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.

Classic Silica 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. Please note this product currently has a six-week lead time.

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.

Please note this product currently has a six-week lead time.

For serious applications demanding silica aerogel, Classic Silica 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 aerogel 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 Iannis Michalous are a unique and beautiful visual creation born from the unusual properties of silica aerogel. Contained in each Bottled Sky is a “cloud”, unique in form and which can never be repeated. 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. A special gift for that special geek in your life!

Thermal Wrap™ aerogel blankets from Cabot provide the superinsulating properties of silica aerogel in a flexible form that is virtually dust-free!  Excellent for engineering projects, ambient and sub-ambient insulating applications, and more. Easy to cut and handle.  Useful as a translucent fabric for daylighting and acoustic damping in buildings.  Thermal conductivity is ~23 mW m^-1 K^-1 at room temperature. A great alternative to Spaceloft^® or Cryogel^® for dust-sensitive applications.  For large quantity requests, please contact us.

Lumira^® Aerogel granules 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.

Due to a temporary manufacturing shortage, this item is currently out of stock.  In the interim, we recommend substituting Cryogel^® 201, which has similar performance characteristics.

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.

The world’s most advanced flexible insulation, Aspen Aerogels’ Pyrogel^® XT is a flexible aerogel composite blanket designed for high-temperature applications (up to 650°C/1200°F), with thermal performance two to eight times greater than other high-temperature insulating materials. Great for blowtorch experiments! Download the MSDS.

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

Aspen Aerogels’ Cryogel^® 201 is a flexible aerogel composite blanket designed for insulating cold temperature environments ranging from cryogenic to ambient. With a thermal conductivity of 14 mW m^-1 K^-1 at room temperature, Cryogel insulates even better at lower temperatures with a thermal conductivity of only 10 mW m^-1 K^-1 at -330°F/-200°C!  Lighter than Spaceloft but dustier.  Maximum temperature is 390°F/200°C, density is only 0.13 g cm^-3 (2.13 oz/60 g per square foot).  This product does not have a reflective barrier film like Cryogel Z.
