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.

Requirements of Silicon Dioxide 200 Fume Silica White Powder (SiO ₂)

Item Introduction

Silicon Dioxide 200 is a high-purity fumed silica in fine white powder form. It is made via fire hydrolysis of silicon tetrachloride in a hydrogen-oxygen flame. This process develops amorphous, nano-sized bits with solid thickening and anti-settling properties.

Key Characteristics

Pureness: Minimum 99.8% SiO ₂.
Appearance: Free-flowing white powder.
Bulk Thickness: Roughly 50– 100 g/L.
Certain Area: Around 200 m TWO/ g (BET technique).
Loss on Drying: Not greater than 1.5% at 105 ° C for 2 hours.
pH Value: In between 3.6 and 4.6 in a 4% dispersion.

Performance Conveniences

This fumed silica works well as a thickener, enhancing filler, and flow aid. It helps control thickness in fluids and avoids strong bits from settling. The powder likewise boosts the mechanical strength of rubber and plastics. In finishings and adhesives, it quits drooping and increases toughness. As a result of its tiny fragment dimension and big surface area, it disperses evenly in numerous systems.

Usual Applications

Silicon Dioxide 200 is used in paints, inks, adhesives, sealants, cosmetics, drugs, and food-grade products. It is also contributed to silicone rubber, epoxy materials, and industrial lubricating substances. Its high pureness makes it safe for delicate usages where contamination need to be prevented.

Handling and Storage space

Store in a dry, trendy place away from moisture. Maintain containers snugly shut when not in use. Usage standard dust control actions during dealing with to stay clear of breathing. Put on gloves and safety glasses as a fundamental safety measure.

Applications of Silicon Dioxide 200 Fume Silica White Powder Sio2

Applications of Silicon Dioxide 200 Fume Silica White Powder (SiO ₂)

Enhancing Performance in Building And Construction Materials

Silicon Dioxide 200 Fume Silica is widely made use of in high-strength concrete and cement-based items. It fills up little voids in between bits, making the mix denser and more powerful. This leads to far better durability, reduced water infiltration, and boosted resistance to chemicals and weathering. Home builders count on it for bridges, passages, and aquatic frameworks where long life and security matter a lot of.

Enhancing High Quality in Paints and Coatings

In paints and commercial coverings, this white powder acts as a thickening and anti-settling agent. It helps keep pigments uniformly spread out and prevents clumping throughout storage. The outcome is a smoother application, constant surface, and much longer shelf life. It also includes scrape resistance and boosts how well the layer adheres to surface areas.

Improving Rubber and Plastics

Producers add Silicon Dioxide 200 to rubber substances to enhance tensile stamina and tear resistance. In plastics, it enhances stiffness without adding much weight. This makes end products much more reputable and ideal for demanding usages like vehicle components or electrical insulation.

Supporting Adhesives and Sealants

This silica powder manages flow and prevents drooping in adhesives and sealers. It provides the best uniformity for simple handling while keeping strong bonding power. Whether made use of in construction or home repairs, these items carry out better with fume silica included.

Usage in Specialty Applications

Beyond common industrial uses, Silicon Dioxide 200 Fume Silica appears in cosmetics, preservative, and pharmaceuticals– always in its pure, food-grade kind. Below, it works as a free-flow agent or stabilizer, making certain powders remain completely dry and mix uniformly. Its ultrafine bit dimension and high pureness make it secure and efficient for sensitive applications.

5 FAQs of Silicon Dioxide 200 Fume Silica White Powder Sio2

Frequently Asked Questions About Silicon Dioxide 200 Fume Silica White Powder (SiO₂)

What is Silicon Dioxide 200 Fume Silica?

Silicon Dioxide 200 Fume Silica is a very fine white powder made from high-purity silica. It is produced by burning silicon in a flame, which creates tiny particles of amorphous SiO₂. This material has a large surface area and strong thickening power. People use it in many industries because it improves texture, stability, and performance.

Is this product safe to handle?

Yes, but you must follow basic safety rules. The powder is not toxic, but breathing in fine dust over time may irritate your lungs. Always wear a mask, gloves, and eye protection when handling it. Work in a well-ventilated area. Keep the container closed when you are not using it.

What are the main uses of this silica powder?

This fume silica works as a thickener, anti-caking agent, and reinforcing filler. You will find it in paints, adhesives, sealants, cosmetics, and food-grade products. It helps stop powders from clumping. It also makes liquids thicker without changing their color or smell.

How should I store Silicon Dioxide 200?

Store it in a dry, cool place. Keep the bag or container sealed tightly after each use. Moisture can cause the powder to form lumps. Do not store it near strong acids or bases. Use clean, dry tools when scooping the powder to avoid contamination.

Can I use this in food or pharmaceutical products?

Only if the product meets food-grade or pharmaceutical standards. Not all fume silica is approved for these uses. Check the certificate of analysis and make sure it follows local regulations like FDA or EU guidelines. If you are unsure, ask the supplier before using it in consumable products.
