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.
