Popular science information about PU
PU (Polyurethane) is a versatile and highly adaptable polymer that is widely used in various industries. It is formed through the reaction of diisocyanates with polyols, resulting in a wide range of polyurethane materials with different properties and applications.
PU is known for its excellent abrasion resistance. It can withstand repeated friction and wear, making it suitable for applications that require durability, such as in industrial machinery components, conveyor belts, and coatings for floors and surfaces.
PU is a lightweight material, which makes it suitable for applications where weight reduction is desired. It has a low density compared to other materials, such as metals and glass, while still providing comparable strength and performance. This property makes PU a popular choice for applications that require both strength and lightweight characteristics, such as in aerospace components and sports equipment.
PU is also known for its excellent thermal insulation properties. It has a low thermal conductivity, making it an effective insulator against heat and cold. This property makes PU suitable for applications that require thermal insulation, such as in building insulation, refrigeration, and thermal packaging.
