Polyurethane is a versatile polymer composed of organic units joined by carbamate (urethane) links. It can be formulated as a flexible or rigid material, depending on its chemical composition and processing. The properties of polyurethane can vary significantly based on the types of polyols and isocyanates used in its production.
