Advantage
High Purity & Brightness
With SiO2 content>98%and exceptional whiteness, our silica ensures zero color interference, making it perfect for high-end pigments, coatings, and silicone rubber.
High Oil Absorption Value
Features an optimized oil absorption (200-300 ml/100g), providing superior reinforcement in tires and rubber products to improve tensile strength and abrasion resistance.
Precision Matting & Clarity
The high specific surface area and controlled particle size offer excellent matting efficiency and transparency in wood coatings, industrial paints, and printing inks.
Superior Anti-Caking Effect
Its high porosity and fine particle size effectively absorb moisture and oil, keeping feed, food, and chemical powders free-flowing and preventing clumps.

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.
