First, the introduction Polyurethane foam is mainly used for building insulation and insulation materials. Polyurethane foams are classified into rigid polyurethane foams, semi-rigid polyurethane foams, and flexible polyurethane foams. Rigid polyurethane foam is mainly used for building insulation materials, insulation materials (insulation of pipeline facilities, etc.), household items (insulation and core materials for refrigerators, air conditioners, etc.), and transportation vehicles (cars, aircraft cushions, ceilings) )Wait. Polyurethane foam Second, hidden dangers Polyurethane foam has become a new favorite in the field of industrial building materials due to its soft, wear-resistant and heat-insulating properties, and several fires have made this new material uncertain. â— The use of a large amount of flammable materials such as polyurethane foam is an important cause of the rapid spread of fire. â— Once this material is burned, it will produce a gas containing highly toxic hydrogen cyanide, which will die if inhaled. â— Since polyurethane is a high polymer, the circulation in the body is very slow. Once invaded into the human body, it is toxic to the liver and easily induces tumors. Polyurethane exterior wall insulation Third, the prospects However, polyurethane foam as a high-quality material for exterior wall insulation will have a good application prospect. Energy-saving buildings will also become the future demand growth point of polyurethane raw material polymerization MDI and rigid foam PPG in the next few years, but only if it is used. The improvement of specifications and defect attributes is guaranteed.
