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 Fumed Silica Nano Silica Powder Silicon Dioxide silicon dioxide SiO2 Hydrophobic Fumed Silica

Fumed silica powder is silicon dioxide, SiO2. It comes as a really fine white powder. People make it through a special high-temperature process. This procedure creates little bits. These fragments are extremely little, gauged in nanometers. This nano dimension provides the powder unique top qualities.

This certain type is hydrophobic fumed silica. Hydrophobic implies it wards off water. It does not take in moisture conveniently. This makes it excellent for uses where water is an issue. Normal fumed silica brings in water.

Secret specifications matter for this powder. Surface area is extremely crucial. It informs you how much surface area the little bits expose. High surface area prevails, like 200 square meters per gram. Bit dimension is nano-sized. Mass thickness is reduced. The powder feels light and cosy. The powder has a neutral pH around 4.0. Dampness web content is maintained really reduced. Loss on drying out is usually under 1.5%.

Hydrophobic fumed silica is a powerful thickener. It makes fluids thicker without altering them a lot. It works in both water-based and solvent-based systems. It protects against drooping in paints and coverings. It acts as a reinforcing filler. It makes rubbers and plastics more powerful. It boosts flow buildings. It quits powders from clumping with each other. It keeps things free-flowing. It controls viscosity. This assists during application. It is chemically inert. It does not react conveniently. It provides good stability.

This powder is useful in lots of industries. It operates in silicone rubber and sealers. It thickens paints, coatings, and inks. It avoids caking in food powders and drugs. It assists in adhesives and materials. It is used in cosmetics and personal care products. The hydrophobic nature is crucial. It guarantees efficiency in damp problems. It prevents undesirable gelling with water. It provides consistent outcomes.

Applications of Fumed Silica Nano Silica Powder Silicon Dioxide silicon dioxide SiO2 Hydrophobic Fumed Silica

Hydrophobic fumed silica powder discovers usages in several markets. This treated silicon dioxide (SiO2) acts in different ways than regular silica. Its surface area fends off water. This property provides unique advantages.

Rubber products rely greatly on it. Adding hydrophobic fumed silica makes rubber a lot stronger. It enhances tear resistance substantially. Tires last longer due to this. Seals and gaskets carry out better as well. The powder also helps handling rubber blends.

Coatings and paints require it. Hydrophobic fumed silica prevents settling of solids in the canister. It stops pigments from clumping together. Applied finishings get better toughness. They withstand water damage successfully. Surface areas stay cleaner for longer periods.

Adhesives and sealants utilize this powder. It manages the thickness, the thickness. The material stays where you apply it. It does not droop or escape upright surface areas. Bond toughness frequently boosts. The last seal continues to be adaptable and reputable.

Pharmaceuticals use hydrophobic fumed silica. It makes powder blends flow easily. Equipments fill up capsules efficiently. Tablet manufacturing ends up being extra constant. Active components blend evenly throughout the powder. This guarantees precise dosing each time.

Cosmetics gain from its structure. Lotions really feel smooth and non-greasy. Powders use evenly on the skin. Make-up stays longer. The silica soaks up excess oils delicately. Products preserve their desired consistency well.

Printing inks utilize it too. Hydrophobic fumed silica manages ink circulation. Publish high quality keeps sharp and clear. Shades stay vibrant. Smearing is decreased significantly. The ink adheres properly to different products.

Food in some cases include percentages. It serves as an anti-caking agent. Powdered foods stay loose and free-flowing. Flavors pour quickly from the container. Wetness doesn’t trigger clumping. Life span extends visibly.

5 FAQs of Fumed Silica Nano Silica Powder Silicon Dioxide silicon dioxide SiO2 Hydrophobic Fumed Silica

What is hydrophobic fumed silica?
It’s a very fine white powder made of silicon dioxide (SiO2). We create it at high temperature. This process forms tiny particles. These particles link into branched chains. The chains create a large surface area. This powder does not like water. It repels water effectively.

Why is it called hydrophobic?
Hydrophobic means “water fearing”. The raw silica particles get treated. We coat them with special chemicals. These chemicals are often silanes. The coating changes the surface. Water cannot stick to it easily. The powder stays dry. It flows better in humid conditions.

Where do people use this material?
It goes into many products needing thickening or reinforcement. It thickens paints and coatings. It makes silicone sealants flow less. It reinforces plastics and rubbers. It controls powder flow in cosmetics. It stabilizes adhesives. It prevents clumping in food powders. It helps make battery electrodes.

What makes it useful?
Its structure gives key properties. The large surface area interacts strongly. This interaction thickens liquids without heat. It acts like a thickener. It makes liquids less runny. The coating prevents water absorption. Performance stays consistent. The powder stays free-flowing. It improves mechanical strength in solids. It adds reinforcement.

Is it safe to handle?
Handle it carefully like any fine powder. Avoid breathing the dust. Use good ventilation. Wear a dust mask. Wear eye protection. Skin contact is usually low risk. Wash skin after handling. Check the safety data sheet for your specific grade. Follow all handling instructions given. Store it in a dry place. Keep the container closed.
