Why do the wheels of trolley cases and trolleys make a lot of noise and smell when pushed? Why do the casters used in hospitals and hotels not make such a loud sound when they rub against the ground, nor do they smell that much? It turns out they used silent casters.
The silent caster uses an environmentally friendly thermoplastic elastomer TPE as the outer material of the caster. What material is TPE? TPE material has the high elasticity, high strength, high resilience of rubber, temperature resistance of 50~115℃, excellent anti-skid and shock absorption properties, and its softness and comfort are superior to rubber. TPE materials do not add phthalate plasticizers, sulfur, DCP and other toxic cross-linking agents during the production process, and TPE thermoplastic elastomer materials have a relatively flexible molecular chain structure and a relatively low friction coefficient in contact with the ground. It is small and makes almost no sound when it rubs against the ground. Leaves no marks on the floor and won't damage the baseboards. At the same time, the special styrene butadiene block structure of TPE material ensures that the material has high strength and wear resistance.
The large friction coefficient between the wheel surface of the silent caster and the ground and the large contact area often make it difficult to push when the load-bearing capacity is high. This is why silent casters are so popular in the lifestyle industry. However, it is less used in industrial production situations. If you have questions about choosing casters, please contact us.
