Vapor Deposited Aluminum Polyimide Aerogel Thermal Protection Film AZ-TPS VDA PI 100
AZ-TPS VDA PI 100 is a 240 μm (9.5 mil) thermal protection film built around a 165 μm (6.5 mil) AeroZero® polyimide aerogel core laminated between 25.4 μm (1 mil) polyimide face films, with one face vapor-deposited with a 1000 Å reflective aluminum (VDA) layer. The opposite face carries a 25.4 μm (1 mil) silicone pressure-sensitive adhesive with a peel-away release liner for direct bonding to metal, glass, and polymer substrates. The construction delivers 0.94 IR reflectivity, 0.046 W/m·K thermal conductivity, and a UL94 VTM-0 flame rating for thermal barrier applications.

AZ-TPS VDA PI 100 is a laminated thermal protection film built around an AeroZero® polyimide aerogel core, positioning it within Blueshift Materials’ AZ-TPS thermal protection film family. The aerogel core is sandwiched between two polyimide face films, with one outer surface treated with a vapor-deposited aluminum (VDA) layer to deliver high infrared reflectivity for radiant heat management. The opposing face is factory-coated with a silicone pressure-sensitive adhesive under a peel-away release liner, allowing the film to be bonded directly to stainless steel, aluminum, glass, and polymer substrates — including polyimides, polyether ketones, polyurethanes, and polyesters — without a secondary adhesive system. This combination of low thermal conductivity, high IR reflectivity, and an integral bonding layer allows the film to function as a lightweight, ultra-thin thermal protection system (TPS) on complex, contoured parts.
Beyond its thermal performance, AZ-TPS VDA PI 100 is flame retardant, carrying a UL94 VTM-0 rating, and exhibits a Dielectric Constant of 1.92 and Dissipation Factor of 0.012 at 10 GHz, indicating suitability near RF and microwave circuitry. The film retains dimensional and thermal stability up to a glass transition temperature of 305°C (580°F) and begins measurable decomposition (10 wt% loss) at 410°C (770°F). Its flexible, thin-gauge construction supports application onto complex part geometries with a permanent, easy-to-apply bond. Compliant with UL94 VTM0.
What differentiates AZ-TPS VDA PI 100 from other thermal protection film constructions?
AZ-TPS VDA PI 100 pairs an AeroZero® polyimide aerogel core with a vapor-deposited aluminum (VDA) face, achieving 0.94 IR reflectivity and 0.046 W/m·K thermal conductivity in a total construction just 240 μm (9.5 mil) thick. The integral silicone PSA layer and peel-away liner on the opposite face allow the film to be bonded directly to stainless steel, aluminum, glass, and polymer substrates without a separate adhesive system, combining radiant and conductive thermal management with ready-to-apply installation.
Why do thermal conductivity and IR reflectivity matter in material selection for AZ-TPS VDA PI 100?
As a thermal protection film, AZ-TPS VDA PI 100's function depends on limiting both conductive and radiant heat transfer. The 0.046 W/m·K thermal conductivity of the aerogel core minimizes heat conducted through the film, while the 0.94 IR reflectivity (0.06 emissivity) of the VDA-PI surface reflects radiant heat away from the protected structure. Together these properties determine how effectively the film shields aerospace, defense, and electronics substrates from thermal loads.
What is the thermal stability range for AZ-TPS VDA PI 100?
The TDS lists a glass transition temperature (AZ Tg, DMA) of 305°C (580°F) and a decomposition temperature (10 wt% loss, TGA) of 410°C (770°F). No separate continuous-use service temperature range is specified on the manufacturer's TDS.
Is AZ-TPS VDA PI 100 suitable for flame-rated aerospace and defense environments?
Yes. AZ-TPS VDA PI 100 carries a UL94 VTM-0 flammability rating (UL94 VTM0 test method), supporting use in aerospace, defense, and electronics thermal protection applications where flame-retardant performance is required.
How should AZ-TPS VDA PI 100 be specified?
Specify grade (AZ-TPS VDA PI 100), thickness, adhesive/liner type, bonding substrate, compliance requirements, dimensional tolerances, and finished format.
