Aerogel blanket

When selecting Aerogel Blankets, the most critical factor is Thermal Conductivity, which should typically range between 0.015 to 0.023 W/(m·k) at room temperature. You must also verify the Density (usually 160-220 kg/m³) and the Operating Temperature Range, ensuring the material can withstand environments from -200°C up to 650°C (or 1000°C for ceramic-based versions). Additionally, check for Hydrophobicity (water repellency); high-quality blankets should have a hydrophobic rate of ≥99% to prevent CUI (Corrosion Under Insulation).

For industrial and construction applications, ensure the product meets ASTM C1728 (Standard Specification for Flexible Aerogel Insulation). Fire safety is paramount, so look for Class A1 Non-combustibility ratings according to EN 13501-1 or ASTM E84. If the product is intended for the EU market, CE Marking and REACH/RoHS compliance are essential to ensure the absence of hazardous substances like asbestos or refractory ceramic fibers.

Aerogel is typically infused into a carrier fiber. Fiberglass substrates are the most common for standard industrial pipes and tanks due to their balance of cost and performance. Pyrolyzed Carbon or Pre-ox fibers are preferred for high-temperature or aerospace applications, while Polyester (PET) substrates are used for lower-temperature building insulation. Choosing the wrong substrate can lead to structural failure or melting if the ambient temperature exceeds the carrier fiber's limit.

Aerogel blankets are primarily used in Oil & Gas (subsea pipelines, refineries), District Energy (steam pipes), and Power Generation. They are also increasingly adopted in Electric Vehicle (EV) battery packs as thermal runaway barriers. Because they are 2-5 times thinner than traditional insulation (like rock wool), they are ideal for space-constrained environments where maximizing internal volume or reducing pipe rack footprints is necessary.

The biggest risk is material shedding and dust (friability). Low-quality aerogels may lose their nanoporous structure during transit, resulting in 'dusting' that reduces insulation value. Always request a Scanning Electron Microscope (SEM) image or a third-party thermal conductivity test report from a reputable lab. Another risk is counterfeit material, where standard felt is coated with silica powder rather than undergoing the supercritical drying process required for true aerogel.

Aerogel is a high-value commodity. Negotiate based on Volume (Cubic Meters) rather than just square meters to account for thickness variations. For large projects, aim for a 15-20% discount on orders exceeding 500 square meters. Request Tiered Pricing and ask the supplier if they can provide customized die-cutting services, which can reduce your local labor costs and material waste, providing better overall value.

Aerogel blankets are lightweight but bulky. To optimize shipping costs, use Vacuum Packaging to reduce volume, but ensure the supplier guarantees the material will rebound to its original thickness upon unpacking. Ensure the pallets are shrink-wrapped and moisture-proof, as prolonged exposure to high humidity during sea freight can affect the performance of the hydrophobic coating if the packaging is breached.

Utilize Secured Payment services provided by Made-in-China.com to protect your funds until delivery. It is highly recommended to hire a third-party inspection agency (like SGS or Intertek) to perform a 'Dusting Test' and 'Thickness Verification' at the factory before the final balance is paid. Ensure the Bill of Lading (B/L) clearly matches the technical specifications listed in the Proforma Invoice.
