FAQs
What is silicon dioxide and what are its main uses?
Silicon dioxide is a white, amorphous powder based on silica, featuring high specific surface area, excellent reinforcing properties and chemical stability. It is widely used in rubber (as a reinforcing agent for tire and rubber products), plastics (to improve mechanical properties), coatings (to enhance scratch resistance), toothpaste (as an abrasive), and cosmetics industries.
Which regions are the main exporters of silicon dioxide ?
The main exporting regions include China (with large production capacity and abundant raw material reserves), the United States, Germany, and Japan. These areas dominate global supply due to mature production technologies and consistent product quality.
What quality standards should I pay attention to when importing silicon dioxide?
Key parameters include: specific surface area (150-300 m²/g for reinforcing grades), particle size distribution (D50<20 nm for premium products), moisture content (<1.5%), pH value (5-7), and impurity content (low heavy metal levels). Certifications like ISO 9001.
How is silicon dioxide packaged for international transportation?
It is usually packaged in 25kg paper bags with inner plastic liners; for large orders, 500kg/1000kg bulk bags or bulk shipping are available. It is critical to mark product specifications, batch numbers, and safety labels (e.g., "non-hazardous goods") on the packages.
What are the common trade terms in silicon dioxide trade?
Common terms include FOB (Free On Board), CIF (Cost, Insurance and Freight), and EXW (Ex Works). The selection depends on negotiations between buyers and sellers regarding transportation responsibilities and costs.
What documents are required for importing silicon dioxide?
Required documents include commercial invoice, packing list, bill of lading (B/L), certificate of origin, and quality inspection report.
What payment terms do silicon dioxide suppliers commonly accept?
Suppliers usually accept letters of credit (LC), telegraphic transfer (TT), or secure payment platforms (e.g., Alibaba Trade Assurance). The standard practice is to prepay 30% as a deposit, and the balance is paid before shipment.
Can silicon dioxide be customized for specific industrial uses?
Yes, suppliers offer tailored grades based on client needs, such as:
Reinforcing silicon dioxide (for high-strength rubber products like tires).
Hydrophobic silicon dioxide (for improved dispersion in oil-based coatings).
Ultra-fine silicon dioxide (for matte effects in cosmetics).
