Polyurethane formulations cover an extremely wide range of stiffness, hardness, and densities. These materials include: * Low-density flexible foam used in upholstery and bedding * Low-density rigid foam used for thermal insulation and RTM cores * Soft solid elastomers used for gel pads and print rollers * Hard solid plastics used as electronic instrument bezels and structural parts Polyurethanes are 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, high performance adhesives and sealants, Spandex fibers, seals, gaskets, carpet underlay, and hard plastic parts. source: http://en.wikipedia.org/wiki/Polyurethane

∙ 13y agoPlastic is a very generalized term for polymers that can mean either a thermosetting or a thermoplastic Plastic. There is Polyethylene Terephthalate (PETE), Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polypropylene (PPE), Vinyl (V), Styrofoam (Polystyrene), on the thermoplastic side and bakelite on the thermosetting side. Polyurethane, however, is an elastomer.
