SpletUrethane is a type of resin that’s used to make a range of plastic items. It’s end-use is highly versatile; you can create both flexible items that are almost rubbery in texture, and very rigid plastics. Urethane casting’s in the manufacture of short-run, low-volume products such as movie props or bespoke models. Otto Bayer and his coworkers at IG Farben in Leverkusen, Germany, first made polyurethanes in 1937. The new polymers had some advantages over existing plastics that were made by polymerizing olefins or by polycondensation, and were not covered by patents obtained by Wallace Carothers on polyesters. Early work focused on the production of fibers and flexible foams and PUs were applied on a limited scale as aircraft coating during World War II. Polyisocyanates beca…
