Polyurethane casters are high-quality casters made from polyurethane material. They are characterized by wear resistance, acid and alkali resistance, oil resistance, high strength, and good resilience. Polyurethane casters are widely used in light logistics equipment, trolleys, and other occasions, making them an excellent performance caster.

       1. Characteristics of Polyurethane Casters

       Polyurethane casters have good wear resistance, not only exhibiting excellent wear characteristics but also being less prone to wear. Therefore, they have a long lifespan and can be used for extended periods.

       They have good acid and alkali resistance, providing excellent resistance to acidic and alkaline substances. Therefore, polyurethane casters are widely used in the chemical and pharmaceutical industries, where acidic and alkaline substances are present.

       They have good oil resistance, able to withstand the corrosion of oil, chemicals, and various solvents, making them widely used in machinery manufacturing, automotive industry, and other fields.

       They possess high strength and hardness, capable of bearing large loads, and are therefore widely used in large equipment and heavy transport vehicles.

       They have good resilience, which can prevent adverse effects on products or equipment during transportation when encountering bumps.

       The appearance can be customized according to needs, satisfying both functional use and aesthetic appeal.

       2. Principles of Polyurethane Casters

       Polyurethane is a high molecular composite material with elasticity and resilience.

       The characteristics of wear resistance, oil resistance, and acid and alkali resistance in polyurethane casters are mainly produced by the interaction of two elemental units within the polyurethane molecules.

       In the ether-type polyurethane molecules, the ether units under the terminal hydrogen react with aliphatic dicarboxylic acids and other molecules to form a chain-like structure similar to carbohydrates, which has elasticity; polyurethane rubber molecules with this as the main chain exhibit better wear resistance and resilience than conventional rubber.

       In addition to the inherent advantages of the material, modern advanced laser micro-processing technology also provides significant support for enhancing the performance of polyurethane casters.

       Using laser micro-processing technology, the rough surfaces of polyurethane casters can undergo friction reduction and polishing treatments, utilizing laser quantum forces to drive various reactions and form micro-patterns on the surface, thereby reducing the friction coefficient and enhancing slip resistance, ultimately extending the lifespan of the casters.

       At the same time, laser micro-processing technology can also enhance the mechanical properties of polyurethane casters, such as fatigue strength, crack resistance, pressure resistance, and compressive strength, improving their stability in applications.

       In summary, polyurethane casters have characteristics such as wear resistance, acid and alkali resistance, oil resistance, and good resilience, effectively solving the problems of traditional casters. Additionally, utilizing modern advanced laser micro-processing technology can further enhance the performance of polyurethane casters, making them an ideal choice for various equipment and machinery.
