1, glass wool insulation
Glass wool is a category of glass fibers and is a type of artificial inorganic fiber. Glass wool is a material that melts glass fiber to form a cotton-like material. Its chemical composition is glass. It is an inorganic fiber. It has a good shape, small bulk density, high thermal conductivity, thermal insulation, good sound absorption, and corrosion resistance. Decoration, chemical stability. Generally used in high-temperature steam insulation pipe, steel jacket steel insulation pipe, insulation oil casing coupling.
2, polyurethane foam insulation
Polyurethane foam is a kind of special polyurethane product filled with polyurethane prepolymer, foaming agent, catalyst and other components in pressure aerosol cans. When the material is sprayed from the aerosol can, the foamed polyurethane material will rapidly expand and react with air or contact with the moisture in the matrix to form a foam. Cured foam has a variety of effects such as caulking, bonding, sealing, heat insulation, sound absorption, etc. It is an environmentally friendly, energy-saving and easy-to-use building material. It can be used for sealing and plugging, filling in air and repairing joints, fixing and bonding, and heat preservation. Soundproofing, especially suitable for sealing and waterproofing between steel or aluminum alloy doors and windows and walls
