What is the difference between polyurethane wheels and rubber wheels?

Casters can be divided into many types according to the material used. Among them, polyurethane wheels and rubber wheels are relatively similar, and sometimes it is difficult to distinguish them based on their appearance.

Overall, polyurethane wheels are better. There is now a trend of polyurethane wheels replacing rubber wheels. Polyurethane casters have some features that are superior to rubber casters, which are specifically reflected in the following:

1. Service life: Polyurethane casters usually have a longer service life and are more wear-resistant, which also reduces the cost of use.

2. Load-bearing capacity: The load-bearing capacity of polyurethane casters is much greater than that of rubber casters, which is several times the load-bearing capacity of rubber casters, because polyurethane casters have better pit growth and tear resistance.

3. Environmental protection: Because polyurethane is a man-made material and does not require a large amount of rubber raw materials, it is more environmentally friendly.

4. Rolling resistance: Because the chemical structure of polyurethane material determines that it has smaller rolling resistance than rubber, the added thrust is smaller and more labor-saving.
Although polyurethane wheels are superior to rubber wheels in many aspects, rubber wheels also have their own advantages, so they have not been completely replaced. For example, rubber casters are softer, more comfortable, and have better buffering capabilities.
