[0002] Polyurethane resin is a thermosetting plastic with good physical and chemical properties. It has the characteristics of high strength, wear resistance, chemical corrosion resistance, and good heat resistance. Polyurethane resin can be used to make foams, coatings, adhesives, and elastic materials. The preparation method of polyurethane resin is usually achieved through polymerization reaction. Isocyanate is reacted with polyol to generate prepolymers of organic amines and alcohols, and then reacted with chain extenders to form polyurethane resin. This substance may produce toxic gases during the preparation process. Operations should be carried out in a well-ventilated environment and appropriate protective equipment should be used. Polyurethane resin may decompose at high temperatures to produce toxic gases, and direct exposure to open flames should be avoided.
