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.
- Polyurethane | Foam, Synthesis, Plastics | BritannicaPolyurethane, any of a class of synthetic resinous, fibrous, or elastomeric compounds belonging to the family of organic polymers made by the reaction of diisocyanates (organic compounds containing two functional groups of structure ―NCO) with other difunctional compounds such as glycols.
- Polyurethane: Definition, Properties, Types and Applications - Ruitai MouldPolyurethane is a versatile synthetic thermoset polymer. Commonly abbreviated as PUR and PU, it is known for its wide application in various industries and offers excellent properties such as strength, durability, flexibility, and thermal stability.
- All About Polyurethane - This Old HousePolyurethane is a synthetic resin used to protect and enhance the appearance of wood surfaces. It works by forming a hard, protective coating on the wood surface. This coating can range from a clear finish, which preserves the natural look of the wood, to a tinted finish that adds color and depth.
