Different Types of Polyurethane Coating Wheels

Polyurethane wheels occupy an important market with its unique characteristics and application scenarios, including TPU wheels, CPU wheels and PUE wheels, etc., each has advantages such as ground protection, friction resistance, UV resistance, etc., suitable for different occasions, improve work efficiency.

When discussing different types of polyurethane wheels, we have to mention their unique characteristics and application scenarios. As a high-performance material, polyurethane occupies an important position in the field of wheel manufacturing due to its excellent physical and chemical properties.

First, let's look at polyurethane (TPU) wheels. This type of wheel uses polypropylene or nylon as the wheel core, and a polyurethane wheel surface is formed on the outer edge of the wheel core through secondary injection molding technology. TPU wheels not only have the characteristics of protecting the ground, absorbing vibrations, leaving no marks, and not staining, but also have excellent friction resistance and corrosion resistance, and can roll easily on a variety of surfaces. In addition, its color can be modulated according to needs to meet the needs of different occasions. However, it is worth noting that the load-bearing capacity of TPU wheels will be reduced in high temperature environments.

Next is the cast polyurethane (CPU) elastomer wheel. This wheel uses an iron or aluminum core as the wheel core, and a thermosetting polyurethane elastomer formed by chemical reaction, which forms the wheel surface after curing at high temperature. CPU wheels also have the advantages of protecting the ground, no marks, no staining, and are UV-resistant and friction-resistant, making them very suitable for occasions that require high operating comfort. However, it is not resistant to hot water, water vapor, etc., so caution is required when using it in specific environments.

Let's talk about another type of cast polyurethane (CPU) wheel. This wheel is also based on thermosetting polyurethane elastomer formed by chemical reaction, and has similar advantages to the above-mentioned CPU wheel, such as ground protection and friction resistance. It is particularly worth mentioning that it has very low permanent deformation, low rolling resistance, and can withstand dynamic loads during high-speed operation, making it very suitable for use in high-speed occasions.

Finally, let's take a look at the polyurethane foam (PUE) wheel. This wheel has a unique microporous structure, low density, light weight, easy deformation and other characteristics. It also has many excellent properties such as high load-bearing capacity, high elasticity, and folding resistance. These characteristics of the PUE wheel make it an ideal choice for caster materials. Whether it is sound absorption, energy absorption or shock absorption, it can show its unique advantages.

In general, polyurethane wheels are widely used in various fields due to their excellent performance and diverse types. From TPU wheels that protect the ground and absorb vibrations, to CPU wheels that are UV-resistant and friction-resistant, to PUE wheels that are low in density and light in weight, each type of polyurethane wheel plays an indispensable role in its respective field. Choosing a polyurethane wheel that suits your needs can not only improve work efficiency, but also bring a more comfortable and safe experience.
