Classic Silica aerogel is just that – the same ethereal blue material NASA has used on the Mars rovers and the Stardust mission! Extremely hard-to-find transparent monolithic form. Great for gifts, science projects, and display. Density is ~0.095 g/cm³, meaning these aerogels are an incredible 96% air by volume!  Hydrophilic surface chemistry.

Airloy™ X100 series materials from Aerogel Technologies are the world’s first commercially-available mechanically robust aerogels with the strength to stand up to real-world applications.  Airloy X100 comes in densities up to fifteen times lighter than plastics (about the same density as our Classic Silica aerogels) yet is about 100x stronger in compression than classic aerogels and without the fragility of classic aerogels.  Impervious to contact with moisture and liquid water.  Dust-free.  Provides 10-1000x better acoustic damping than traditional engineering materials over most audible frequencies.  Easy to machine and adhere.  Thermally superinsulating with a conductivity between classic silica aerogels and Styrofoam^®.  Maximum operating temperature is ~180°C.

Airloys are ordered by density.  Properties such as strength and stiffness increase with increasing density, while thermal conductivity decreases with decreasing density.  Airloy densities are indicated by:

• “L” 100 ± 20 mg/cc
• “M” 200 ± 20 mg/cc
• “H” 300 ± 20 mg/cc

Additional sizes, operating temperatures, and densities are available by request.

Carbon Aerogel monoliths from Aerogel Technologies are electrically- conductive aerogels composed of amorphous carbon.  Useful for applications where both a high surface area and electrical conductivity are desirable.  With a mean pore size of ~25 nm, these aerogels provide plenty of pore volume for inclusion of active materials and for facilitating mass transport.  Ideal for use as electrodes in supercapacitors and ultracapacitors, batteries, and desalination filters.  Excellent supports for high-temperature heterogeneous catalysis.  BET surface area is approximately 700 m² g^-1.  Density is ~0.2 g/cc.

Classic Silica Aerogel Blocks have a square cross-section, flat surfaces, and sharp edges for applications where round shapes just won’t do.  Great for experiments involving optics and projects where parts need to be mounted or tiled.  Top side of the block may be slightly curved.  Density is ~0.095 g/cm³.  Hydrophilic surface chemistry.

The famous blue aerogel, now in cylinder form!  Classic Silica Aerogel Cylinders are an ideal shape for numerous applications including dessication and molecular adsorption, strength testing, optics, miniature structures, and more.  Density is ~0.095 g/cm³.  Hydrophilic surface chemistry.

Hydrophobic Silica aerogels are specially formulated to repel water and to not absorb moisture from the air.  Where Classic Silica tends to shrink and cloud in humid environments, Hydrophobic Silica retains its transparency and integrity.  Floats on water without damage!  Excellent for applications involving absorption of hydrophobic substances such as oil.

For serious applications demanding silica aerogel, Classic Silica Aerogel Tiles fit the bill.  About the size of a playing card, these tiles are big enough to shield against open flames.  Useful for advanced optics, particle detection, and adsorption applications.  Great for  demonstrations and extreme engineering projects!  Density is 0.095 g/cm³.  Hydrophilic surface chemistry.

Organic RF Polymer aerogels are made of resorcinol-formaldehyde polymer – the same material found in Bakelite and other phenolic resins. Suitable for conversion to electrically conductive carbon aerogels through heat treatment under inert atmosphere. Ideal for research in catalysis, batteries, fuel cells, super-/ultracapacitors, desalination filters, and more. Thermal insulating characteristics similar to or better than Classic Silica at ambient conditions. Great for applications where an electrically insulating organic material is desirable. Color is a slightly translucent deep red. Available in shaped form exclusively through BuyAerogel.com.
Density is ~0.14 g/cm³, which is ~90% air by volume.

Bottled Skies by Ioannis Michalou(di)s are a unique and beautiful visual creation born from the unusual properties of silica aerogel. Bottled Skies are blue in front of a black background, virtually invisible in front of a white background, and cast a shadow with a golden hue reminiscent of the sun’s rays.  Medium Bottled Sky consists of pure silica aerogel cast into a signed, individually numbered bottle accompanied by a combination red laser/white LED keychain to experience the striking optical properties of aerogel firsthand.  Large Bottled Sky consists of pure silica aerogel embedded with a “cloud”, unique in form and which can never be repeated. A special gift for that special geek in your life!

Lumira^® Aerogel particles from Cabot are hydrophobic (water-repelling) millimeter-sized particles of silica aerogel produced through subcritical drying. Used in a variety of industrial applications including subsea pipe insulation and daylighting. Use it as an inexpensive way to experience some classic “blue” aerogel or as fill to make your own translucent superinsulating barrier.  Download the United States MSDS or the European Union MSDS.

Aspen Aerogels’ Spaceloft^® is a flexible aerogel composite blanket designed for insulating buildings and apparel. With a thermal conductivity of 14 mW m^-1 K^-1, Spaceloft is approximately two and half times better insulating than Styrofoam^®. Great for home insulation, winter clothing, science projects, and any application where thermal insulation is needed and space is at a premium. Maximum temperature is 390°F/200°C, density is 0.15 g cm^-3 (2.45 oz/69 g per square foot). Download the MSDS here.

Note: Product is dusty; gloves, eye protection, and dust mask recommended for handling.
