Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of Factory Precipitated Hydrophilic SiO2 White Carbon Black Fumed Silica Dioxide Oxide

This is factory-made precipitated hydrophilic silica. People often call it white carbon black or fumed silica dioxide. It’s a very fine white powder. The powder is super light and fluffy. It feels almost like flour. This silica is hydrophilic. That means it loves water. It absorbs moisture from the air easily. This is important for how it works.

We make this silica using a precipitation process in our factory. We control this process carefully. This control gives us consistent quality. Every batch meets the same high standard. The powder has a very large surface area. This large area makes it very active. It interacts strongly with other materials.

The particles are extremely small. They are also very porous. These tiny particles act like a strong thickener. They thicken liquids very effectively. Only a small amount is needed. This silica also works as a great anti-settling agent. It stops solids from sinking in liquids. It keeps mixtures stable and uniform. The powder acts like a carrier too. It holds liquids and helps distribute them evenly.

This silica is very versatile. It finds many uses across different industries. It is a key ingredient in silicone rubber. It makes the rubber much stronger. It improves the rubber’s tear resistance significantly. You find it in coatings and paints. It controls how thick they are. It prevents sagging on vertical surfaces. It helps in printing inks. It adjusts the ink’s flow and prevents settling. Adhesives and sealants use it. It provides structure and prevents dripping. It is common in personal care items like toothpaste. It gives toothpaste its smooth texture and body. It acts as a free-flow agent for powders. It stops powders from clumping together. It keeps them dry and easy to pour. It is used in food and pharmaceuticals. It helps process powders and prevents caking.

Applications of Factory Precipitated Hydrophilic SiO2 White Carbon Black Fumed Silica Dioxide Oxide

Factory Precipitated Hydrophilic SiO2 White Carbon Black is important stuff. People call it fumed silica too. It does many jobs well. This powder makes things thicker. It stops liquids from dripping. It also makes stuff stronger.

This silica is great for glue and sealants. It stops the glue from running down when you put it on a wall. It makes the glue stay put. The glue also gets stronger. It lasts longer.

Paint and coatings need this silica. It stops the color bits from sinking to the bottom of the can. Your paint stays mixed. It makes the paint spread nicely. It doesn’t sag on the wall. The finish looks good.

Plastic products use this silica. It makes the plastic stronger. It stops the plastic from breaking easily. Plastic parts last longer. It helps the plastic flow right when they make it. They get fewer bad pieces.

Rubber goods need silica. Tires use a lot. It makes the rubber tough. The tires grip the road better. They last longer too. It helps other rubber parts perform well.

Cosmetics and toothpaste use this silica. It makes creams smooth. It stops toothpaste from getting watery. It feels nice on your skin. It helps sunscreen spread evenly.

Pharmaceuticals use it sometimes. It helps make pills. It controls how fast the medicine comes out. It keeps powder flowing freely in machines. They make pills faster.

5 FAQs of Factory Precipitated Hydrophilic SiO2 White Carbon Black Fumed Silica Dioxide Oxide

What exactly is hydrophilic silica?
It’s a fine white powder. Factories make it through a chemical process. This material is very pure silica dioxide. People often call it white carbon black or fumed silica. It looks like powdered sugar. It feels light and fluffy.

Why use hydrophilic silica in products?
It does important jobs. It thickens liquids. It stops mixtures from separating. It makes solids like powders flow better. It helps liquids hold their shape. This makes products work well and last longer.

How does hydrophilic silica make things thicker?
The tiny silica particles link together. They form a loose network inside liquids. This network traps the liquid. It makes the mixture resist flowing easily. You get a thicker paste or gel. This works even with a small amount of silica.

Is this silica safe?
Yes, generally it is safe. It is non-toxic. Major food safety groups approve it for certain uses. It is common in food, medicine, and cosmetics. Always check the safety sheet for your specific grade. Avoid breathing in the fine dust.

How should we store and handle it?
Keep it dry. Moisture makes it clump. Store bags in a cool, dry place. Seal bags tightly after opening. Wear a dust mask when handling large amounts. The powder is very light. It can float in the air easily. Prevent spills to avoid dust clouds.
