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 nano fumed silica 200 hydrophilic microsphere glass silicon silica gel powder for htv silicon rubber sealant

This nano fumed silica powder is quality 200. It is hydrophilic. This suggests it attracts water. It is made from pure silicon dioxide. The fragments are really tiny microspheres. They resemble fine white powder. The area is big, regarding 200 square meters per gram. This large surface area is crucial. It makes the powder extremely energetic.

It is designed for HTV silicone rubber sealers. HTV means high-temperature vulcanizing. Sealants need enlarging. This powder thickens them well. It acts like a thickener. Sealers remain smooth. They do not trickle or droop conveniently. Workers can use them nicely.

The powder additionally reinforces the sealer. It makes the treated rubber stronger. Tear toughness improves. The sealant stands up to damage better. It lasts longer under anxiety. The powder disperses uniformly in silicone. No globs develop. This maintains the sealant clear or clear. Appearance remains great.

The pureness is high. It mores than 99.8% silicon dioxide. Contaminations are really low. This protects against problems in the sealant. Efficiency remains reliable. The bit dimension is nanoscale. This tiny dimension gives the powder its power. It interacts well with silicone particles.

Hydrophilic nature is very important. It bonds well with silicone polymers. The powder incorporates smoothly. Processing is simpler. Mixing time is much shorter. Suppliers save time. The powder boosts rheology. Circulation residential or commercial properties are much better managed.

It functions well in many HTV silicone sealer kinds. It is a relied on additive. Sealants acquire better application feel. They cure properly. The end product has high quality. Mechanical residential properties are enhanced. Sealers do well popular usages. They manage climate. They withstand chemicals. They preserve versatility in time. Toughness increases.

Applications of nano fumed silica 200 hydrophilic microsphere glass silicon silica gel powder for htv silicon rubber sealant

Nano fumed silica 200 hydrophilic powder is a key ingredient for high-performance HTV silicone rubber sealants. This unique silica powder imitates tiny, strong glass grains. It gets combined into the silicone rubber base. The powder makes the uncured silicone paste thicker. This aids the sealant keep where you use it. It quits the sealant from leaking or drooping on upright surface areas. That’s important during application.

The powder additionally makes the treated silicone sealant a lot stronger. It enhances the rubber structure. The small silica bits bond well with the silicone particles. This gives the final sealer better tear stamina. It also boosts resistance to being pulled apart. Sealers require this strength to last.

This hydrophilic fumed silica type is unique. It keeps the cured silicone sealer looking clear. Various other fillers may make the sealer cloudy or white. This silica allows light pass through easily. You obtain a clear or translucent sealant after healing. That’s typically required for glass or aesthetic applications.

Processing the sealer is much easier too. This powder spreads well in the silicone rubber. It blends smoothly without forming lumps. Employees discover it simpler to deal with throughout production. The sealer streams well into molds or during extrusion. This saves time and effort.

The powder additionally aids the sealant stand up to climate. Sunlight, rain, and temperature level modifications damages many products. This silica boosts the sealant’s capacity to handle these problems. It adds to lasting toughness outdoors. The sealant remains versatile and efficient for years.

You get predictable efficiency batch after set. The powder’s consistent high quality makes certain trustworthy sealant properties. Manufacturers trust it for essential sealing tasks. The sealant bonds well to lots of surface areas like glass, metal, and concrete. It gives a trustworthy, long-lasting seal.

5 FAQs of nano fumed silica 200 hydrophilic microsphere glass silicon silica gel powder for htv silicon rubber sealant

Here are five common questions about nano fumed silica 200 hydrophilic powder for HTV silicone sealant:

What is this powder?
This powder is super fine silica. It comes from burning silicon chemicals. The particles are very small. They form tiny chains and clusters. This powder mixes easily with water.

Why add it to HTV silicone sealant?
It makes the sealant thicker. It stops the sealant from dripping. It helps the sealant keep its shape before curing. It strengthens the final rubber. It improves how the sealant handles stress.

How does “hydrophilic” help?
Hydrophilic means it likes water. This makes it wet faster. It mixes into the silicone paste more easily. You don’t need long mixing times. It avoids clumping better than hydrophobic types.

How much powder should I use?
The amount depends on your sealant formula. It depends on the thickness you need. Common amounts range from 2% to 10%. Start with a small amount. Test the sealant’s flow and strength. Adjust as needed.

Are there handling precautions?
Yes. The powder is very fine. Wear a dust mask. Avoid breathing it in. Wear gloves and eye protection. Work in a well-ventilated area. Keep the powder dry. Store it sealed tightly.
