In late August, China’s precipitated silica market continues to operate with prominent structural divergence. Supply of conventional general‑grade precipitated silica remains sufficient with prices fluctuating within a narrow range. By contrast, high‑dispersion tire‑grade, hydrophobically‑modified and fumed silica maintain strong market resilience. Downstream operating rates vary across end‑use sectors. Export business is affected by overseas regulations and regional demand shifts. The industry has moved past the era of universal price rises or declines. Product differentiation has become the core factor determining manufacturers’ profit performance.
In terms of market prices, current mainstream quotations for domestic rubber‑grade general precipitated silica stand at 6500‑7500 RMB per ton. Overall market supply is abundant. Small‑and‑medium‑sized producers face heavy inventory pressure. Some manufacturers offer discounts to secure orders, squeezing overall profit margins. For high‑end grades, high‑dispersion silica for green tires and surface‑modified special silica enjoy steady order backlogs and stronger bargaining power compared with commodity grades. The fumed silica market also presents clear segmentation. Mid‑to‑low‑end domestic fumed silica is priced at 20.5‑24 RMB/kg, high‑end domestic grades stay at 26‑32.5 RMB/kg, while imported premium fumed silica holds at 29‑39 RMB/kg, supported by rigid demand from high‑end electronics and silicone rubber sectors.
On the supply side, China possesses huge total capacity for precipitated silica. After years of capacity expansion, general‑grade capacity is close to saturation. Constrained by environmental protection and energy‑consumption policies, backward small‑scale production capacity keeps phasing out, and market resources are further concentrating among leading enterprises. Leveraging integrated raw‑material supply and advanced process technology, major players keep expanding capacity for high‑dispersion and modified functional silica to capture markets for new‑energy tires and premium silicone rubber. Many small‑and‑medium plants suffer volatile operating rates due to higher raw‑material, environmental‑protection and operation costs. They mainly produce low‑value commodity products, intensifying homogeneous market competition. Meanwhile, domestic substitution for fumed silica keeps advancing, yet ultra‑high‑purity low‑metal‑ion special grades still rely on imports, representing a key technical focus for local manufacturers.
For raw‑material costs, sodium silicate and sulfuric acid, core feedstocks for precipitated silica, show limited price swings recently without sharp cost surges or drops. Cost pressure mainly comes from energy consumption, waste‑gas‑wastewater treatment and purchase of modification additives. During summer production, industrial water and power consumption stay at high levels. Rigidly rising costs for environmental governance and three‑waste treatment further erode profit margins of commodity‑grade products, forcing producers to shift toward high‑value modified grades. The volume‑oriented business model becomes increasingly unsustainable.
Downstream demand differences further amplify market divergence. The tire industry remains the largest consumer of silica. Rising penetration of new‑energy vehicles drives higher consumption of high‑dispersion silica for low‑rolling‑resistance green tires. Major tire manufacturers maintain relatively stable operation and robust purchasing for premium grades. Many small tire factories run at low load rates amid weak end‑market consumption and push for lower prices on general‑grade materials. In silicone rubber and sealant sectors, producers of neutral silicone sealants and special fluoro‑silicone rubber keep steady demand for hydrophobic modified silica, prioritizing dispersion and reinforcing performance over price. Besides, non‑rubber sectors including coatings, toothpaste and pesticide carriers generate steady consumption. Emerging fields such as lithium‑ion‑battery diaphragm coating, photovoltaic sealing materials and electronic packaging fillers unlock new growth opportunities for specialty silica, setting stricter requirements for purity, particle size and surface‑treatment technology. Traditional segments such as shoe soles and ordinary rubber miscellaneous goods enter seasonal off‑peak periods, with purchasing activities slowing and hand‑to‑mouth buying prevailing.
In foreign trade, China’s total silica exports remain at a high level. Southeast Asia, the Middle East and South America serve as major export destinations, where local tire and rubber‑plastic industrial transfer fuels steady regional demand growth. Nevertheless, overseas trade barriers keep tightening. EU CBAM and REACH regulations impose new requirements on carbon footprint and impurity indicators for exported goods. Export obstacles increase for low‑end commodity silica. High‑end modified products with low‑carbon production processes and complete test reports gain stronger overseas competitiveness. Many local suppliers adjust export mix, cutting shipments of low‑margin commodity products and stepping up overseas promotion of high‑value functional silica.
Market outlook: In the short run, hampered by seasonal off‑peak consumption, conventional precipitated silica has limited upward potential and will likely stay weak‑and‑stable, with prices determined by supply‑demand balance and cost bottom lines. High‑dispersion, hydrophobic‑modified and fumed silica will hold firm, backed by demand from emerging downstream industries. In the medium‑to‑long term, industry logic has fully shifted toward product differentiation. The era of blind capacity expansion is over. Enterprises capable of customized surface modification, stable index control and tailored solutions for new‑energy and electronic‑material markets will capture incremental dividends. Homogeneous backward capacity will keep exiting, and structural divergence within the sector will further deepen.
