The difference between the polyurethane material and nylon used to make this wheel on 150mm Crowned Polyurethane Wheel

Polyurethane is made by polymerization of isocyanate (monomer) and hydroxyl compound. Because it contains strong urethane groups, it is insoluble in insoluble groups and has good oil resistance, toughness, abrasion resistance, aging resistance, and adhesion. Different raw materials can be used to produce materials suitable for a wide temperature range (-50～150℃), including elastomers, thermoplastic resins, and thermosetting resins. It is not resistant to hydrolysis at high temperatures, nor is it resistant to alkaline media.

Therefore, in general, nylon casters have higher hardness and are more wear-resistant. It is better in terms of weight-bearing. Polyurethane casters are softer, and their strength is lower than that of nylon casters, but the noise reduction effect is much better and the overall capacity is higher.
