Frequently Asked Questions

What is the difference between precipitated and fumed silica?

Precipitated silica is produced by chemical precipitation and is cost-effective for high-loading applications. Fumed silica (pyrogenic) is made by flame hydrolysis, offering higher purity, surface area, and reinforcement at lower dosages.

Are your food and feed grade silicas certified?

Yes. Our food grade silica complies with FDA 21 CFR §172.480 and EU 231/2012. Feed grade products meet relevant safety standards. We provide FAMI-QS and SGS reports upon request.

Can you customize silica products?

Absolutely. We offer customization in particle size, surface area, surface treatment (e.g., hydrophobic modification), and packaging. Our R&D team works closely with clients to develop tailored solutions.

What regions do you export to?

We export globally, including North America, Europe, Southeast Asia, India, and South America. Our logistics team ensures timely and secure delivery via sea, air, or land.

Do you provide samples?

Yes, we offer free samples for qualified customers. Please contact us through the official website to request product samples and technical data sheets.
