Polyurethane (PU) is the generic name for polymers possessing a urethane bond. A urethane bond is formed via an additional reaction between an isocyanate group and a compound possessing active hydrogen, such as a hydroxyl group.
Isocyanate groups are extremely reactive and for this reason, this reaction proceeds without the addition of heat. A major feature is that, once reacted, an extremely stable structure is adopted. In other words, the external appearance of polyurethane takes on various forms, such as foamed products, films, elastomers, powders, liquids, and emulsions
