As an engineering material, polyurethane has high wear resistance and can withstand large friction and pressure. Polyurethane is a polymer formed by the reaction of isocyanate and polyol, so its properties are affected by the type and proportion of the composition materials. Generally, the main components of polyurethane materials are polyether or polyester polyols and isocyanates.
Polyurethane materials have good wear resistance, mainly manifested in the following aspects: First, polyurethane has high density and strength, and can withstand large friction and pressure. Under heavy load, the surface of polyurethane materials has less scratch and wear. Second, polyurethane materials have a smooth surface and high hardness, which can effectively resist wear caused by friction and shear forces, and have a longer service life. Third, polyurethane materials have good elasticity and can self-recover, even under large wear or strong impact, they can maintain good wear resistance.
Therefore, polyurethane is widely used in various fields such as machinery, mining, construction, and transportation. Its excellent wear resistance performance has greatly improved the service life and production efficiency of various equipment and machinery, making it an ideal choice for many engineering applications.
