Aerogel felt is a flexible thermal insulation material composed of aerogel microporous structure as its core, combined with glass fiber or ceramic fiber. It boasts low thermal conductivity, light weight, high temperature resistance, and good flexibility, making it an important thermal insulation material widely used in construction, industry, energy, and transportation in recent years. With its excellent energy-saving effect and adaptability, aerogel felt plays a crucial role in multiple scenarios.

I. High-Efficiency Thermal Insulation for Industrial Pipelines

The most typical application of aerogel felt is for the insulation of medium- and high-temperature pipelines in the petrochemical, chemical, and power industries. Its thermal conductivity is much lower than that of traditional insulation materials, achieving better insulation performance at the same thickness, helping to reduce energy loss; at the same time, its flexible structure facilitates the covering of complex parts such as pipe bends and valves.

II. Insulation Layers for Equipment Tanks and Towers

Aerogel felt

In equipment such as boilers, heating furnaces, storage tanks, and reaction towers, where temperature variations are large and shapes are complex, insulation materials that are both temperature-resistant and flexible are required. Aerogel felt can adapt to the thermal expansion and contraction of equipment, is not prone to cracking, and can reduce the thickness of the insulation layer, leaving more space for equipment.

III. Building Exterior Walls and Thin Insulation Systems

With the increasing standards for building energy efficiency, aerogel felt is increasingly used in exterior walls, curtain wall interlayers, roofs, and fireproof insulation areas. Due to its ultra-thin characteristics, it can achieve lower thermal conductivity in limited spaces, making it suitable for renovation projects or exterior wall insulation systems with limited space.

IV. Cold Insulation for Cryogenic Equipment such as LNG and Liquid Nitrogen

The microporous structure of aerogel felt also provides excellent cold insulation capabilities, making it suitable for cryogenic engineering projects such as LNG pipelines, cryogenic storage tanks, and refrigeration equipment. Its high stability and low water absorption rate make it less susceptible to condensation, helping to control cold loss and reduce condensation.

V. Thermal Insulation for Transportation Vehicles

In rail transit, commercial vehicles, and ships, aerogel felt can be used for engine compartment insulation, exhaust system covering, and vehicle body thermal protection. It is lightweight and has a wide temperature resistance range, reducing heat radiation in high-temperature areas and improving operational safety.

VI. Electronics, Photovoltaics, and New Energy Fields

Some precision equipment requires high temperature stability. Aerogel felt can be used in battery pack insulation, inverter heat dissipation isolation, and photovoltaic junction box protection. Its temperature resistance and thermal insulation properties can mitigate thermal shock and improve the long-term reliability of equipment.

VII. Fire Protection and Safety Applications

Due to its outstanding high-temperature resistance, aerogel felt can be used in fire insulation blankets, heat-resistant protective clothing, and fireproof partition materials. Its lightweight and flexible structure can maintain a certain level of thermal insulation in high-temperature environments, providing additional safety protection for personnel and equipment.
