Polyurethane is a polymer containing the urethane group. Polyurethanes find a wide variety of applications in many industries. In fact, mollifiable polymers (hydrophobic) like bitumen, polyvinyl acetate and polyurethane form a major class of soil conditioners. Polyurethane resins and the foams are also used as florists' mounting media or plant growth media.
