1. Is your company a manufacturer or a trade company?
A Manufacturer. We’ve been researching and manufacturing fumed silica for 20 years. We are the largest 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 or trichloromethylsilane in the flame of hydrogen and oxygen. Our main raw material is silicon tetrachloride, and secondary is trichloromethylsilane.
 
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 coating, 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 are the earliest fumed silica manufactures with independent R&D in China, which guarantees our product stabilization.
Largest Manufacturer : Our annual output of hydrophilic product is 8,000 tons and hydrophobic ones is 1,000 tons.
Strong R&D Team: Besides from our own R&D institute and application& technology department, we’ve build research center with Sichuang University and Wuhan University, both are top-tier university in China.
Leading Authority: We have already been the influential enterprise in silicon industry in China. Doctor Wang Yuelin, actual controller of Hifull, is the leader of the Sino-Germany  project ISO18473-3 << Fumed Silica for Silicon Rubber>> and he is granted the Outstanding Contribution Award by the committee.
We have complete grade/model of fumed silica, including 4 hydrophilic grades and 9 hydrophobic grades.
 
6. What are the grades you have?
Hydrophilic Grade: HL-150 / HL-200 / HL-300 / HL-380.
Hydrophobic Grade: DDS Treated — HB-151/ HB-152  ; PDMS Treated  — HB-139 ; HMDS Treated —  HB-132 / HB-135 / HB-612/ HB-615 / HB-620 / HB-630.
 
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?
