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 Manufactured Organic Hydrophobic Fumed Silica SiO2 Powder with CAS No 112945-52-5 1kg MOQ

This hydrophobic fumed silica powder comes from a factory. Its CAS number is 112945-52-5. This material is very fine. It is white powder. The particles are nano-sized. The surface is treated. This makes it hydrophobic. Water does not easily stick to it.

The purity is high. It is at least 99.8% silicon dioxide (SiO₂). The specific surface area is important. It is typically between 90 and 130 m²/g. This large area helps its performance. The bulk density is low. It is around 50 g/L. The powder is light and fluffy.

This silica powder is a great reinforcing filler. It makes rubber products stronger. Tires and industrial rubber goods use it. It acts as a thickener. Paint and coatings need this. It prevents the liquid from dripping. Adhesives and sealants also use it. It controls how they flow. It stops them from sinking. The powder makes the mixture stable. It stops things from separating.

It helps control viscosity. This means it changes how thick the liquid feels. It improves how things stick together. This is good for many industrial uses. The powder is packed carefully. It comes in sealed bags. Common sizes are 5kg, 10kg, or 20kg bags. Larger amounts are possible. The minimum order quantity is just 1kg. This allows small tests or purchases.

Applications of Factory Manufactured Organic Hydrophobic Fumed Silica SiO2 Powder with CAS No 112945-52-5 1kg MOQ

This factory made organic hydrophobic fumed silica powder has CAS number 112945-52-5. We offer a 1kg minimum order quantity. This powder is very fine. It repels water strongly. This makes it useful in many industries. It acts as a thickener and anti-settling agent.

Adhesives and sealants use this silica. It stops the material from sagging during application. It improves the bond strength. It makes the final product more durable. The water resistance is important here.

Coatings and paints benefit from this powder. It helps keep pigments mixed evenly. It prevents hard settling in the can. It improves the finish on surfaces. The flow properties get better. The coating applies smoothly.

Pharmaceuticals need this silica too. It stops powders from clumping together. It helps tablets form correctly. It makes powders flow freely during processing. It keeps moisture away from sensitive ingredients. This ensures product stability.

Industrial applications are common. It is a free-flow agent for powders. It prevents caking in storage. It improves handling of fine materials. It is used in composites like rubber and plastics. It enhances strength and processing.

This hydrophobic fumed silica is a key additive. It solves problems with flow and moisture. It improves product performance. Its versatility makes it valuable across different fields.

5 FAQs of Factory Manufactured Organic Hydrophobic Fumed Silica SiO2 Powder with CAS No 112945-52-5 1kg MOQ

What is hydrophobic fumed silica?
It’s a very fine white powder made mostly of silicon dioxide (SiO2). Factories produce it using a special flame process. This powder doesn’t mix well with water.

What is hydrophobic fumed silica used for?
It’s mainly used to thicken liquids or make powders flow better. You find it in things like paints, coatings, adhesives, and sealants. It also helps stop powders from clumping together. It makes silicone rubber stronger too.

Why is it called hydrophobic?
Hydrophobic means it repels water. The factory treats the silica particles with special chemicals. These chemicals make the silica dislike water. So the powder stays dry and flows easily.

How is hydrophobic fumed silica made?
Factories start by burning silicon tetrachloride vapor in hydrogen and oxygen flames. This creates tiny silica particles. Next, they treat these particles with special chemicals. This treatment makes the silica hydrophobic. Then they collect the fine powder.

Why is the MOQ 1 kilogram?
1 kilogram is the smallest amount we sell. This MOQ helps keep costs reasonable for packaging and shipping. It also suits smaller buyers or those testing the product. Larger orders are available.
