A few years ago, premium toothpaste silica raw materials were mostly imported, with high prices and unstable lead times. 2026 data puts the domestic substitution rate for toothpaste silica at 76%, as domestic products have improved rapidly in technology and quality.
Zhongqi Silicon targets the mid-to-high-end market. We've been producing precipitated silica for nearly 20 years, with a team of over ten R&D engineers continuously refining processes and upgrading product performance. We've served many large food and daily chemical enterprises, and our quality is validated by long-term cooperation with leading customers.
On core metrics — transmittance, fluoride compatibility, RDA abrasion — our grades reach the level of premium overseas equivalents and can be used as direct drop-in replacements without major reformulation. Procurement cost is 20–30% lower than comparable imports, and we ship domestically from stock with no ocean freight wait. We can also customize particle size and oil absorption to match your formulation, for even better compatibility.
Imported raw materials generally have 30–45 day lead times, and may face delays when overseas production fluctuates. We run two automated production lines with ten-thousand-ton annual capacity, so even large orders ship reliably. For detailed performance parameters and test reports, see the full descriptions in our product section.
If you're looking to optimize procurement costs and shorten supply cycles, test samples side by side. More often than not, domestic premium grades can fully meet your requirements.
