Why do casters have polyurethane wheels?

Why do casters have polyurethane wheels?

polyurethane is short for spring glue, short for polyurethane or isocyanate polymer, and its English name is polyurethane. It is a kind of polymer material, which is an elastic body between plastic and rubber. Polyurethane is a new kind of organic polymer material, known as “the fifth largest plastic”, because of its excellent performance is widely used in many fields of national economy. Our products are applied in light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation and so on.

Polyurethane caster universal wheel elastomer has:

1, high mechanical strength and oxidation stability;

2, with high flexibility and resilience, low pressure, strong impact, tear resistance, radiation resistance, high bearing capacity and shock absorption buffer;

3, with excellent oil resistance, solvent resistance, water resistance and fire resistance.

4, good wear resistance

In addition, polyurethane wheel has excellent sound-absorbing characteristics, caster in the process of movement will not produce noise, can achieve the silent effect.

These characteristics of PU wheels are very suitable for casters.

Polyurethane Elastomers (PU Elastomers)

Cast polyurethane elastomer (CPU) is one of the most widely used polyurethane elastomers with the largest output.

Thermoplastic polyurethane elastomer (TPU) – Thermoplastic polyurethane elastomer accounts for about 25% of the total amount of polyurethane elastomer;

Mixed polyurethane elastomer (MPU) – accounting for about 10% of the total polyurethane elastomer.
