Aerogel Insulation Blanket 0.018 W/mK

Overview

Why Aerogel Blanket Is the Best Insulation Material Ever Produced

Aerogel is the lowest thermal conductivity solid material known to science — holding 15 Guinness World Records, used on Mars rovers and deep-sea pipelines alike. With thermal conductivity as low as 0.018 W/(m·K) (some grades reaching 0.012), aerogel blanket delivers 2–4 times the insulation performance of traditional materials like mineral wool, calcium silicate, or fiberglass in a fraction of the thickness. A single 10mm layer of aerogel blanket replaces 50mm of conventional insulation — saving space, weight, and installation labor while delivering superior thermal performance.

◆ 0.018 W/(m·K) — 2–4× Traditional Insulation. At equivalent thickness, aerogel blanket provides 2–4 times better thermal insulation than mineral wool, fiberglass, or calcium silicate. The nano-porous SiO₂ structure (>90% air, pore size 20–50nm) blocks all three heat transfer mechanisms: conduction through the solid skeleton, convection trapped in nanopores, and radiation scattered by the silica matrix. In practice, this means you can achieve the same thermal performance with a fraction of the thickness — freeing valuable space in tight industrial installations.

◆ Hydrophobic — The CUI Solution. Corrosion Under Insulation (CUI) is the #1 hidden maintenance cost in oil & gas and petrochemical plants — water ingress through traditional insulation causes steel pipe corrosion that goes undetected for years. Our aerogel blanket is inherently hydrophobic, repelling liquid water while allowing water vapor to pass. This prevents moisture accumulation at the pipe surface, directly eliminating the CUI failure mechanism.

◆ −200°C to 650°C — One Material, Full Temperature Range. Aerogel blanket is the only insulation material that handles cryogenic LNG (−200°C) and high-temperature steam (650°C) with a single product. No need for different insulation materials at different temperature zones. A1 fire rating ensures safety in the most demanding industrial environments.

◆ Flexible Blanket — Easy to Cut, Wrap, and Install. Unlike rigid calcium silicate boards or brittle mineral wool, aerogel blanket is a flexible, fabric-like material that wraps around complex geometries — valves, flanges, elbows, and irregular equipment. Can be cut with simple tools. Compression-resistant, dust-free, and non-irritating to skin — reducing PPE requirements and improving installation speed by up to 50% compared to rigid insulation.

◆ Space & Weight Savings. Achieving the same thermal performance requires approximately 80% less thickness and 85% less weight than traditional pipe insulation. For congested pipe racks, offshore platforms, and submarine installations, this space and weight saving directly reduces structural support costs, transport logistics, and installation labor. In battery pack applications, aerogel blanket's ultra-thin profile enables higher energy density within the same physical volume.

Application Scenarios

Oil, Gas & Petrochemical Pipe Insulation. Aerogel blanket wraps steam pipes, process lines, and transfer pipelines in refineries where space is constrained and CUI is a constant threat. Hydrophobic aerogel blanket eliminates moisture-driven corrosion while reducing insulation thickness by 80% on congested pipe racks.

EV Battery Thermal Protection. Ultra-thin aerogel blanket (3–6mm) provides thermal runaway barrier between battery cells and modules. A1 fire rating ensures no flame propagation. The space-saving profile enables higher energy density packaging without compromising safety — critical for next-generation EV platforms.

LNG & Cryogenic Systems. Aerogel blanket is the only flexible insulation that performs from cryogenic LNG temperatures (−200°C) to ambient without cracking or losing thermal performance. Used on LNG storage tanks, transfer lines, regasification equipment, and cold boxes.

Industrial Furnace & High-Temp Equipment. Aerogel blanket withstands continuous 650°C on furnace walls, boiler casings, and heat treatment equipment. 10mm replaces 50mm of ceramic fiber or calcium silicate — valuable space savings around high-temperature process equipment.

Offshore & Marine Insulation. 85% lighter weight dramatically reduces structural load on offshore platforms and FPSO vessels. Hydrophobic aerogel blanket repels seawater spray and prevents CUI in marine environments. Flexible form wraps complex offshore pipe geometries without custom fabrication.
