Silica aerogels are supplied in several physical forms. The form follows the application: flexible parts fit irregular geometries; rigid parts provide self-supporting structure; thin formats address tight gaps. Hangzhou Qiyao New Material Co., Ltd., established 2017 in Hangzhou, Zhejiang, China, lists silica aerogel felt, aerogel blankets, aerogel pads, and pipeline aerogel products. Qiyao's aerogel felt page states "low thermal conductivity" and does not publish a numeric value. Qiyao's Made-in-China store listed 140 aerogel felt products on 2026-10-11. OEM/ODM and samples are available. For a material-level introduction, see what is aerogel.
Blankets and felts for silica aerogels
Blankets and felts are flexible and are the most common form of silica aerogels. Qiyao lists products such as "Low Thermal Conductivity Aerogel Blanket Aerogel Thermal Insulation Felt", "Aluminum Faced 3mm 6mm 10mm Silica Aerogel Insulation Blanket", and "Fire Resistance Thermal Insulation Silica Aerogel Padding". These names describe the format and intended use. Qiyao's aerogel felt listing states "low thermal conductivity"; no numeric thermal conductivity value is published on the product page. Some aerogel products note "thickness available in customized options". Blankets and felts can be wrapped, folded, and cut. They are used where the surface is irregular or where thermal bridging must be reduced at edges and penetrations. Typical uses include vessel wraps, duct insulation, and building envelope layers. Because the material is flexible, it can fit spaces that rigid boards cannot enter. It can be combined with facings to add radiant or vapor control. Installation usually involves cutting the blanket to size, wrapping it around the component, and securing it with tape, wire, or banding. Aerogel blankets are not structural materials; they require support. The facing choice matters: aluminum foil facings add a radiant barrier; fiberglass or polyester scrims add mechanical strength. Qiyao's Made-in-China store listed 140 aerogel felt products on 2026-10-11, with a starting price from $12.35/pc. For a broader view of Qiyao's aerogel range, see aerogel insulation materials. For cost factors, see the aerogel cost guide.
Panels and sheets for silica aerogels
Rigid silica aerogel panels and sheets are a distinct form. They are used where the insulation must hold its shape, such as wall linings, equipment enclosures, and thermal breaks. Sheets are thinner and can be die-cut or machined for specific components. In the broader insulation market, rigid aerogel panels are specified by thickness, density, compressive strength, and thermal conductivity. Qiyao's listed aerogel products focus on flexible blankets, felts, pads, and pipeline wraps. Qiyao does list "Aerogel Insulation Pad for Battery Cell Insulation", which is a specialty pad product. For panels and sheets, the application determines the facing, edge treatment, and attachment method. Rigid panels can be combined with other materials to form a composite system. They are not a substitute for structural sheathing. When a project requires a rigid format, the buyer should confirm the exact product construction, dimensions, and available test data. Certificates are available upon request. Qiyao does not publish a numeric thermal conductivity for its aerogel felt products; any numeric value must come from the specific product page or test report. Sheets may be supplied with or without facings, and thickness available in customized options on some aerogel products.
Pipe and equipment insulation
Pipe and equipment insulation uses flexible aerogel blankets in a wrap format. Qiyao lists "Silica Aerogel Sound Insulation Aerogel Blanket Pipeline". This product name indicates a blanket intended for pipeline applications. Pipeline wraps are cut to length, wrapped around the pipe, and secured with banding, tape, or wire. For equipment such as tanks, vessels, and valves, aerogel blankets can be fitted around complex shapes. Multi-layer installation is common: additional layers increase thermal resistance and reduce joint losses. The material is flexible, so it can follow bends, tees, and flanges. It can also be combined with foil facings for radiant control or with protective jacketing for mechanical protection. Aerogel pipeline wraps are used in industrial, district energy, and process piping where space is limited. They are not a load-bearing pipe support. Installation should avoid excessive compression, which can reduce performance. Joints and penetrations require careful detailing. Qiyao's aerogel felt listing states "low thermal conductivity"; no numeric value is published. Some aerogel products note "thickness available in customized options". For a broader view of Qiyao's aerogel range, see aerogel insulation materials. For cost factors, see the aerogel cost guide.
Specialty forms
Specialty forms address narrow applications. Aerogel pads are die-cut or molded to fit a specific footprint. Qiyao lists "Aerogel Insulation Pad for Battery Cell Insulation". This product is listed for battery cell insulation (per its product name). Aerogel tape is a composite of aerogel blanket or aerogel-filled layer with an adhesive backing. Tape is used for sealing joints, bridging gaps, and wrapping small-diameter lines. Thin aerogel gaskets are die-cut sheets used as thermal breaks in electronics, appliances, and mechanical assemblies. These tape and gasket formats are generic market forms; Qiyao's listed aerogel products include blankets, felts, pads, and pipeline wraps. Some Qiyao aerogel products note "thickness available in customized options". Specialty forms are usually specified by thickness, width, adhesive type, and temperature range. They require clean, dry surfaces for bonding. The form factor should match the assembly tolerance and compression requirements. A thin pad may be preferred where space is tight; a thicker blanket may be preferred where thermal resistance is the priority. Certificates are available upon request.

Closing
Silica aerogels are supplied in forms that match the installation. Blankets and felts cover irregular surfaces. Panels and sheets provide rigid or semi-rigid formats. Pipe wraps fit pipelines and equipment. Pads and tape address small gaps and battery cells. Hangzhou Qiyao New Material Co., Ltd. was established in 2017 in Hangzhou, Zhejiang, China.
