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 High Quality Sio2 Paint And Rubber Hydrophilic Fumed Silica 7631-86-9 Silicon Dioxide

This hydrophilic fumed silica, called Silicon Dioxide (SiO2) with CAS 7631-86-9, is a top-quality powder. It comes from shedding silicon tetrachloride in a hydrogen-oxygen fire. This approach produces extremely pure silica. The powder has a big area. This big area is crucial for its efficiency. The typical area is in between 150 and 300 square meters per gram. It uses outstanding thickening power. It manages the flow of fluids extremely well. This implies it quits settling and separation. It makes items steady.

Purity is a major focus. The product has at least 99.8% SiO2. This high purity makes sure constant outcomes. It avoids unwanted reactions. The pH degree is neutral. It usually rests between 3.6 and 4.3. This neutral pH makes it safe for several uses. It will not damage various other products. The powder is extremely white. It has an intense look. This is necessary for end product shade. The powder is likewise really great. It distributes easily into liquids.

Its major work is enlarging and reinforcing. In paints and finishings, it protects against trickling. It provides a smooth surface. It stops pigments from sinking. In rubber substances, it makes the rubber more powerful. It improves tear resistance. It aids the rubber last much longer. This silica is hydrophilic. It enjoys water. This makes it excellent for water-based systems. It functions well in adhesives and sealants too. It controls their dampness. It assists them set appropriately. You find it in personal treatment things. It thickens lotions and gels. It makes tooth paste smooth. It’s an essential part of numerous daily products. It provides trusted thickening and support.

Applications of High Quality Sio2 Paint And Rubber Hydrophilic Fumed Silica 7631-86-9 Silicon Dioxide

This top quality hydrophilic fumed silica, called silicon dioxide (CAS 7631-86-9), is a key active ingredient for many sectors. Its fine bits and one-of-a-kind surface buildings use real efficiency boosts. In paints and coatings, it imitates an effective thickener. This protects against the paint from dripping or sagging on vertical surface areas. It likewise assists the paint flow efficiently during application, giving a better finish. The silica fragments strengthen the paint movie. This makes the finish much harder and extra scratch-resistant. It also improves the paint’s capacity to stand up to sunlight, rain, and other weather. Colored surfaces last longer and look far better. The hydrophilic nature suggests it mixes easily with water-based systems. This is very important for numerous contemporary, eco-friendly paints.

Rubber items acquire substantial benefits from this hydrophilic fumed silica. It is an effective reinforcing filler. Adding it makes rubber compounds a lot more powerful and a lot more resilient. Tires, shoe soles, industrial hoses, and seals all advantage. It improves the rubber’s resistance to tearing and abrasion. Points like tires last longer and deal with use better. The silica also aids the rubber resist heat accumulation during usage. This decreases aging and fracturing. It improves the rubber’s grasp, particularly in damp problems. This is essential for tire safety. The hydrophilic surface area engages well with common rubber handling aids. It spreads effectively within the rubber mix. This makes certain constant top quality and efficiency in the end product. Manufacturers count on it for high-performance rubber products.

5 FAQs of High Quality Sio2 Paint And Rubber Hydrophilic Fumed Silica 7631-86-9 Silicon Dioxide

This High Quality SIO2 Paint and Rubber Hydrophilic Fumed Silica (CAS 7631-86-9) is pure silicon dioxide. It’s a fine white powder. People use it a lot in paints, coatings, and rubber compounds. Here are common questions:

What exactly is this Hydrophilic Fumed Silica?
It’s a synthetic form of silicon dioxide. We make it by burning silicon tetrachloride in a hydrogen-oxygen flame. This creates tiny particles. These particles form chain-like structures. The surface has many hydroxyl groups. This makes it attract water easily. That’s why it’s called “hydrophilic”.

Why use it in paints and coatings?
It controls flow. It stops paint from sagging on vertical surfaces. It prevents settling of pigments in the can. It gives the paint body without making it too thick. This makes application smoother. The paint levels out nicely. You get a better finish.

How does it help rubber products?
It reinforces rubber. It makes rubber stronger and more tear-resistant. It improves processing. The rubber compound flows better into molds. It acts as a thickener for silicone rubber. This keeps the rubber stable before curing. It helps the rubber keep its shape.

Is it safe to handle?
Yes, generally. It carries the CAS number 7631-86-9. Always check the specific Safety Data Sheet (SDS) for your product batch. Handle it carefully. Avoid breathing in the dust. Use proper dust masks. Wear gloves and eye protection. Good ventilation is important. Follow standard industrial hygiene practices.

What makes this grade “high quality”?
Consistency is key. Every batch performs the same. Particle size distribution is tightly controlled. Surface area and purity are high and reliable. This ensures predictable results in your formulas. You get the performance you expect every time.
