(May 10, 2026) Today, Shandong Silicon New Materials Co., Ltd. (hereinafter referred to as "Shandong Silicon"), a leading enterprise in the domestic silica industry, officially announced that its annual output of 100,000 tons of high-end special silica production line has been successfully put into operation.
According to the relevant person in charge of Shandong Silicon Technology, the high-end special silica production line put into operation this time, with a total investment of 320 million yuan, adopts a self-developed green and clean production process, which can produce high-end products such as high-dispersion silica and fumed silica, which are mainly used in new energy vehicle tires, high-end coatings, electronic sealing materials and other fields. After the production line is put into operation, the company's high-end silica production capacity will increase to 250,000 tons/year, accounting for more than 60% of the company's total production capacity, and the products will be supplied to domestic leading rubber and plastic enterprises and overseas markets at the same time, and the annual new output value is expected to exceed 800 million yuan.
The reporter learned that not only Shandong Silicon, but also a number of domestic silica companies have recently increased their layout in high-end fields. At the beginning of this month, Zhejiang Hengyi Chemical announced the launch of a photovoltaic silica project with an annual output of 80,000 tons, focusing on the demand in the field of photovoltaic module packaging; Jiangsu Kaisheng New Materials cooperates with universities to develop high-purity silica for use in the field of biomedicine, further expanding the boundaries of product applications. Behind the intensive layout of enterprises is the continuous expansion of downstream application scenarios of silica and the rapid growth of high-end demand.
From the perspective of the application market, the demand for high-end silica shows a multi-point flowering trend. In the field of new energy vehicles, as the production and sales of domestic new energy vehicles continue to rise, the average annual growth rate of demand for high-dispersion silica, as the core raw material of green tires, remains above 20%. In the photovoltaic field, silica has become a key auxiliary material for photovoltaic module packaging with its excellent weather resistance and sealing, and the market demand continues to increase. In the field of high-end daily chemicals, silica, as a thickener and adsorbent for skin care products and cosmetics, gradually replaces traditional chemical raw materials with the advantages of safety and environmental protection, and the market penetration rate has steadily increased.
Industry insiders said that at present, the domestic silica industry has entered the stage of "differentiated competition", and the contradiction between low-end overcapacity and high-end capacity shortage still exists. In the future, with the implementation of more high-end production lines and the continuous upgrading of technology, domestic silica companies will gradually break the monopoly of foreign enterprises in the high-end field, and at the same time rely on diversified application scenarios to further broaden the market space and promote the high-quality development of the industry.
It is also understood that the production line put into production by Shandong Silicon Technology has also achieved intelligent control, through big data and Internet of Things technology, to achieve accurate monitoring of the whole production process, effectively improve the stability of product quality, and reduce the production cost of tons of products by 8% compared with the traditional production line, truly realizing green, efficient and intelligent production, and providing a model for industry transformation and upgrading.
