What's the reason of use polyurethane-coated wheels in heavy industrial applications?

The following are the most convincing reasons for polyurethane coated rubber wheels:
1. Noise reduction:
Compared with harder wheels (such as steel or cast iron), polyurethane wheels are quiet in operation and are therefore a popular choice in industrial applications. Polyurethane acts as a shock absorber and helps cushion the driving process. It can also absorb bumps caused by uneven terrain. When OSHA regulations come into effect, using polyurethane instead of steel or cast iron wheels can significantly reduce noise levels and help protect employees' hearing.
2. Carrying capacity:
Compared with rubber, polyurethane tires often use their load-bearing capacity. Polyurethane wheels can provide greater load-bearing capacity while still providing the advantages of rubber treads, such as reducing noise, absorbing impact and protecting the floor.
3. Floor protection:
Polyurethane tires dominate in applications where the protection of floors is vital. Compared to harder wheel materials (such as nylon), polyurethane deforms and creates a larger footprint. The larger surface area helps reduce stress concentration on the floor and keeps the floor in a better shape for a long time.
For factories where floors are expensive and critical to your operation, polyurethane tires may be the first choice.
4. Better grip and traction:
Another benefit of polyurethane wheels in industrial applications is the friction coefficient of the material. This value describes the ratio of the friction between two objects to the force that presses them together. Rough surfaces tend to have higher effective values, while smooth surfaces have lower effective values ​​because they will rub together when pressed together. Polyurethane is often an easy-to-grip material, so its higher coefficient of friction can help prevent trailer dragging. For harder wheel materials, sliding is an important consideration. Polyurethane can also provide excellent traction to the drive wheels and help reduce the amount of load on the wheels to achieve the required driving force.
5. Corrosion resistance:
There are many different types of polyurethanes that have different resistance to specific environments or conditions. For example, chemicals, solvents and even water. (We have listed some different types below). In a humid environment, certain polyurethanes will not decompose or corrode in the presence of water. In the event of chemical exposure problems, other types of polyurethane can be used to extend the life of the wheel.
