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.

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!
