Aerogels are low-density three-dimensional nanoporous solid materials whose pores are filled with gaseous media and whose pores are filled with gaseous media. The 250th issue of the world's top authoritative academic magazine Science listed aerogel as the top ten new materials. It is called the "magical material that changes the world" and also known as the "ultimate thermal insulation material". It is currently the lightest solid material and has broken 15 Guinness records. Aerogels have three-dimensional nano-network porous structure and physical characteristics such as low density, high specific surface area, high porosity, low dielectric constant, and low thermal conductivity. They have wide application prospects in thermal insulation, fire prevention and flame retardant, sound insulation and noise reduction, optics, electricity and other fields.

The aerogel felt product developed and produced by Honghui Technology is a soft, hydrophobic, high-temperature stable, fire-retardant, and non-powder-losing thermal insulation felt made by using proprietary technology to compound nano-porous aerogel and fiber materials. The special process makes the aerogel felt have extremely low thermal conductivity, small density, excellent overall hydrophobic properties, and a fire retardant rating that can reach A1 standards. It is a non-combustible material. It has no powder falling off during transportation and use, and is green and environmentally friendly. At the same time, it also has superior sound insulation, noise reduction, pressure and vibration reduction characteristics. Products are widely used in *, * and national defense, petrochemical pipelines, building insulation, power grids, vehicle transportation, refrigeration and cold chain, daily insulation and many other fields.
