Our Silica is a fine white powder used in rubber, coatings, feed additives and other industrial formulations. With SiO2 content above 98% and a BET surface area of 160–190 m2/g, it is suitable for applications where purity, particle performance and consistent quality are important.
We supply standard industrial grades in 25 kg bags and jumbo bags, with packaging and shipment options arranged according to order quantity and destination.
Product Features
High SiO₂ Content
SiO2 content is not less than 98.0% on a dry basis. The white powder is suitable for formulations where a clean appearance and stable silica content are required.
Controlled Surface Area
BET surface area is controlled at 160–190 m2/g, providing a consistent surface for applications in rubber, coatings and other formulations.
Suitable for Rubber and Coatings
The combination of silica content, surface area and oil absorption makes this grade suitable for rubber products, coatings, paints and printing inks.
Powder Flow & Moisture Control
The fine porous powder can absorb moisture and oil, which makes it useful as an anti-caking and carrier material in powdered products.

FAQ
Q: What is the recommended storage condition for Silica?
A: Silica should be stored in a cool, dry, and well-ventilated area. It is highly absorbent, so keep the packaging tightly sealed and away from moisture or direct sunlight to prevent clumping.
Q: What are the standard packaging options?
A: Our standard packaging is 20kg or 25kg multi-layer kraft paper bags or valve bags. For bulk shipments, we also provide 500kg or 1,000kg jumbo bags (super sacks) to simplify your unloading process.
Q: What is the best way to transport Silica?
A: Standard dry containers are recommended for sea freight. Ensure the container is clean and dry before loading. During inland transportation, the cargo must be covered to protect it from rain and humidity.
Q: What is the shelf life of the product?
A: If stored in its original, unopened packaging under dry conditions, Silica generally has a shelf life of 24 months from the production date.
Q: Are there any safety precautions for handling?
A:Since Silica is a fine powder, we recommend using dust masks, safety goggles, and gloves during handling to avoid dust inhalation and skin dryness. It is non-toxic but can be an irritant to the respiratory system.
