Quad-Layer AeroZero® Polyimide Aerogel Graphite Thermal Protection Film QuadZero TPS GR 400
QuadZero TPS GR 400 is a multilayer AeroZero® polyimide aerogel thermal protection film built from four 165 micron (6.5 mil) AeroZero layers bonded with silicone pressure-sensitive adhesive beneath an external 127 micron (5 mil) graphite face layer, with a total construction thickness of 838 µm (33 mil) and a density of 0.55 g/cm³. The construction delivers a thermal conductivity of 0.044 W/m·K at 25°C and remains stable to a glass transition temperature of 305°C (580°F), with decomposition onset at 425°C (797°F). The graphite face layer carries a UL94 V-0 flammability rating and complies with the 60 Second Vertical Burn test.

QuadZero TPS GR 400 is a quad-layer AeroZero® polyimide aerogel thermal protection film, combining four 165 micron AeroZero aerogel layers with an external graphite face layer and a silicone pressure-sensitive adhesive for direct bonding to a substrate. The layered construction is designed to deliver thermal insulation and heat-spreading performance in a thin, lightweight format, positioning the product for use as a thermal barrier in weight- and space-constrained thermal protection systems.
The film maintains a low thermal conductivity of 0.044 W/m·K at 25°C while retaining a total construction thickness of 838 µm (33 mil) and a density of 0.55 g/cm³. Thermal stability is supported by a glass transition temperature of 305°C (580°F) and a decomposition onset of 425°C (797°F), and the graphite face layer carries a UL94 V-0 flammability rating. Compliant with UL94 V-0 flammability rating and 60 Second Vertical Burn test.
What differentiates QuadZero TPS GR 400 from other AeroZero thermal protection film constructions?
QuadZero TPS GR 400 combines four 165 micron AeroZero polyimide aerogel layers with an external 127 micron graphite face layer and a silicone pressure-sensitive adhesive in a single 838 µm (33 mil) construction. This quad-layer build delivers a thermal conductivity of 0.044 W/m·K at 25°C together with a UL94 V-0 flammability rating, combining thermal insulation and heat-spreading performance with flame retardance in one thin, adhesive-backed film.
Why does thermal conductivity matter for QuadZero TPS GR 400 in thermal protection applications?
As a thermal protection film, QuadZero TPS GR 400's core function is limiting heat transfer across the construction. A thermal conductivity of 0.044 W/m·K at 25°C allows the film to act as an effective thermal barrier and heat shield at a total thickness of only 838 µm (33 mil), which is critical for weight- and space-constrained applications such as aerospace, defense, and electronics/battery thermal management.
What is the temperature range for QuadZero TPS GR 400?
QuadZero TPS GR 400 remains stable to a glass transition temperature (AeroZero Tg, DMA) of 305°C (580°F), with decomposition onset (10 wt% loss, TGA) at 425°C (797°F).
Is QuadZero TPS GR 400 suitable for flame-rated aerospace and defense environments?
Yes. QuadZero TPS GR 400's graphite face layer carries a UL94 V-0 flammability rating and complies with the 60 Second Vertical Burn test, supporting its use in aerospace thermal barrier, defense thermal protection, and spacecraft/reentry vehicle applications.
How should QuadZero TPS GR 400 be specified?
Specify grade (QuadZero TPS GR 400), thickness, adhesive type, compliance requirements, dimensional tolerances, and finished format.
