What Is Polyurethane Molding?
Polyurethane molding is a process of producing polyurethane resin by reacting polyol and isocyanate.
There are primarily two methods of molding: high-pressure foam molding and injection molding. In high-pressure foam molding, polyol and isocyanate are mixed and injected into molds under high pressure to foam. On the other hand, in injection molding, the mixed raw materials are injected into molds using an injection machine and then solidified. In both methods, polyurethane resin is formed through a chemical reaction.
Polyurethane molding has applications in various fields such as automotive parts, household appliances, furniture, construction materials, medical devices, and sports equipment. Its features include high flexibility in shape, lightweight nature, thermal insulation, impact resistance, and chemical resistance.
