How silent casters work?

June 23, 2022

Why are trolley wheels and trolley wheels noisy and smelly when pushed. Why are the casters used in hospitals and hotels not as loud and smelly when they rub against the ground? It is proved that they use silent casters.

Silent casters use environmentally friendly thermoplastic elastomer TPE as the caster shell material.  What is TPE material? TPE material has the advantages of high elasticity, high strength, high resilience, temperature resistance from 50℃ to 115℃, excellent anti-slip and damping properties, softness and comfort better than rubber, etc. TPE material does not add phthalate plasticizers or sulfur, DCP and other toxic cross-linking agents in the production process, TPE materials have a more flexible molecular chain structure, TPE has small friction coefficient with the ground, and almost no sound when rubbing with the ground. It leaves no trace on the floor and does not damage the floor.

At the same time, due to the large coefficient of friction between the surface of the silent caster and the ground, the contact area is large and often difficult to push at high loads. This is the reason why silent casters are popular in the life industry,but also the reason why they are less used in industrial production.


With the improvement of living standards, people's requirements for the use of casters are getting higher and higher, and the silent and environmentally friendly TPR/TPE casters have become the best choice in the market.
