* High density, good wear resistance, relatively low elasticity

* The lower the density, the higher the elasticity.

PVC wheels are made of plastic raw materials.The density and elasticity are immutable.

PU wheels are relatively soft, elastic and wear-resistant.

PVC wheels are relatively hard and have good anti-aging properties, but they are not wear-resistant ...

PU is a better material, but the price is more expensive than PVC wheels.

Here is a simple way to distinguish between PU wheels and PVC wheels. If you use fire, the PU casters wheels taste lighter. PVC casters will have black smoke and bad smell
