AeroZero® Film

AeroZero® is a polyimide aerogel film manufactured in a roll-to-roll process. AeroZero is a mechanically durable insulating film that is tolerant to very high heat and cryogenic temperatures.  Comprised of 80-85% air an ultra-low density (0.27g/cm3), AeroZero is nicknamed Structured Air. The film thus has high porosity, ultra-low dielectric loss properties, and extremely low thermal conductivity.   Being a polyimide, AeroZero retains many key properties such as wide operating temperature range (-200 C to +260 C), inherent flame retardancy, and chemically resistant.

The Benefits of Choosing AeroZero®

Thermal Control

Aerogels have long been prized as superior insulators, second only to vacuum. AeroZero® continues that tradition offering low thermal conductivity.


With a density of 0.27 g/cm3 AeroZero® is approximately 5 times less dense than traditional polyimides. As various industries are lightweighting their products, AeroZero will become a powerful asset for those looking to shed mass.

Tough & Flexible

AeroZero® uses the durability of polymers to provide remarkable compression resistance and tensile strength. As a stock shape, it has the mechanical strength to be a composite fore material. As a film, it has the flexibility to adhere to tight curvatures.

RF Transparency

With an ultra-low dielectric constant (Dk) of approximately 1.45 and an ultra-low loss tangent of approximately 0.004 over 1-10 GHz, AeroZero® film alters. With performance characteristics of wide bandwidth and high gain combined with material properties such as low density, environmental stability, and toughness superior to the current state of practice, new electronic concepts are enabled.

Environmentally Tolerant

Able to withstand a significant range of extremes from high temperatures to cryogenic conditions, AeroZero® can improve the construction and performance of many design types.
