Polyurethane

Polyurethane is a versatile polymer composed of organic units joined by urethane (carbamate) links. It is created through a chemical reaction between a polyol (a molecule with multiple hydroxyl groups) and a diisocyanate or polyisocyanate.

Depending on its formulation, polyurethane can be flexible, rigid, soft, or hard, making it one of the most adaptable plastics in modern manufacturing.
