Depending on the type of polyol and isocyanate used the generated foam exhibits different properties. By careful selection of the polyol and isocyanate, foam with varying properties can be generated. It could be soft and flexible with totally open cells, which are used in the furniture industry to very hard dense wood like closed cell rigid foam.
Polyurethane foam is widely used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires, automotive suspension bushings, electrical potting compounds, seals, gaskets, carpet underlay, and hard plastic parts (such as for electronic instruments).
