(May 27, 2026) Currently, the domestic white carbon black industry faces structural contradictions of overcapacity at the low-end end and insufficient supply at the high-end end. The supply-demand mismatch between general-purpose products and high-end specialty materials is becoming increasingly prominent, becoming the main bottleneck restricting the industry's high-quality development. Driven by downstream industrial upgrading and overseas market demand, how to resolve structural capacity issues and optimize supply structure has become the core issue of the silica industry at this stage.
In terms of overall production capacity, China is a major producer of silica worldwide, with precipitation-based silica capacity ranking among the top in the world, and a large amount of capacity concentrated in the general rubber reinforcement sector. Due to the initial capacity expansion, the output of silica for ordinary tires is sufficient, resulting in an oversupply market. Companies rely on low prices to capture market share, continuously squeezing industry profits, and many small and medium-sized manufacturers are stuck in the dilemma of increasing production without increasing revenue.
In stark contrast, there is a severe shortage of products in the high-end segment. Products such as vapor-phase silica, highly dispersed specialized silica, daily chemical grade, electronic grade, and photovoltaic adhesive-specific silica have relatively few domestic companies capable of stable mass production due to complex production processes, high technical thresholds, and strict quality control, and some high-end products still rely on imports. Downstream industries such as new energy, high-end beauty, precision electronics, and high-end sealing materials are developing rapidly, further widening the market gap in high-end silica, and the supply-demand mismatch continues to worsen.
The demand divergence continues to intensify this contradiction. Traditional tire and rubber industries have stable but sluggish growth, saturating demand for ordinary silica; Meanwhile, emerging sectors such as new energy support, new materials, and high-end daily chemicals continue to see rising demand for customized silica that is highly purified, low in impurity, and stable in performance. Traditional capacity cannot adapt to emerging market standards, resulting in idle low-end capacity and shortages in high-end markets, resulting in low resource utilization efficiency.
The export market also reflects structural issues. General-purpose silica is exported at low prices, relying on price advantages to capture the market, resulting in thin profit margins; High-end modified silica black, due to its scarcity, has strong bargaining power and stable orders in overseas markets, but domestic production capacity is limited, making it difficult to meet large-scale overseas procurement demand.
Industry experts say that resolving the supply-demand mismatch cannot simply reduce capacity, but rather involves eliminating low-end products, upgrading mid-end, and expanding high-end products. On one hand, accelerate the elimination of outdated capacity that does not meet environmental standards, has high energy consumption, and low added value; On the other hand, it promotes technological upgrades in existing enterprises and lays out the R&D of high-end functional products; At the same time, guide the industry to rationally expand production and avoid homogeneous redundant construction.
In the future, as the supply structure continues to optimize, the white carbon black industry will gradually overcome the low-end internal competition bottleneck, achieving a healthy pattern where general products guarantee basic demand and high-end products capture incremental markets, truly transforming from a large capacity country to a quality-strong one, providing stable and reliable raw material support for China's new materials industry and high-end manufacturing sectors.
