AeroZero® Polyimide Aerogel Film with Silicone Pressure-Sensitive Adhesive AZ-TPS 100
AZ-TPS 100 is an ultra-thin, adhesive-backed thermal protection film built from a 165 micron (6.5 mil) AeroZero® polyimide aerogel layer laminated to a 25.4 micron (1 mil) silicone pressure-sensitive adhesive, yielding a total construction thickness of 190 µm (7.5 mil) and a thermal conductivity of 0.038 W/m·K at 25°C. The film retains a glass transition temperature of 305°C (580°F), with thermal decomposition (10% weight loss) not occurring until 410°C (770°F), and carries a UL94 VTM-0 flame retardant rating. Its silicone adhesive provides permanent bonding to stainless steel, aluminum, glass, carbon fiber, and polymer substrates.

AZ-TPS 100 is an ultra-thin thermal protection system (TPS) built on Blueshift Materials’ AeroZero® polyimide aerogel film technology, combined with a silicone pressure-sensitive adhesive layer for direct, permanent application to a substrate without additional fasteners or bonding media. The construction is designed to deliver a low-thermal-conductivity barrier layer in an exceptionally thin, flexible format suitable for wrapping or laminating onto complex, curved, or space-constrained part geometries in aerospace, defense, and electronic assemblies.
Beyond its thermal performance, the film demonstrates high thermal stability, retaining a glass transition temperature of 305°C (580°F) and resisting thermal decomposition (10% weight loss) up to 410°C (770°F), while carrying a UL94 VTM-0 flame retardant rating for use in applications where flammability performance is a design requirement. The adhesive layer is protected by a release liner that is removed at the point of application, and the cured bond is rated for permanent adhesion to stainless steel, aluminum, glass, carbon fiber, and polymer substrates. Compliant with UL94 VTM-0.
What differentiates AZ-TPS 100 from conventional thermal insulation films and tapes?
AZ-TPS 100 pairs an ultra-thin 190 µm (7.5 mil) total construction with an extremely low thermal conductivity of 0.038 W/m·K, a glass transition temperature of 305°C (580°F), and a UL94 VTM-0 flame retardant rating. This combination allows the film to deliver a flame-rated thermal barrier at a fraction of the thickness and weight of conventional insulation layers, while its silicone PSA enables direct, permanent bonding without secondary fasteners.
Why does thermal conductivity matter in material selection for AZ-TPS 100?
As a thermal protection system, AZ-TPS 100's function depends on limiting heat transfer through an ultra-thin cross-section. Its 0.038 W/m·K thermal conductivity is the primary property that determines how effectively the film insulates a substrate or component within the tight thickness and weight budgets typical of aerospace, defense, and electronic assemblies.
What is the service temperature range for AZ-TPS 100?
AZ-TPS 100 retains a glass transition temperature (AZ Tg, DMA) of 305°C (580°F), with thermal decomposition (10% weight loss, TGA) not occurring until 410°C (770°F).
Is AZ-TPS 100 suitable for flame-rated aerospace and defense environments?
Yes. AZ-TPS 100 carries a UL94 VTM-0 flame retardant rating, the only compliance standard specified on the manufacturer's TDS.
How should AZ-TPS 100 be specified?
Specify grade (AZ-TPS 100), thickness, adhesive type (silicone PSA), liner type, substrate compatibility, compliance requirements, and dimensional tolerances.
