Overview of silica aerogel powders and particles

silica aerogel powders and particles can meet the most demanding thermal insulation challenges across various industries. Our portfolio includes aerogel powder, aerogel thermal insulation coating, and aerogel insulation felts in various specifications, each engineered for superior performance.

Characteristics of silica aerogel powders and particles

Aerogel Powder is the fundamental form of this revolutionary material, characterized by its extremely low density and high surface area. It serves as a critical additive for enhancing thermal properties in composites, plastics, coatings, and functional materials, bringing nano-scale insulation power to your formulations.

The Aerogel Thermal Insulation Coating integrates our proprietary powder into a robust, easy-to-apply solution. This coating provides exceptional thermal resistance, weatherproofing, and corrosion protection for pipes, tanks, and industrial structures. It is ideal for complex geometries where traditional insulation is impractical, sealing heat loss effectively.

Our Aerogel Insulation Felts are flexible, durable blankets available in various thicknesses, densities, and dimensions to suit diverse applications. Combining the phenomenal insulating power of aerogel with a practical, roll-out format, they are perfect for high-temperature industrial piping, HVAC systems, building envelopes, and more. They offer maximum thermal efficiency with minimal space requirements.

Spec of Silica Aerogel Powders and Particles

Physical Kind

Silica aerogel powders appear as fine, free-flowing fragments. The product is white to off-white in color. It has a soft, cosy structure comparable to baby powder. Bit dimension commonly varies from 1 to 100 micrometers. Mass thickness falls in between 30 and 150 kg/m TWO, depending on the quality.

Thermal Qualities

Silica aerogel offers exceptional thermal insulation. Its thermal conductivity is among the lowest of any type of solid material– generally between 0.012 and 0.020 W/(m · K) at room temperature level. This efficiency continues to be steady throughout a wide temperature level range, from -200 ° C to +650 ° C. The product does not melt or deteriorate under normal operating problems.

Chemical Structure

The main element is amorphous silica (SiO ₂), making up over 90% of the item. Trace amounts of dampness might exist, generally less than 5% by weight. The material is non-toxic and chemically inert under conventional ecological problems. It withstands most acids however can react with strong alkalis and hydrofluoric acid.

Pore Structure

Silica aerogel includes an extremely porous nanostructure. Porosity exceeds 90%, with ordinary pore diameters around 10 to 20 nanometers. This ultra-fine network produces a large interior area– commonly 500 to 800 m TWO/ g– as gauged by wager analysis. The framework catches air successfully, which is key to its insulating capability.

Handling and Storage space

Store in a dry, sealed container far from wetness and direct sunshine. Prevent extended skin contact; usage gloves and eye security during handling. The powder can create dirt, so work in a well-ventilated area or usage neighborhood exhaust ventilation. Avoid open flames, though the material itself is non-flammable.

Applications of silica aerogel powders and particles

Applications of Silica Aerogel Powders and Particles

Thermal Insulation

Silica aerogel powders are recognized for their impressive thermal insulation. They trap air in a network of small pores, which decreases warmth transfer. This makes them excellent for usage in structure materials like insulating plasters, finishes, and panels. They help keep homes warm in wintertime and cool in summer season while utilizing much less power.

Oil Spill Cleanup

These bits can soak up large quantities of oil– sometimes more than 100 times their very own weight. They ward off water however draw in oil, so they work well in cleaning up spills ashore or water. After use, the oil-soaked aerogel can typically be pressed or burnt, permitting reuse sometimes.

Additive in Coatings and Paints

When mixed right into paints or industrial coatings, silica aerogel bits include insulation without transforming just how the covering looks or uses. The final surface stays smooth and slim but gains better warm resistance. This works for pipelines, tank, and even exterior structures subjected to temperature level swings.

Individual Protective Devices

Manufacturers blend silica aerogel powders right into fabrics used for firefighter gear, military uniforms, and wintertime apparel. The material adds warmth without including mass. Customers stay safeguarded from severe chilly or warmth while relocating easily.

Specialty Product packaging

In high-value shipping– like drugs or electronic devices– silica aerogel particles help keep stable temperatures inside bundles. They fit into little areas and give trusted thermal buffering throughout transport, particularly where refrigeration isn’t possible.

Cosmetics and Personal Treatment

Some skin care and make-up products utilize great silica aerogel particles for their light structure and oil-absorbing capacity. They offer a matte finish, decrease shine, and boost how products really feel on the skin without blocking pores.

5 FAQs of silica aerogel powders and particles

Frequently Asked Questions About Silica Aerogel Powders and Particles

What is silica aerogel powder?

Silica aerogel powder is a very light material made mostly of air. It has a porous structure that traps air inside. This gives it excellent insulation properties. People often call it “frozen smoke” because it looks cloudy but feels dry.

Why use silica aerogel in insulation?

Silica aerogel is one of the best insulators known. It slows down heat transfer better than most materials. You can add it to paints, coatings, or building materials. This helps keep heat in during winter and out during summer. It works well even in thin layers.

Is silica aerogel safe to handle?

Yes, but you should take basic safety steps. Wear gloves and a mask when working with fine powders. The particles are not toxic, but breathing in any fine dust may irritate your lungs. Store it in a dry place away from moisture.

How do you mix silica aerogel into other products?

You can blend the powder into liquids like paints, resins, or sealants. Stir slowly to avoid breaking the fragile particles. Use low-shear mixing tools. Follow the supplier’s instructions for the right amount to add. Too much may affect the final product’s strength or texture.

Does moisture affect silica aerogel performance?

Yes, moisture can reduce its insulating ability. Water fills the tiny air pockets and lets heat move more easily. That’s why many products use hydrophobic (water-repelling) silica aerogel. Always check if the version you buy resists water, especially for outdoor use.
