1, glass wool insulation
Glass wool is a category of glass fibers and is an artificial inorganic fiber. Glass wool is a material that melts glass into a cotton-like material. Its chemical composition is glass. It is an inorganic fiber with good shape, small bulk density, thermal conductivity, thermal insulation, good sound absorption and corrosion resistance. Decorative and chemical properties are stable. Generally used in high temperature steam insulation pipe, steel sleeve steel insulation pipe, insulation oil casing coupling.
2, polyurethane foam insulation
Polyurethane foam is a special polyurethane product that packs polyurethane prepolymer, foaming agent, catalyst and other components into a pressure-resistant aerosol can. When the material is ejected from the aerosol can, the foamed polyurethane material rapidly expands and solidifies to react with the air or the moisture in the contacted matrix to form a foam. The cured foam has various effects such as caulking, bonding, sealing, heat insulation and sound absorption. It is an environmentally-friendly, energy-saving and easy-to-use building material, which can be applied to sealing and sealing, filling and filling, fixing and bonding. Sound insulation, especially suitable for sealing and waterproofing between plastic steel or aluminum alloy doors and windows and walls. Wide range of use and low cost!
