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 and low Nano Hydrophilic Fumed Silica SiO2 silicon dioxide fumed silica

Top Quality Low Nano Hydrophilic Fumed Silica (SiO TWO)

Pure Performance in Every Fragment

Our hydrophilic fumed silica is made from high-purity silicon dioxide (SiO TWO). It features an extremely little particle dimension– well below 100 nanometers. This gives it excellent surface activity and solid thickening power. The material is created utilizing a flame hydrolysis process. This approach makes sure consistent top quality and consistent fragment structure.

Why choose this fumed silica?
It blends quickly into water-based systems. No extra treatment is needed. The bits bond well with wetness airborne or fluid. This makes it excellent for layers, adhesives, sealants, and lots of various other applications. It also enhances suspension stability and protects against settling of solid components.

Key physical characteristics:
– Specific area: 200– 400 m ²/ g.
– Ordinary main fragment dimension: 7– 40 nm.
– Bulk density: low, generally 30– 80 g/L.
– pH worth (in 4% diffusion): around 3.5– 4.5.
– Loss on drying out: under 1.5% at 105 ° C.

This fumed silica is free from included surfactants or organic modifiers. It remains secure during storage space and performs reliably under regular handling problems. Its fine structure streams smoothly and disperses promptly when mixed correctly.

Producers use it to regulate viscosity, avoid drooping, and improve mechanical strength. It works well in paints, inks, cosmetics, pharmaceuticals, and specialty chemicals. Due to the fact that it is hydrophilic, it incorporates fast right into polar systems without clumping.

We pack the item in sealed multi-layer bags or drums. This protects it from wetness and maintains its performance undamaged up until usage. All batches meet rigorous quality assurance standards. Each delivery features complete documents and technological support.

Applications of High quality and low Nano Hydrophilic Fumed Silica SiO2 silicon dioxide fumed silica

Applications of High-Quality, Low-Nano Hydrophilic Fumed Silica (SiO TWO)

Enlarging and Rheology Control

Top quality hydrophilic fumed silica is widely made use of to regulate circulation and structure in fluids. It assists stop settling of strong fragments in paints, finishes, and adhesives. When included small amounts, it gives items the appropriate thickness without altering their clearness or efficiency.

Anti-Caking Representative in Powders

This silica keeps dry powders free-flowing. It quits globs from forming in preservative, drugs, and cosmetics. Its great bit dimension makes sure also mixing and long service life. The product satisfies strict safety requirements for usage in durable goods.

Reinforcement in Silicone Rubbers

In silicone-based items like seals, gaskets, and clinical tubing, fumed silica adds strength and toughness. It enhances tear resistance and preserves versatility with time. Only a percentage is needed to get strong results.

Matting Agent in Coatings

Fumed silica produces a soft, non-reflective surface in paints and varnishes. This matte surface is popular in furniture, auto, and building finishes. The effect remains constant under various lights problems.

Stabilizer in Adhesives and Sealants

It stops fluid adhesives from dripping or drooping after application. This makes upright bonding simpler and cleaner. The silica also assists preserve bond stamina throughout temperature adjustments.

Provider for Energetic Active Ingredients

As a result of its big area, fumed silica holds and gradually launches energetic substances. This is useful in agrochemicals, scents, and individual care items. It ensures also circulation and far better performance.

All these uses depend on the material’s purity, regular fragment dimension, and solid communication with other materials. Its hydrophilic nature suggests it functions well in water-based systems without extra therapy.

5 FAQs of High quality and low Nano Hydrophilic Fumed Silica SiO2 silicon dioxide fumed silica

Frequently Asked Questions About High-Quality, Low-Nano Hydrophilic Fumed Silica (SiO₂)

What is hydrophilic fumed silica?

Hydrophilic fumed silica is a fine white powder made from silicon dioxide (SiO₂). It is created through a high-temperature process that forms tiny particles. These particles naturally attract water, which makes the material “hydrophilic.” This type of silica is very pure and has strong thickening and anti-settling properties.

Why choose low-nano fumed silica?

Low-nano means the primary particle size stays above typical nano thresholds. This helps meet safety and regulatory standards in many industries. It also reduces potential health concerns linked to ultrafine nanoparticles while keeping excellent performance in applications like coatings, adhesives, and cosmetics.

How does it improve product performance?

This silica boosts viscosity without changing the chemical makeup of your product. It stops solids from sinking in liquids and keeps mixtures stable over time. In paints and inks, it prevents sagging. In cosmetics, it gives a smooth feel and helps powders flow evenly.

Is it safe to use?

Yes. Our hydrophilic fumed silica meets international quality and safety guidelines. It contains no added chemicals and is free from heavy metals. Because it uses low-nano particles, it offers a safer profile for handling and end-use, especially in personal care and food-contact applications.

How should it be stored and handled?

Store the powder in a dry, cool place with the container tightly closed. Keep it away from moisture since it absorbs water from the air. Use standard dust control measures during handling—like masks and ventilation—to avoid breathing in fine particles. Always follow local safety rules when working with fine powders.
