WebPolyurethane, often abbreviated to PU or PUR, is an organic polymer that features many organic units linked via urethane molecules. Most polyurethanes do not melt upon heating and can, therefore, be classified as thermosetting polymers. However, it can be noted that some specific types of polyurethanes exhibit thermoplastic properties and can be melted BAN72PuhjHlP Polyurethane refers to a class of polymersposed of organic units joined by carbamate links. In contrast to othermon polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials.
