Aerogel Felt

The verified Qiyao product language for aerogel felt is “low thermal conductivity.” No numeric thermal conductivity value is published in the source facts. That absence is itself procurement information. “Low thermal conductivity” is a qualitative descriptor, not a measurable material property. It cannot be converted into W/m·K, R-value, U-value, or a comparison with VIP. If a project requires a lambda value, the verified data does not supply one for aerogel felt. The buyer must request the current technical data sheet for the specific aerogel SKU or test the supplied material.

The aerogel line has 140 products on sale on Made-in-China as of 2026-10-11. The referenced product names show the formats in the line: “Low Thermal Conductivity Aerogel Blanket Aerogel Thermal Insulation Felt,” “Aerogel Insulation Pad for Battery Cell Insulation” (from $12.35/pc), and “Aluminum Faced 3mm 6mm 10mm Silica Aerogel Insulation Blanket.” These names establish blanket, felt, pad, and aluminum-faced blanket formats. The battery-cell pad name establishes one application: battery cell insulation. The provided names do not establish pipeline or building-service use; those applications should be confirmed on the specific SKU page rather than inferred from the general term “aerogel felt.”

Some aerogel products note “thickness available in customized options.” That is a customization statement, not a published standard thickness list. The “Aluminum Faced 3mm 6mm 10mm Silica Aerogel Insulation Blanket” name does list 3 mm, 6 mm, and 10 mm as available options for that product. It does not mean every aerogel felt SKU is available in those thicknesses, nor does it publish thermal performance by thickness. The from $12.35/pc price is attached to “Aerogel Insulation Pad for Battery Cell Insulation” in the source facts; it is a starting price for that referenced product, not a price for all aerogel products.

Aerogel felt is typically handled as a flexible or semi-rigid blanket material, but the verified data does not specify compressive strength, density, hydrophobicity, maximum service temperature, or fire performance. Those properties affect whether a felt or blanket is suitable for a given assembly. The product count of 140 indicates a broad line, but breadth is not a substitute for a data sheet. For a technical submittal, the useful documents would be the SKU-specific datasheet, thickness availability, and any test reports the supplier can provide for that exact product. The verified facts here do not include those documents.

The application evidence in the names is therefore narrow and specific: battery-cell insulation is named; blanket, felt, and aluminum-faced blanket formats are named. General building or pipeline use is not named in the verified product names supplied. If a website page needs application copy, it should link the claim to the SKU name or to a datasheet, not to the phrase “low thermal conductivity” alone.

Limit: The published data does not tell you the aerogel’s numeric thermal conductivity, thickness-specific performance, density, compression behavior, or system performance.
