Why do TPE caster wheel replace PVC caster wheel?

Usually the ordinary TPE caster materials we use, because the TPE caster material itself has anti-slip properties, so the wear resistance of the TPU material will be better, but the TPE caster material used for the caster wheel increases with the load-bearing requirements, in the TPE caster wheel material Add appropriate slip agent to improve the slipperiness of its surface, reduce the surface friction coefficient of TPE caster wheel materials, thus reduce friction heat and increase friction loss. So what are the specific advantages of wear-resistant TPE caster wheel materials?

1. Bearing capacity


The load-bearing capacity of TPE materials is generally not very high. At present, the maximum load-bearing capacity of TPE as the outer covering in the domestic market is 300kg. Because the TPE material itself is relatively soft and rigid, it is formed by bonding with the frame, so a large amount of heat will be generated when the load moves, which will accelerate the deformation of the material, which will cause the caster wheel frame and rubber to fall off or crack. The load-bearing capacity of the caster is up to 300kg.

2. The material selection methods of different skeleton materials are different


The skeleton of the caster wheel is generally PP, reinforced PP, nylon, etc. Generally, the caster with a lower load chooses PP as the skeleton, and some low-end materials even use recycled PP as the skeleton. This kind of skeleton is relatively brittle, and some other materials or It is degraded, so the adhesion performance of TPE is higher. If it is reinforced PP, it is generally reinforced by adding glass fiber, so there are higher requirements for the bonding performance of the material. Ordinary original package PP generally uses homopolymer TPE caster wheel material.

3. Wear resistance


Ordinary TPE materials, because of their anti-slip properties, will have better wear resistance than other materials. However, with the increase in load-bearing requirements of TPE materials for caster wheel, TPE medical caster materials will add appropriate slip agents to improve surface cooling Slip, reduce the surface friction coefficient of the material to reduce friction heat and increase friction loss.

4. Where is the advantage of TPE?


The replacement of PVC with TPE caster wheel is an inevitable trend. Since more and more countries, especially Europe and the United States, explicitly prohibit the use of PVC caster wheel, the export of caster processing factories have to face this reality. Of course, you may also choose TPU However, the inherent defects of TPU caster wheel make more manufacturers prefer TPE. With the maturity of TPE technology, everyone's understanding of TPE will be more and more in-depth, so it is more and more widely used.
