Polyurethanes are versatile materials made from a reaction between polyols and isocyanates. They can be found in various forms, including flexible foams, rigid foams, elastomers, and coatings. Due to their durability and resistance to wear, they are commonly used in furniture, insulation, and automotive parts. These materials can be tailored for specific applications by adjusting their chemical composition. Polyurethanes are also known for their ability to provide cushioning and support, making them popular in mattresses and sports equipment. Their adaptability and performance make them essential in many industries, including construction and consumer goods.
