Introduction of PU

Polyurethane (PU) is a versatile and widely used polymer known for its flexibility, durability, and wide range of applications. It is a type of polymer formed through the reaction of isocyanates with polyols, resulting in a material with varying properties that can be tailored to meet specific requirements. PU can be found in both rigid and flexible forms, making it suitable for an extensive array of industries and applications.
