1.Is your company a manufacturer or a trade company?
A Manufacturer. We’ve been researching and manufacturing fumed silica for 30 years. We are the top manufacturer of fumed silica with well-developed and stable manufacturing process in China

2.What’s the main raw material?
Fumed silica is synthesized by the pyrohydrolysis of silicon tetrachloride in the flame of hydrogen and oxygen. Our main raw material is silicon tetrachloride.

3.What’s the main applications?
Fumed silica is mainly applied in the field of HTV, RTV, electronic liquid adhesives, adhesives, defoaming agent, ink and coatings, food and drugs, farm chemical, animal-feeding, paintings and so on.

4. What’s the related effects of fumed silica?
When fumed silica is used as filler or additives, it helps in thickening, reinforcement, transparency, free-flow, thixotropy, dielectric properties, anti-settling, heat insulation and anti-sagging.

5. Compared with other manufacturers, What’s the advantages you have?
Quality Stabilization: We got the certificate of manufacture in Zhejiang with the standard T/ZZB 1420-2019, which represents the highest quality standard in China.
Largest Manufacturer: Our annual output of hydrophilic product is 8,000 tons.
Leading Authority: We have already been the influential enterprise in silicon industry in China.

6. What are the grades you have?
Hydrophilic Grade: FST-150/FST-200/FST-380/FST-430

7. What’s the price of your product?
Price is based on the actual grade. When price of raw material fluctuates, we may adjust the price accordingly, please enquire before placing orders.

8. What’s the payment terms?
Mainly T/T, L/C and D/P, actual payment terms please check with sales when placing orders.

9. How long it takes to arrange delivery after placing order?
We will arrange delivery immediately according to manufacturing schedule and condition. Due to shipping schedule or other factors, please check with sales when placing orders.
