Representative Cases
•Passed Nestlé on-site audit (Oct 2025) and became a certified supplier approved for pet food and food wet/dry mixing scenarios.
•Decade-long COFCO partnership guarantees stable tomato powder flowability.
•Yihai Kerry refining: adsorbent with customized pore structure and high specific surface area removes phospholipids and trace metals, improving transmittance and reducing clay and crude-oil loss.
•HaiDiLao beef tallow: optimized particle size raises filtration efficiency by 40%, enabling anhydrous degumming and less wastewater.
•Zoilsil58GS for Snow Beer and Budweiser selectively adsorbs sensitizing proteins and polyphenols as a filter aid, preserving foam and malt flavor.
Applications
Anti-caking silica prevents powder caking and improves flowability. Adsorbent silica removes impurities from liquid systems. Pharmaceutical excipient supports drug loading and gliding. Toothpaste-grade balances cleaning and stability. Cosmetic-grade adjusts skin feel. Pet-feed preserves nutrition and palatability. Antiblock masterbatch serves PET, BOPP and CPP films.
