Polyurethane Wikipedia

Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyol.Since polyurethanes contain two types of
