Flexible PET Cryogenic Aerogel Insulation Blanket-AG20

Product Description

AG20 is a flexible PET aerogel blanket engineered for cold and cryogenic insulation. A PET and glass-fiber substrate is combined with aerogel through a sol-gel process, followed by supercritical extraction to remove solvents. The result is a conformable, easy-to-handle blanket that pairs its fibrous reinforcement with the low heat-transfer characteristics of a nanoporous aerogel network.

Depending on its formulation, silica aerogel typically contains 80–99.8% pore volume, with nanoscale pores spanning a broad 1–100 nm range. These confined pores restrict gas-molecule movement and suppress gas-phase heat conduction through the Knudsen effect. Within the AG20 composite, this material structure supports a published thermal conductivity of 0.016–0.022 W/(m·K) at 25°C while retaining the flexibility needed around pipes, tanks and complex equipment.

Conventional cold-insulation systems can become bulky, stiff at low temperature, or vulnerable to moisture uptake and aging. AG20 is designed to address these practical limitations with a thin profile, deep-cold flexibility and a hydrophobic core. Its applications cover LNG pipelines, transport vessels, storage tanks and receiving terminals; liquid nitrogen and ethylene service; low-temperature process equipment; and temperature-controlled food and pharmaceutical logistics.

Liquid Nitrogen Pipelines, Storage Tanks	-196°C	Liquid Ethylene	-104°C
Medical Field	-70°C to -80°C	Food Cold Storage & Transport	-18°C to -30°C

Cold-Chain Energy Efficiency & Space Optimization

Refrigeration energy is closely tied to the heat entering a cold room, refrigerated vehicle or cryogenic system. Every unit of heat that crosses the envelope must be removed again by the cooling equipment. By limiting that heat gain, AG20 can help reduce compressor duty and the indirect carbon emissions associated with electricity use, while supporting more stable temperature control.

Cold rooms and food or pharmaceutical logistics: A thinner, hydrophobic insulation layer can help maintain low temperatures without giving up as much usable storage volume. In suitable comparisons, AG20 can reduce insulation thickness by approximately 30–50% relative to conventional material build-ups.
LNG and industrial-gas facilities: AG20 covers service points such as LNG at -162°C and liquid nitrogen at -196°C within its published -200 to 125°C range. Its flexibility suits tanks, piping, terminals and equipment where thermal movement and complex geometry must be accommodated.
Marine and refrigerated transport: Low bulk and conformability are valuable for vehicle bodies, vessel insulation and mobile cryogenic equipment, where payload space and maintenance access are important.

How to interpret cold-store energy-saving figures. Some industry reports quote energy reductions of 30–45% after high-performance cold-storage insulation upgrades. These are application-level reference figures, not a guaranteed result for every AG20 installation. Actual savings depend on the existing envelope, air leakage, door openings, vapor-barrier continuity, temperature set-point, operating schedule and refrigeration efficiency. Anchor-Aerogel can review the material thickness and insulation build-up against your project data.

Comparison of Thermal Conductivity

AG20 has a published thermal conductivity of 0.016–0.022 W/(m·K) at 25°C, below the typical ranges shown for rock wool and glass fiber in the comparison table. In suitable designs, equivalent thermal resistance can be achieved with approximately 30–50% less insulation thickness; the actual build-up depends on the reference material, temperature difference and required heat-leak or surface-temperature target.
In low-temperature testing cited for AG20, tensile strength remained above 0.52 MPa at -150°C, water absorption was below 3%, and performance degradation after cyclic freezing was below 5%. Request the current TDS or project documentation for design-critical values.

Product Advantages

Efficient insulation with less bulk: AG20 combines a published conductivity of 0.016–0.022 W/(m·K) at 25°C with a thin, flexible format. Where the design permits, it can reduce the required insulation build-up by approximately 30–50% compared with conventional material systems while maintaining equivalent thermal resistance. This can free up usable space in cold rooms and refrigerated vehicles and simplify installation around congested LNG equipment.
Deep-cold flexibility: The published AG20 operating range is -200 to 125°C, covering typical LNG service at -162°C and liquid-nitrogen service at -196°C. The blanket remains flexible in deep cold and accommodates stress caused by thermal expansion and contraction without contraction joints, helping simplify installation and maintenance.
Physical strength and reuse: The PET aerogel blanket has a compressive strength of 0.5–1.0 MPa and a stated service life of over 20 years. It can be removed and reused where its condition permits, making inspections and repairs more practical and reducing maintenance downtime.
Hydrophobic, moisture-resistant core: AG20 is 99% hydrophobic and has a stated water absorption rate below 3%. This helps limit liquid-water uptake and supports corrosion-under-insulation control in humid or wet environments. A complete system still requires correctly detailed vapor sealing and jacketing.
Easy to fabricate and install: The lightweight blanket can be cut or sewn to fit pipes, tanks and equipment with irregular geometry. Its flexibility and standard roll format help reduce fabrication time and simplify handling on larger projects.

Manufacturer & Engineering Notes

Manufacturing & Project Experience

Anchor-Aerogel developed AG20 specifically for cryogenic duty, bonding aerogel to a PET and glass fiber substrate through sol-gel processing and supercritical extraction. We support LNG, industrial gas, and cold chain projects with standard 5/10 mm rolls, customized thicknesses, qualification samples, and technical review of piping and tank insulation layouts against drawings. The comparison and low-temperature test data on this page, including tensile strength at -150°C and cyclic freezing results, come from our own testing; project-specific design values are confirmed in the current TDS or formal technical documentation before order acceptance.

Engineering Boundaries & Custom Options

Standard AG20 is a flexible blanket with a published operating range of -200 to 125°C, nominal density of 160 kg/m³, 5/10 mm thickness (customizable), 1500 mm width, 99% hydrophobicity, and conductivity of 0.016–0.022 W/(m·K) at 25°C. Use the current TDS as the governing document, especially near either temperature limit. The blanket stays flexible in deep cold, needs no contraction joints, and can be reused after disassembly where its condition permits. It is not load-bearing; compressive strength is 0.5–1.0 MPa. Vapor-barrier continuity and protective jacketing remain part of the system designer's responsibility.

Qualification & Lifecycle Value

Aerogel generally has a higher initial material cost than commodity insulation, and some cold-chain applications still have limited standardized design guidance and long-term field data. Evaluate AG20 on total installed value—including space recovered, refrigeration demand, maintenance and service life—rather than material price alone. For new duties, qualify the complete system using the current TDS, samples, thermal and vapor-control calculations, and defined inspection criteria. Continued development of lower-cost production methods and application-specific insulation systems will be important to broader adoption.

Frequently Asked Questions about PET Cryogenic Aerogel Blanket (AG20)

Technical answers for overseas buyers, engineers, and project specifiers. For project-critical values, request the current TDS before final design.

What cryogenic applications is the AG20 PET aerogel blanket designed for?

AG20 is developed for cold insulation on LNG pipelines, carriers, storage tanks and receiving-station equipment; liquid nitrogen and liquid ethylene service; low-temperature process equipment; and food or pharmaceutical cold chains, including cold rooms and refrigerated vehicles. Typical reference points include LNG at -162°C, liquid nitrogen at -196°C, liquid ethylene at -104°C, liquid oxygen at -183°C, and food cold storage or transport at -18 to -30°C. The blanket remains flexible in deep cold within its published operating range.

What is AG20 made of, and why does it suit cryogenic service?

AG20 uses a PET and glass-fiber substrate combined with aerogel through a sol-gel process followed by supercritical extraction. The aerogel’s nanoscale pore network restricts gas-phase heat transfer through the Knudsen effect, while the fibrous substrate provides handling flexibility. Unlike brittle or moisture-sensitive insulation systems, the blanket is designed to remain flexible at low temperature, accommodate thermal movement and resist liquid-water uptake. Testing cited on this page shows tensile strength above 0.52 MPa at -150°C and performance degradation below 5% after cyclic freezing.

What temperature range, thermal conductivity, and thickness does AG20 offer?

The specification table lists an applicable temperature range of -200 to 125°C, thermal conductivity at 25°C of 0.016–0.022 W/(m·K), nominal density of 160 kg/m³, hydrophobicity of 99%, and chloride ion content of 0.001%. Standard thicknesses are 5 mm and 10 mm, or customized, at 1500 mm width. In suitable designs, equivalent thermal resistance can be achieved with approximately 30–50% less insulation thickness, subject to project-specific calculation.

How does AG20 compare with traditional cold insulation materials?

Per the comparison table on this page, AG20 delivers thermal conductivity of 0.016-0.022 W/(m·K) against 0.025-0.035 for polyurethane foam, 0.040-0.045 for rock wool, and 0.035-0.050 for glass fiber, with compressive strength of 0.5-1.0 MPa and a stated service life of 20 years versus 8, 5, and 10 years respectively. It addresses common failure modes of traditional materials: excessive thickness requirements, loss of elasticity and breakage at low temperature, aging, and poor hydrophobicity leading to water-ingress corrosion. Water absorption is below 3%.

What installation and maintenance advantages does AG20 offer on LNG and cold service?

AG20 is a lightweight, flexible blanket that can be cut or sewn to fit pipes and equipment of various shapes, reducing installation time on large-scale projects. Because it tolerates thermal contraction stress without contraction joints, installation can be simpler and maintenance points fewer. The blanket can be reused after disassembly where its condition permits. Its hydrophobicity and stated water absorption below 3% help control moisture-related deterioration and corrosion under insulation. Vapor sealing and jacketing details should still follow the project’s cryogenic insulation specification.

Cryogenic Insulation Blanket Performance Below -100°C

For cold-service lines, insulation must retain its thermal and mechanical performance through repeated temperature cycles. AG20 combines a silica aerogel network with a PET and glass-fiber substrate, with a published operating range of -200 to 125°C and thermal conductivity of 0.016–0.022 W/(m·K) at 25°C.

Two important specification checks are moisture behavior and chloride content. AG20 is 99% hydrophobic and has stated water absorption below 3%, helping the blanket resist liquid-water uptake in humid or wet service. Chloride ion content is 0.001%, an important consideration for stainless-steel equipment where chloride contamination can contribute to stress corrosion cracking. Hydrophobicity alone does not replace a continuous vapor barrier: the complete insulation system must control vapor ingress, joints and terminations.

Nominal density is 160 kg/m³, with 5 mm and 10 mm thicknesses supplied on 1500 mm wide rolls. The flexible blanket conforms to valves, elbows and small-diameter lines; project-specific vapor sealing and protective jacketing should be installed where required by the service conditions.

Typical cold-service points are LNG at -162°C, liquid nitrogen at -196°C, liquid oxygen at -183°C and liquid ethylene at -104°C, across terminal piping, storage tanks, loading arms and cold-chain transport equipment. For the pipeline side of the same job, the low-temperature pipeline application guide covers thickness selection and CUI control in more detail.
