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 super cas 7631-869-9 industrial grade hydrophilic fumed silica hydrophobic fumed silica nano sio2 silicon dioxide

Meet our commercial grade fumed silica. This material comes in two types. Hydrophilic fumed silica loves water. Hydrophobic fumed silica fends off water. Both types utilize nano-sized silicon dioxide particles. The CAS number is 7631-86-9. This confirms the chemical identity.

The fragments are exceptionally small. They gauge in the nanometer array. This small dimension develops a massive area. Area directly influences efficiency. High surface indicates far better reinforcement. It also boosts enlarging power. These particles imitate tiny sponges.

Our hydrophilic quality soaks up moisture conveniently. It functions well in water-based systems. Believe paints or coatings. It enlarges them effectively. It stops sagging or dripping. It likewise enhances materials. This makes products more powerful. Our hydrophobic quality avoids water. It functions best in oils or solvents. Utilize it in silicone rubber or adhesives. It keeps residential or commercial properties secure in damp conditions. It boosts flow control.

Pureness is vital for industrial use. Our fumed silica fulfills rigorous requirements. It has very low degrees of pollutants. This ensures consistent results batch after set. Uniformity issues for manufacturing. You obtain trustworthy performance whenever.

This silica is a versatile additive. Its primary job is alteration. It alters just how liquids behave. It makes thin liquids thicker. It prevents clearing up in suspensions. It adds toughness to soft materials. It regulates circulation buildings precisely. Different industries depend on it. Sealers and adhesives need its power. Plastics and compounds benefit too. Rubber products acquire toughness. Also inks and coatings utilize it. Efficiency depends upon the quality. Select hydrophilic for water supply. Pick hydrophobic for oil or solvent systems. Both deal excellent support. Both offer exceptional rheology control. Manage this powder meticulously. Follow conventional safety treatments.

Applications of super cas 7631-869-9 industrial grade hydrophilic fumed silica hydrophobic fumed silica nano sio2 silicon dioxide

Below’s what this powder does. Industrial grade fumed silica is extremely great silicon dioxide. CAS number 7631-86-9 identifies it. The powder is available in two main kinds. One kind loves water. We call it hydrophilic. The other kind drives away water. That’s hydrophobic fumed silica. Both types are incredibly tiny bits. This nano size provides unique powers.

Hydrophilic fumed silica acts like a thickener. It thickens liquids effectively. Believe paints and layers. It makes them apply efficiently. It stops dripping. In adhesives and sealers, it regulates just how they stream. It aids them stick right. It makes them more powerful. This powder stops clumping too. In powders like flavors or cement, it keeps them flowing openly. It stops them sticking.

Hydrophobic fumed silica is different. It hates water. This makes it excellent for waterproofing. Add it to silicone rubber. The rubber remains flexible. It keeps water out. It makes the rubber last much longer. Use it in finishings for electronics. It protects them from wetness damage. This powder aids liquids blend much better. Oil and water generally separate. This powder aids them blend. It makes steady combinations. Discover this in cosmetics and some food products. Plastics benefit also. It makes surfaces much less sticky. It makes plastics much easier to handle. It enhances scrape resistance.

Medication production utilizes this powder. It helps regulate just how tablets circulation during making. It guarantees consistent pill dimension. It helps medicines liquify properly in the body. Both hydrophilic and hydrophobic types are crucial. They address lots of commercial issues. They make items perform far better. They make products last much longer.

5 FAQs of super cas 7631-869-9 industrial grade hydrophilic fumed silica hydrophobic fumed silica nano sio2 silicon dioxide

What is this fumed silica product?
It is industrial-grade nano silicon dioxide. The CAS number is 7631-86-9. This powder comes in two types. One type attracts water easily. The other type repels water strongly. Both are super fine particles made through a special burning process.

Why offer both hydrophilic and hydrophobic types?
Different jobs need different properties. The water-loving type mixes into liquids easily. It thickens products like paints or adhesives well. The water-repelling type works best in plastics or rubbers. It keeps strength even in wet conditions. Choosing the right type matters for performance.

How small are these particles?
They are nano-sized. This means extremely tiny. Particle size is measured in nanometers. Small size gives high surface area. High surface area makes the silica very effective. A little powder does a lot of work in your product.

Where is this silica used?
Many industries rely on it. Common uses include silicone rubber, paints, coatings, printing inks, adhesives, and sealants. In rubber, it makes things stronger and last longer. In coatings, it prevents sagging and improves durability. In adhesives, it controls thickness and stability.

Is it safe to handle?
Handle it with care. Wear proper protection. Use gloves, safety glasses, and a dust mask. Avoid breathing the fine dust. Avoid skin contact. Keep it away from your eyes. Store it in a cool, dry place. Check the safety sheet for full details before use.
