Manufacturer
Aspen Aerogels ® is the world's leading manufacturer of airgel blankets and has pioneered the development of this technology in the industrial marketplace since 2001. The Pyrogel® and Cryogel Z® insulation is now widely accepted and adopted as the benchmark standard for airgel technology. Aspen's aerogel insulation is up to five times more effective than traditional insulation materials. The materials offer space-saving, easy-to-use solutions over a wide temperature range, making them the most efficient industrial insulation on the market.

About the material
The aerogel part of our high performance insulation blankets is comprised of synthetic amorphous silica (SAS). The other major ingredient in our products is a non-woven, needled batting comprised of either E-glass fibers or a blend of polyester (PET) fibers and E-glass fibers. Synthetic amorphous silica has been produced for more than 100 years for a variety of uses (adsorbents, fillers, anti-caking agents) and consumer products (toothpaste, cosmetics, food, animal feed).
The US EPA recently listed synthetic amorphous silica as a chemical on the Safer Chemical Ingredient List, part of the Safer Choice program. The Safer Chemical Ingredients List (SCIL) is a list of chemical ingredients that the Safer Choice Program has evaluated and determined to be safer than traditional chemical ingredients.
Material development
Aerogels have been in existence for more than 80 years. Invented in 1931 by Dr. Samuel Kistler at the College of the Pacific in California, silica aerogel is a lightweight solid derived from gel in which the liquid component of the gel has been replaced with gas. When the liquid is removed, what remains is “puffed-up sand," with up to 99% porosity. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as a thermal insulator. Aerogels also have value in emerging applications such as energy storage, filtration and carbon capture.
Safety instructions
Synthetic amorphous silica is oleophilic, so it readily absorbs the oils from your skin. This characteristic is why synthetic amorphous silica is used in cosmetics as an anti-sheen agent. For worker comfort when working with Pyrogel®, Cryogel® or Spaceloft®aerogel blanket insulation, we recommend safety eyewear, work gloves, long sleeves, and long-legged work clothes. Respiratory protection is recommended if dust exposures exceed occupational exposure limits. Aerogel dust is easily washed from the skin and clothing using soap and water.
Characteristics
The solids in silica aerogels have low conductivity and consist of very small, three-dimensional, intertwined clusters that make up only 3 % of the volume. The conductivity through the solid is therefore very low. The remaining 97 % of the volume of the aerogels consist of air in extremely small nanopores. The air has little room to move, which hinders both convection and gas phase conduction. These properties make aerogels the lowest density solid and the most effective thermal insulator in the world. After many decades as a laboratory curiosity, Aspen Airogels has successfully developed a technically and economically feasible form of airgel for industrial and building insulation applications.
