Polyurethane (/ ˌpɒliˈjʊərəˌθeɪn, - jʊəˈrɛθeɪn /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane term does not refer to the single type of polymer but a group of polymers.

Urethane, also called ethyl carbamate is the ethyl ester of carbamic acid with the chemical formula C 3 H 7 NO 2. It has a broad spectrum of biological activities and is a known multisite carcinogen capable of inducing tumours in various animal species.
