PU, or polyurethane, is a versatile material commonly used in various products, from furniture to insulation. It can be found in flexible forms, like foam cushions, or rigid forms, such as hard plastics. This adaptability makes PU popular in industries like automotive, construction, and footwear. One of the key benefits of PU is its durability and resistance to wear and tear. For example, PU foam is often used in mattresses and pillows because it provides excellent support and comfort. Additionally, PU coatings are used to protect surfaces, making them more resistant to scratches and chemicals, enhancing their longevity.
