑locked contracts, waste‑heat recovery, water recycling and other cost‑reduction measures, large‑scale enterprises hedge raw‑material‑price fluctuations and achieve far better profitability than smaller peers, reinforcing industry polarization.

　　In terms of R&D, surface‑modification technology serves as the core differentiator among manufacturers. Traditional wet‑modification processes keep getting optimized with improved powder dispersibility, activation rate and weather resistance. Industrial‑scale application of innovative in‑situ and continuous‑modification technologies alleviates long‑standing industry bottlenecks including powder agglomeration, poor matrix compatibility and out‑of‑control system viscosity. New tailor‑made modified‑silica products for UV resins, polyurethane, battery coatings and high‑end silicone rubber keep emerging. Customization and functionalization become mainstream R&D orientations. In future, enterprises capable of powder‑structure regulation, precise functional‑group modification and simultaneous provision of formula‑technical support will continuously capture premium benefits from high‑end markets.

　　According to Q4 analyses from industrial institutions, China’s silica market will sustain its structural pattern in the short run: general‑purpose grades fluctuate weakly while high‑end modified products hold firm market performance. Burdened by high inventories and sluggish downstream demand, ordinary precipitated silica lacks upward price momentum. Highly‑dispersed tire‑specific silica, fumed silica and high‑purity ultra‑fine speciality powders maintain strong market sentiment driven by rigid downstream demand and tight supply. In the medium‑to‑long term, three major logics remain valid: low‑carbon transformation of transportation, domestic substitution of new materials and expansion of new‑energy industries. The general trend toward functionalized, customized and high‑end silica is irreversible. Industrial competition no longer centers on capacity scale. Comprehensive competitiveness is determined by technology, product quality, supporting services, low‑carbon manufacturing and compliance certifications. Market increments and profits will further gravitate toward leading enterprises, and industrial‑upgrading momentum will keep accelerating.
