Polyurethane is a class of polymers composed of organic units joined by carbamate (urethane) links. It is often abbreviated as PU or PUR and is classified as a thermosetting polymer, meaning it does not melt upon heating2. Polyurethane is widely used for its durability and protective qualities, making it ideal for applications such as coatings for floors and furniture3. There are many types of polyurethanes, each made in slightly different ways, often involving the combination of diisocyanates and polyols4.
