- Polyurethane - Wikipedia
Polyurethane ( ˌpɒliˈjʊərəˌθeɪn, - jʊəˈrɛθeɪn ; [1] often abbreviated PUR and PU) is 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

Polyurethane is a typical thermoset polymer compound characterized by durability, flexibility, toughness, and resistance to abrasion, acids alkalis, solvents, and weathering It is formed through a covalent polymerization reaction between a polyol group and an isocyanate group
- How polyurethane is made - material, production process, making . . .
Polyurethanes are linear polymers that have a molecular backbone containing carbamate groups (-NHCO2) These groups, called urethane, are produced through a chemical reaction between a diisocyanate and a polyol First developed in late 1930s, polyurethanes are some of the most versatile polymers
