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 supply Nano Fumed Hydrophobic Silica cas 112945-52-5 Sio2

This hydrophobic fumed silica comes right from the factory. Its CAS number is 112945-52-5. The main part is silicon dioxide (SiO2). The SiO2 pureness is really high, constantly over 99.8%. This product is treated to be hydrophobic. Water does not like it. This makes it push back dampness.

The surface is large, in between 90 and 130 square meters per gram. This large surface area aids it function well. The particles are very small, only 7 to 16 nanometers. This great size lets it blend conveniently. The bulk thickness is reduced, around 30 to 60 grams per liter. The touched density is higher, regarding 40 to 70 grams per liter. It looks pure white.

This silica is outstanding for making powders flow freely. It quits powders from clumping. It quits powders from caking. It acts like a thickener in fluids. It makes liquids thicker without altering them much. It strengthens silicone rubber. It makes rubber more powerful. It helps control exactly how fluids flow. It works well in paints, finishings, inks, adhesives, and sealers. It makes these products much better.

It works well in plastics and composites. It improves their toughness. It enhances their handling. It aids in cosmetics. It helps in pharmaceuticals. It stops resolving. It helps things spread equally. Its water-repelling nature is vital for outside use. It quits moisture damages. It maintains performance steady in damp conditions. This silica is dependable. It satisfies stringent quality standards. It awaits demanding industrial tasks.

5 FAQs of Factory supply Nano Fumed Hydrophobic Silica cas 112945-52-5 Sio2

What is Nano Fumed Hydrophobic Silica?
It’s a special powder. This powder is made of very tiny particles of silicon dioxide (SiO2). We make it using a special burning process. Then we treat it to make it repel water. This treatment makes it hydrophobic. Its official chemical name links to CAS number 112945-52-5.

What makes this silica special?
Its key feature is repelling water. Water beads up and rolls off it. This silica also has a huge surface area. The particles are very small. These properties help it thicken liquids. It makes stuff stronger. It stops liquids from flowing too easily. It helps control how thick or thin a material is.

Where do people use this hydrophobic silica?
People use it in many industries. It’s common in sealants and adhesives. It makes them stronger and last longer. It’s used in paints and coatings. It helps them resist water and stay durable. It thickens printing inks and resins. It helps make rubber products better. It works well in plastics and some cosmetics too.

Is this silica safe to handle?
Handle it carefully. Wear gloves and a dust mask. Wear safety glasses. Avoid breathing the dust. Keep it away from your skin and eyes. Good ventilation is important. Read the safety sheet before using it. Follow all safety rules. Store it properly.

How do you package and store it?
We ship it in strong bags. We use sealed plastic bags inside cardboard drums. We use sealed plastic bags inside woven sacks. Store the bags in a cool, dry place. Keep them tightly closed. Keep them away from moisture. Moisture can ruin its hydrophobic properties.
