Airloy® Product Selection Guide

Airloys are a platform technology with uses in many markets. Below is a product selection guide based on product feature for different applications.

Transparency, Light Transmissiveness, Classic Aerogel Look with Improved Durability

Recommended Product: Airloy X56-MH

  • Airloy X56 is an optically transparent, low thermal conductivity, machinable, and mechanically durable aerogel. Airloy X56 enables image preservation through 1-cm thick parts with over 80% light transmission, however unlike traditional aerogels is durable and machinable.

Highest Strength and Stiffness at Low Densities

Recommended Products: Airloy X103-M, Airloy X116-L, Airloy T116-L, and Airloy X126-L

  • Airloys X103, X116, T116, and X126 provide the best strength and stiffness at densities of 0.09-0.2 g/cc. Airloy X103-M is a good optimization of high strength and stiffness at 0.2 g/cc. Airloy X116-L and T116-L provide good strength and stiffness at densities as low as 0.09 g/cc while providing thermal conductivities as low as 22 mW/m-K. Airloy X126-L provides the highest stiffness at the lowest density, with high thermal conductivity of 48 mW/m-K for applications where heat trapping is undesirable.

Homogenous at Macroscale and Microscale

Recommended Products: All Airloys

  • Airloy Ultramaterials are effectively homogenous at the macro- and microscales thanks to their high definition pore structure. Unlike foams, Airloys can be machined and made into thin films without pores interfering with part continuity.

Lowest Density, Highest Weight Savings, Highest Buoyancy

Recommended Products: Airloy X116-XL

  • The lowest density Airloy product is Airloy X116-XL with a density of 0.06 g/cc. However, when choosing an Airloy, other properties such as strength, stiffness, thermal conductivity, sound transmission loss, hydrophobicity, and temperature stability should be taken into consideration. Different Airloy materials with higher densities may provide better weight savings when these other properties are taken into consideration.

Machinability, Adhesive Compatability, and Compositing

Recommended Products: All Airloys

  • Airloy Ultramaterials are formulated for engineering applications and can all be machined, adhered, and composited. Airloys X103 and X116 are particularly easy to use for these applications. See our machining guidelines for more information.

Best Thermal Insulation Performance, Highest R-Value, Lowest Thermal Conductivity

Recommended Products: Airloy X114-M, Airloy X116-L, Airloy T116-L, and Airloy X56-MH

  • Airloy Ultramaterials have excellent thermal insulating performance comparable to or better than materials such as expanded polystyrene, polyurethane foam, and mineral wool with many additional benefits. For the best thermal insulation, Airloy X114-M offers thermal conductivities as low as 20 mW/m-K with thermal stability up to 400°C at densities as low as 0.2 g/cc. Airloy X116-L provides thermal conductivities as low as 22 mW/m-K and hydrophobicity at densities as low as 0.09 g/cc. Airloy T116-L is similar to X116-L with excellent dimensional stability up to 400°C. Airloy X56-MH provides thermal conductivities as low as 24 mW/m-K at densities of 0.3 g/cc and transparency.

Highest Temperature Performance and Dimensional Stability

Recommended Products: Airloy X114-H and Airloy T116-L

  • For temperature performance up to 400°C, Airloys X114-H and T116-L provided unparalleled performance. Additionally, these materials do not burn, smoke, or drip when exposed to flame and instead carbonize at high temperatures. Airloy X114-H provides the highest strength and stiffness at a density of 0.4 g/cc, while T116-L provides great strength and stiffness at a density as low as 0.09 g/cc.

High Strength and Stiffness and Medium Temperature Performance up to 150°C

Recommended Products: Airloy X134-MH

  • For medium temperature applications, Airloy X134-MH provides great strength and stiffness, good thermal insulating properties comparable to expanded polystyrene, and operating temperatures up to 150°C.

Best Soundproofing, Highest Sound Transmission Loss

Recommended Products: All Airloy products, higher densities

  • Thanks to their high stiffness at low densities at high definition pore structure, Airloy Ultramaterials offer unparalleled sound transmission loss per thickness over other materials. Airloy X103-XH, for example, provides up to 50 dB/cm sound transmission loss where acoustics foams provide only about 5. Higher density Airloy materials provide higher sound transmission loss, ranging from about 20 dB/cm to 50 dB/cm from 0.1 g/cc to 0.55 g/cc.

Nonflammability for Aviation and Automotive Applications

Recommended Products: Airloy X114-M, Airloy X114-H, Airloy X116-L, Airloy T116-L, Airloy X126-L

  • For applications in aviation and automotive, Airloy X110 and X120 series materials provide excellent nonflammability properties. Airloy X110 and X120 series materials don’t burn, smoke, or drip when exposed to flame while providing excellent strength and stiffness at low densities, water resistance, high sound transmission loss, and low thermal conductivity in the same material envelope. Airloy X116-L and Airloy XT116-L are particularly optimized for aviation applications, where Airloy T116-L offers improved dimensional stability at high temperatures.

Hydrophobicity, Water Resistance, and Moisture Resistance

Recommended Products: Airloy X116-L and Airloy T116-L

  • While all Airloy Ultramaterials offer water resistance, Airloy X116-L and Airloy T116-L provide hydrophobicity with contact angles greater than 140°.


Recommended Products: Airloy X103-L, Airloy X103-M, Airloy X103-H, and Airloy X103-XH

  • For lightweight materials with high strength, high stiffness, and low thermal conductivity that can be thermoformed into shape, Airloy X103 is recommended. Airloy X103 is available in densities ranging from 0.1 to 0.55 g/cc and can thermoformed into shapes by heating to 60-80°C under force.

Highest Performance Airloy—Strong, Insulating, Hydrophobic, and Nonflammable

Recommended Product: Airloy T116-L

  • For the most demanding lightweighting applications, Airloy T116-L provides high strength and stiffness and densities as low as 0.1 g/cc, thermal conductivities as low as 22 mW/m-K, hydrophobicity with contact angles up to 140°, nonflammability, and dimensional stability at high temperatures.

Lowest Cost Airloy with Good Strength, Insulating, and Water Resistance Properties

Recommended Product: Airloy X103-M

  • For applications that make use of the properties of Airloys but demand cost effectiveness, Airloy X103-M is a good option. Airloy X103-M is a high-strength and -stiffness product with a density of 0.2 g/cc, thermal conductivity of 29 mW/m-K, and is lowest cost per cubic centimeter.

Lowest Thermal Insulation Performance, Highest Thermal Conductivity

Recommended Products: Airloy X126-L

  • Airloy X126-L has a high thermal conductivity of 48 mW/m-K that permits for heat transmission in applications where trapping heat is undesirable. Airloy X126 with thermal conductivities as high as 60 mW/m-K are available. Contact us for more details.

Lowest Dielectric Constant and Loss Tangent

Recommended Products: Airloy X103-M, Airloy X116-L

  • All Airloy products have low dielectric constants and low loss tangents, however some products are particularly well-suited for applications where these values are important. Dielectric constant for Airloy products remains virtually constant over frequencies up to 30 GHz, and tends to decrease further at higher frequencies. Dielectric constant and loss tangent data are available for some products over several common frequency ranges.
