Which is better to use tpu or rubber in a universal wheel?

I. TPU

TPU is thermoplastic polyurethane, which has a wide range of applications due to its superior physical and chemical properties and mechanical properties. In terms of universal wheel, TPU’s durability and resistance to abrasion make the majority of manufacturers very keen on this material. Its advantages and disadvantages are as follows:

Advantages:

Abrasion resistance: TPU has excellent resistance to friction and is therefore able to keep its structure and properties stable over time.
Impact resistance: TPU has good resistance to impact and therefore protects the internal structure from damage caused by external forces during transportation.
Chemical resistance: TPU can resist the erosion of a variety of chemical substances, thus ensuring its long-term performance stability.
Environmentally friendly: TPU is recyclable and meets environmental requirements.
Disadvantages:

Cost: Compared to some other materials, TPU may cost more.
Temperature Resistance: Although TPU performs well over a wide range of temperatures, its performance may deteriorate under extreme heat.

II. Rubber

Rubber is an elastic material, made from natural or synthetic polymers. Rubber is also widely used in the manufacture of universal wheels.

Pros:

PRICE: Rubber is relatively less expensive and more cost effective.
Elasticity: the elasticity of rubber makes it an ideal material for absorbing shock and vibration.
Disadvantages:

ABRASION RESISTANCE: Rubber has relatively poor abrasion resistance and therefore may need to be replaced more frequently.
Chemical resistance: rubber is not as chemically resistant as TPU and may be more susceptible to chemical attack.
High temperature resistance: Like TPU, rubber may have reduced performance at extreme temperatures.

There are several factors to consider when choosing a material to be used in the manufacture of a universal wheel, including cost, durability, abrasion resistance, impact resistance and environmental friendliness. Depending on these factors, TPU shows superiority in many areas, so it may be a better choice than rubber for many applications.
