The term “silent universal wheel” is not specific enough to determine the exact material used. However, in general, many wheels designed for silent operation or reduced noise are made using materials such as rubber or specialized polymers.

Rubber wheels are commonly used for their noise-dampening properties. They provide good traction, absorb shock, and are often used in applications where quiet operation is desired, such as office chairs, trolleys, or certain types of industrial equipment.

Alternatively, there are wheels made of specialized polymers that are designed to minimize noise. These polymers are engineered to have low rolling resistance and provide smooth and silent movement. They may incorporate additives or coatings to reduce friction and noise generation.

It’s important to note that different manufacturers may use proprietary materials or combinations of materials to achieve silent operation for their specific wheel designs. Therefore, the exact composition of the material used in a silent universal wheel can vary depending on the manufacturer and the intended application.

The general silent universal wheel uses PVC material in the outer layer, and the better quality is to use TPE material.As a luggage manufacturer, we will also recommend the corresponding universal wheel according to the needs of customers
