Polyurethane (PUR or PU) is a versatile polymer composed of organic units joined by carbamate (urethane) links. It can be manufactured in various forms, including flexible and rigid foams, elastomers, coatings, adhesives, and sealants. Known for its durability, flexibility, and resistance to abrasion, chemicals, and weathering, polyurethane is widely used in furniture, automotive parts, insulation materials, footwear, and industrial applications. Its properties can be tailored during production, making it suitable for various uses.
