What is the purpose of polyurethane foam?
The adhesive properties of polyurethanes ensure a firm bond between the inner and outer walls, and also help prevent heat exchange between the interior and exterior . Polyurethane insulation also provides structure, in addition to insulating . The mechanical strength of these foams is remarkable because high compressive and shear strengths allow low-density insulating cores to be faced with relatively thin steel or aluminum, yet span long distances unsupported. The foam can hold together many of the components in a refrigerator or hot water heater and help carry the loads of the cabinet and contents, while it continues to perform as thermal insulation. This unique combination of properties allows rigid polyurethane foams to be used in many diverse applications.
