AeroZero® Polyimide Aerogel Film with Double-Sided Silicone Pressure-Sensitive Adhesive AZ-TPS 101
AZ-TPS 101 is a 216 micron (8.5 mil) thermal protection film consisting of a 165 micron (6.5 mil) AeroZero® polyimide aerogel core bonded between two 25.4 micron (1 mil) silicone pressure-sensitive adhesive layers, with a density of 0.50 g/cm³. The film provides a thermal conductivity of 0.040 W/m·K at 25°C, a decomposition temperature of 380°C (716°F), and a UL94 VTM-0 flammability rating. Adhesive strength exceeds 300 N/m (1.7 Lbf/in) to aluminum foil after a 3-day room-temperature dwell, supporting permanent, flexible bonding to metal, glass, carbon fiber, and polymer substrates.

AZ-TPS 101 is a thin, flexible thermal protection film construction built around a polyimide aerogel core from the AeroZero® product line, factory-laminated with silicone pressure-sensitive adhesive on both faces for direct application to a substrate. The construction is intended to add thermal barrier performance to aerospace, defense, and electronic components without the bulk of traditional insulation systems, delivering a thermal conductivity of 0.040 W/m·K at 25°C in a total construction thickness of 216 microns (8.5 mil) and a density of 0.50 g/cm³.
The aerogel core maintains a glass transition temperature of 305°C (580°F) and resists decomposition to 380°C (716°F) (10 wt% loss, TGA), while the double-sided silicone adhesive system provides adhesive strength greater than 300 N/m (1.7 Lbf/in) to aluminum foil following a 3-day room-temperature dwell, enabling permanent, flexible bonds to metal, glass, carbon fiber, and polymer substrates. The film’s flexibility allows it to be wrapped onto complex, contoured part geometries during application, and it carries a UL94 VTM-0 flammability rating. Compliant with UL94 VTM-0.
What differentiates AZ-TPS 101 from other thermal protection film constructions?
AZ-TPS 101 combines an ultra-thin, 216 micron (8.5 mil) total construction with a low thermal conductivity of 0.040 W/m·K and a double-sided silicone pressure-sensitive adhesive system, allowing it to be applied directly and permanently to metal, glass, carbon fiber, and polymer substrates without a separate bonding step. Its flexibility supports wrapping onto complex, contoured part geometries while retaining a UL94 VTM-0 flammability rating.
Why does thermal conductivity matter for AZ-TPS 101's thermal protection application?
Thermal conductivity determines how effectively the film limits heat transfer across a bonded substrate in a given thickness. AZ-TPS 101's 0.040 W/m·K value (25°C) allows it to function as a thermal barrier in aerospace, defense, and electronic applications while adding minimal thickness or weight to the finished part.
What is the temperature range for AZ-TPS 101?
AZ-TPS 101 maintains a glass transition temperature (AZ Tg, DMA) of 305°C (580°F) and begins decomposition (10 wt% loss, TGA) at 380°C (716°F).
Is AZ-TPS 101 suitable for flame-rated environments?
Yes. AZ-TPS 101 is UL94 VTM-0 rated.
How should AZ-TPS 101 be specified?
Specify grade (AZ-TPS 101), thickness, adhesive type, compliance requirements, dimensional tolerances, and finished format.
