Entering mid-August, China’s silica market continues its operation amid the traditional summer off-season, featuring a clear divergent trend: conventional precipitated silica prices see mild steady adjustments, high-end fumed silica maintains firm prices amid tight supply, while costs from upstream raw materials and downstream demand interact and counterbalance each other. Affected by recent raw material fluctuations, enterprise operating rates, end-user purchasing intentions and market feedback from emerging application sectors, the industry’s performance gap has widened distinctly. Demand from the traditional rubber sector is sluggish, yet orders from high-value-added fields including organosilicon, new energy lithium batteries, photovoltaic adhesives, daily chemicals and pharmaceuticals keep growing steadily, preventing overall sharp declines across the market.
From the upstream cost perspective, sodium silicate and sulfuric acid, the two core raw materials for silica, show stark regional price gaps, delivering varying cost support for finished silica products. As the primary feedstock for precipitated silica, sodium silicate is adequately supplied nationwide. Only small-scale workshops in East and North China temporarily cut production due to periodic environmental inspections, which exerts no impact on supply from major mainstream manufacturers. Driven by mild hikes in soda ash and quartz sand, prices of sodium silicate edge up by 1% to 2%, moderately lifting the cost floor of precipitated silica. The sulfuric acid market presents greater regional disparity: chemical hubs in East and South China hold ample inventory with mounting sales pressure, leading to a 2%-3% month-on-month price drop; North and Northwest China witness slight price increases of 1%-2% due to higher long-distance logistics expenses and steady rigid industrial demand. Such north-south cost gaps further widen the negotiation range of silica prices in different regions. Overall, upstream raw materials fail to fuel a strong price surge, offering only mild cost support that cannot trigger widespread price hikes for precipitated silica.
In terms of supply, the national operating rate of the domestic silica industry stays stable between 75% and 80%. Leading large-scale producers operate at nearly full capacity to fulfill long-term contracts signed previously, keeping inventory at a reasonable low level. Small and medium manufacturers flexibly adjust production schedules according to needs to avoid inventory backlogs, constrained by environmental regulations, routine equipment maintenance and slim profit margins. New production capacity expansion proceeds slowly; only a small precipitated silica project with an annual output of 10,000 to 20,000 tons is planned for commissioning recently, with an unclear launch timeline, which will not alter the domestic supply-demand landscape in the short term. By product type, conventional industrial-grade precipitated silica is abundant with flexible purchasing terms; high-specific-surface-area, high-dispersity tire-grade precipitated silica and domestic premium fumed silica are relatively scarce, prompting some producers to extend delivery cycles. Imported high-end fumed silica arrives slowly due to overseas capacity allocation and prolonged sea transportation, sustaining its shortage in the domestic market. As of August 12, the latest market quotations are as follows: mainstream tax-inclusive prices for rubber-grade precipitated silica range from 6,500 to 7,500 RMB per ton, with notable gaps based on regions and specific surface area specifications; mid-to-low-end domestic fumed silica is priced at 20 to 23.5 RMB per kilogram; premium fumed silica dedicated to photovoltaic and organosilicon applications costs 25 to 28 RMB per kilogram; imported high-purity fumed silica falls within 28 to 38.5 RMB per kilogram, forming a clear price tier system.
Downstream demand serves as the core driver behind the market divergence. The tire and rubber industry, the largest traditional consumption sector, is in its summer off-season. Sluggish vehicle production and sales lead to gradual inventory accumulation of finished tires and slight cuts in tire factory operating rates. Manufacturers adopt a cautious purchasing strategy of restocking only to meet immediate needs, with little willingness for bulk stockpiling, dampening trading activity for ordinary precipitated silica. Nevertheless, the popularization of green tires advances steadily, and the gradual replacement of carbon black by high-dispersity silica delivers long-term support for premium precipitated silica products.
In sharp contrast, demand from organosilicon supporting industries, new energy, photovoltaic, daily chemicals, pharmaceuticals, coatings and adhesives keeps rising robustly. The booming production of addition-cure silicone rubber, liquid silicone rubber and silicone gel generates consistent rigid demand for fumed silica as a key reinforcing and thickening filler, which constitutes the primary consumption pillar for fumed silica at present. Thriving production of photovoltaic sealing adhesives and thermal conductive potting compounds greatly boosts consumption of ultrafine fumed silica. Demand growth in lithium battery separator coating stands out, surging over 43% year-on-year and emerging as a brand-new growth driver for high-end silica. Besides, steady rigid demand from food anti-caking agents, feed additives, inks and coatings offsets the demand slump brought by the tire off-season effectively.
Industry institutions predict that the divergent market pattern will persist through mid-to-late August. Dragged down by the sluggish tire sector, conventional precipitated silica prices are likely to inch down slightly with flexible negotiation margins. Supported by sustained rigid demand from organosilicon, new energy and photovoltaic industries coupled with tight spot supply, premium fumed silica prices will remain solid. As the traditional peak season for the tire industry kicks off in September, rebounding stocking activities from vehicle factories and recovery in the construction and coating sectors are expected to lift overall silica demand and drive prices upward.
