Polyurethane is primarily used as a matching tank in planetary ball mills, a mixing tank in roller ball mills, and in applications such as polyurethane synthetic leather, polyurethane foam, polyurethane coatings, polyurethane adhesives, polyurethane rubber (elastomers), and polyurethane fibers. Additionally, polyurethane is employed in civil engineering, geological drilling, mining, and petroleum engineering for water blocking, stabilizing buildings or roadbeds. As a paving material, it is used for sports track surfaces, indoor flooring in buildings, and more.
