Firstly, glass wool belongs to a category under glass fiber and is an artificial inorganic fiber. Glass wool is a material that transforms molten glass into a cotton like structure. Its chemical composition belongs to the glass class and it is an inorganic fiber. It has the characteristics of good molding, low bulk density, high thermal conductivity, thermal insulation, good sound absorption performance, corrosion resistance, and stable chemical properties. Therefore, glass cotton quilts are widely used as insulation materials for houses and have excellent cost-effectiveness. In addition, it is also a non flammable material that does not deteriorate over time and is also very friendly to the body. So currently, it has become a common environmentally friendly residential insulation material and an indispensable part of houses.

Classification of glass wool and its products

The most widely used glass wool products on the market currently include cotton felt, cotton board, cotton shell, etc. These products use adhesives such as phenolic resin and biobased adhesives. According to different uses, the type and moisture content of the adhesive used also vary, resulting in different specifications, shapes, and even properties of the glass wool products produced.
Common categories of glass wool products.

Application scope of glass wool and its products

1、 In terms of architecture
In terms of construction, glass wool and its products are widely used as excellent insulation and sound insulation materials in buildings. As early as 2017, the amount of building insulation materials used in developed countries abroad accounted for 75% -80% of the total amount of insulation materials. For example, in West Germany, glass wool felt with thicknesses of 2, 3, 4, and 5 centimeters is commonly used, and its insulation capacity is equivalent to that of solid brick walls with thicknesses of 50, 75, 100, and 125 centimeters. By using glass wool as a material, not only can the weight of the building be greatly reduced, but it can also save a lot of fuel, which makes it increasingly widely used in industrial and residential buildings.
2、 Transportation and Communications
In terms of transportation, glass wool and its products are increasingly being used as insulation materials by transportation vehicles such as airplanes, trains, cars, and ships. For example, the engines, waste heat pipes, and insulation and sound insulation inside the aircraft cabin are all made of ultra-fine cotton, high-temperature cotton felt, and cotton boards; In foreign countries, cotton felt, cotton board, and other insulation materials have been widely used for the roof, carriage walls, floors, and high-temperature parts of locomotives.
3、 Refrigeration
In terms of refrigeration, glass wool is often used as a thermal insulation material in refrigerated trucks and refrigerated vehicles. In addition, it is also widely used in refrigerated warehouses.
4、 In terms of power and chemical equipment and pipelines
Glass wool products are also widely used in power, chemical, metallurgical, petroleum, and other industrial sectors. For example, the boilers and cooling systems in these departments use glass wool products instead of diatomaceous earth, asbestos soil, etc. as insulation materials for thermal insulation and prevention of condensation and freezing. This not only has a good effect, but also is easy to install and has a long service life. Using glass wool products as insulation layers on pipelines can not only provide thermal insulation, but also prevent moisture and corrosion.
5、 Liquefied natural gas field
In the field of liquefied natural gas, glass wool products are also used as insulation materials for LNG storage tanks, effectively reducing pipeline losses, improving overall operational efficiency, and ensuring safety. Taking the LNG storage tank elastic felt of Zaisheng Technology as an example, it can not only maintain the tightness and uniformity required for cold insulation, but also facilitate later construction and maintenance.
