Aerogel insulation felt is a kind of flexible thermal insulation material. It is made by special process with silica aerogel as the main material and compounded in the reinforcing fiber. There are many types of reinforcing fibers, such as carbon fiber, glass fiber, and pre oxidized fiber.

Aerogel insulation felt features:

> Super Thermal Insulation Performance

> Long Lasting Heat Resistance

> Fireproof and Waterproof

> Tensile and Crack Resistance

> Environmental Protection

> Sound Resistance and Impact Resistance

> Easy To Install

Typical applications:

> Industrial pipelines, steam turbines, boilers, heat exchangers, high-temperature reaction and heating equipment, flues, industrial furnace bodies, power plant heating networks, direct-buried pipelines, and high-temperature steam pipelines.

> Application areas: Building energy saving, petrochemical industry, power heating network, solar thermal energy, chemical and pharmaceutical industry, industrial equipment.

Aerogel is currently known as a light solid material because of its unique properties in mechanics, acoustics, heat, optics and other aspects, such as nano porous structure (1-100nm), low density (1~500kg/m³), low dielectric constant (1.1~2.5), low thermal conductivity (0.013 ～0.025W/(m · K)), high porosity (80~99.8%), high specific surface area (200~1000m³/g) and other characteristics. It has broad and huge application prospects in many fields such as aerospace, military, transportation, communications, medical, building materials, electric power, metallurgy, etc. And it’s been called “the magical material that changes the world”.

Silica Aerogel is a material with good thermal insulation performance so far. Its pore size is lower than the mean free path of air molecules under normal pressure. Therefore, the air molecules in the aerogel pores are approximately static, thus avoiding the convective heat transfer of air. The extremely low volume density of aerogels and the curved path of the nano-network structure also prevent gas and solid heat conduction, and the “infinitely many” void walls can reduce heat radiation. These three aspects work together to block almost all the ways of heat transfer, so that aerogel can achieve a thermal insulation effect those other materials can’t match, even far lower than the thermal conductivity of static air at room temperature of 0.025W/m·K, reaching 0.013W /m·K or less.
