AeroZero® Polyimide Aerogel Low Outgassing Configurations – Acrylic Adhesive AZ-TPS 102 / AZ-TPS 103 / AZ-TPS 104
AZ-TPS 102, AZ-TPS 103, and AZ-TPS 104 are the Low Outgassing Configurations of the AZ-TPS product line, each combining a 165 micron (6.5 mil) AeroZero® polyimide aerogel film with an acrylic pressure-sensitive adhesive (PSA) bonding layer sized to the specific grade, yielding total construction thicknesses of 223.5 µm (8.8 mil), 292.1 µm (11.5 mil), and 190.5 µm (7.5 mil) respectively. All three grades meet NASA ASTM E595 low-outgassing criteria (TML <1%, CVCM <0.1%) and deliver thermal conductivities between 0.037–0.049 W/m·K with a 305°C (580°F) glass transition temperature. The grades differ primarily in acrylic adhesive thickness and the resulting bond strength, tensile performance, and total film thickness.

AZ-TPS 102, AZ-TPS 103, and AZ-TPS 104 make up the Low Outgassing Configuration set within Blueshift Materials’ AeroZero® AZ-TPS product portfolio, each built around the same 165 micron (6.5 mil) AeroZero® polyimide aerogel film paired with a grade-specific acrylic pressure-sensitive adhesive layer. The three grades are designed to give fabricators a way to trade off adhesive bond strength against total construction thickness and weight while holding thermal performance and vacuum-compatibility constant: AZ-TPS 102 uses a 50.8 micron (2 mil) acrylic layer, AZ-TPS 103 steps up to a 127 micron (5 mil) layer, and AZ-TPS 104 uses the thinnest 25.4 micron (1 mil) layer.
Mechanically and thermally, the three grades track closely — glass transition temperature holds at 305°C (580°F) across all three, while tensile strength, elongation, density, basis weight, decomposition temperature, and peel adhesion vary with the adhesive layer thickness, as shown in the Specifications tables below. All three grades are qualified to NASA ASTM E595 low-outgassing criteria (Total Mass Loss under 1%, Collected Volatile Condensable Material under 0.1%), making them suited to vacuum-compatible aerospace, defense, and electronics assemblies where material volatility is a design constraint. Each grade bonds to stainless steel, aluminum, glass, carbon fiber, and polymer substrates such as polyimides, polyether ketones, polyurethanes, and polyesters, using a peel-away release liner and reaching optimal adhesion after a 3-day room-temperature dwell.
Compliant with NASA ASTM E595.
What differentiates AZ-TPS 102, AZ-TPS 103, and AZ-TPS 104 from one another?
All three share the same 165 micron (6.5 mil) AeroZero® aerogel film and 305°C (580°F) glass transition temperature, but use different acrylic adhesive thicknesses — 50.8 micron (2 mil) for AZ-TPS 102, 127 micron (5 mil) for AZ-TPS 103, and 25.4 micron (1 mil) for AZ-TPS 104. AZ-TPS 103's thicker adhesive layer gives the highest total thickness but the lowest peel strength and tensile strength of the three; AZ-TPS 102 and AZ-TPS 104 both deliver higher peel strength (>300 N/m) in thinner, lighter-weight constructions.
Why does thermal conductivity matter in material selection for AZ-TPS 102, 103, and 104?
As thermal protection films, these grades are selected to limit heat transfer into the substrates they're bonded to. Thermal conductivity ranges from 0.037 W/m·K (AZ-TPS 104) to 0.049 W/m·K (AZ-TPS 103) at 25°C, directly determining how effectively each construction insulates aerospace, defense, and electronic components — a key factor alongside adhesive strength when selecting among the three grades.
What is the temperature range for AZ-TPS 102, AZ-TPS 103, and AZ-TPS 104?
All three grades share a glass transition temperature (AZ Tg, DMA) of 305°C (580°F). Decomposition temperature (10 wt% loss, TGA) varies by grade: 261°C (501.8°F) for AZ-TPS 102, 273°C (523.4°F) for AZ-TPS 103, and 255°C (491°F) for AZ-TPS 104.
Are AZ-TPS 102, AZ-TPS 103, and AZ-TPS 104 suitable for vacuum-compatible aerospace environments?
Yes. All three grades are compliant with NASA ASTM E595, with Total Mass Loss (TML) under 1% and Collected Volatile Condensable Material (CVCM) under 0.1%, qualifying them for vacuum-compatible aerospace, defense, and electronics applications.
How should AZ-TPS 102, AZ-TPS 103, or AZ-TPS 104 be specified?
Specify grade (AZ-TPS 102, AZ-TPS 103, or AZ-TPS 104), thickness, compliance requirements, dimensional tolerances, and finished format.
