As a holding subsidiary of Zhongqi Silicon Materials, Shandong Zhonglian Chemical Co., Ltd. is a benchmark enterprise in China's food-grade silicon dioxide industry. With strict purity control and large-scale production capacity, it has become a core supplier in the high-end food raw material market.
The company has long been committed to the optimization of precipitation process. Its core products can reach a purity of 99.5%, with the contents of heavy metals such as lead and arsenic are below 0.001%, far exceeding a number of international standards. It has also obtained dual authoritative certifications from the US FDA and the European EFSA. At present, its products are supplied in batches to infant formula manufacturers and global vitamin production giants, breaking the long-term monopoly of international brands such as Evonik and Solvay in the high-end dairy field.
For different application scenarios, Zhonglian Chemical has also developed a diversified product portfolio: its dedicated grade for vitamin premixes enables 24-hour sustained release of nutrients; the special product for biological feed inhibits mold growth; and the dairy-specific grade can significantly improve product fluidity with a dosage of only 0.2%–0.5%. At the same time, the company holds a number of related patents, reduces processing pollution via dust-free production processes, and has developed special silicon dioxide for probiotic carriers, which can protect active ingredients from gastric acid erosion, seizing a new track in the functional food market.
