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.

The material is hydrophilic and distributes well in polar systems. It develops stable three-dimensional networks in liquids, which helps control flow and prevent sedimentation.

Common Applications

Fumed Silica A200 functions well in several industrial products. It is frequently included in adhesives and sealants to boost thickness and droop resistance. In layers and paints, it quits pigments from resolving and boosts scrape resistance. The item additionally strengthens silicone rubber and boosts the efficiency of printing inks, greases, and unsaturated polyester materials. Its great bit size and high area make it ideal for demanding formulations that require constant structure and stability.

Handling and Storage space

Shop Fumed Silica A200 in a dry, amazing location. Maintain containers sealed when not in use to prevent wetness absorption. Usage basic industrial health methods throughout handling. Wear safety handwear covers and eye security. Prevent creating dust clouds. If breathed in or contacted with skin, follow standard first-aid procedures. Always refer to the Safety and security Data Sheet (SDS) prior to usage.

Applications of Industrial Grade Fumed Silica A200

Applications of Industrial Grade Fumed Silica A200

Enlarging and Anti-Settling Agent

Fumed Silica A200 works well as a thickener in lots of commercial liquids. It quits strong fragments from sinking to the bottom. This keeps paints, finishings, and adhesives secure over time. Customers get regular efficiency without shaking or remixing before usage.

Rheology Control in Sealants and Adhesives

In sealers and adhesives, A200 offers much better control over flow. It helps the product keep where it is used. The item does not leak or sag on upright surfaces. This makes application much easier and results a lot more trustworthy.

Support in Silicone Rubbers

Fumed Silica A200 strengthens silicone rubber substances. It improves tear resistance and tensile strength. These rubbers are made use of in vehicle parts, medical gadgets, and kitchenware. The included silica makes certain resilient toughness under anxiety.

Free-Flow Representative for Powders

Dry powders frequently clump together in storage space. Including a percentage of A200 stops this. It layers each bit and lowers dampness absorption. Therefore, powders stream easily during manufacturing and packaging.

Matting Agent in Coatings

For layers that need a non-glossy coating, Fumed Silica A200 creates a consistent matte appearance. It scatters light equally across the surface. This impact is common in furnishings coatings, building paints, and printing inks.

Stable Efficiency Throughout Conditions

A200 remains reliable in a wide range of temperatures and humidity degrees. It does not lose function when mixed with other chemicals. Industries count on it due to the fact that it provides consistent outcomes batch after set. Its pureness and consistent bit dimension make it a trusted choice for requiring applications.

5 FAQs of Industrial Grade Fumed Silica A200

Frequently Asked Questions About Industrial Grade Fumed Silica A200

What is Fumed Silica A200?

Fumed Silica A200 is a high-purity, synthetic amorphous silica. It is made through flame hydrolysis of silicon tetrachloride. This process creates very fine particles with a large surface area. The material appears as a fluffy white powder. It is widely used in industrial applications for thickening, reinforcing, and anti-settling purposes.

Why choose A200 over other grades?

A200 offers consistent quality and performance. Its specific surface area is around 200 m²/g, which gives it strong thickening power. It works well in many systems, including coatings, adhesives, and sealants. The product also has excellent flow properties and disperses easily when mixed correctly.

How should A200 be handled safely?

Always wear protective gear like gloves, goggles, and a dust mask. A200 is not toxic, but inhaling fine dust may irritate the lungs. Work in a well-ventilated area. Keep the container closed when not in use to avoid moisture absorption. Store it in a dry place at room temperature.

Can A200 be used in food or medical products?

No. Industrial Grade Fumed Silica A200 is not approved for food, pharmaceutical, or cosmetic use. It is meant only for industrial applications. If you need silica for those sensitive areas, look for grades that meet relevant safety and regulatory standards.

How do I mix A200 into liquids without clumping?

Add A200 slowly while stirring the liquid at high speed. Use a high-shear mixer if possible. This helps break up agglomerates and ensures even dispersion. Pre-mixing with a solvent or part of the base liquid can also reduce clumping. Avoid adding all the powder at once—it may form hard lumps that are hard to dissolve later.
