Polyurethane wheels are commonly seen in commercial, industrial and food services fields. Their durability, resiliency and the ability to provide a smooth ride on many surfaces make them popular by people. Some industrial polyurethane wheels can resist salt water, chemicals, oil and grease. They handle heavy load capacities and can operate in harsh environments. Typically, many manufacturers offer polyurethane wheel and caster assemblies for installation on industrial and commercial equipment that move heavy loads. But modern polyurethane wheels also get through a hard time.
Since the 60th of last century there had been some studies about polyurethane elastomer's application in polyurethane wheels. There was once a rush of researching on the polyurethane wheels all over the world, especially in the western countries. But in the end of the last century, the development of the polyurethane wheels fell into slump. Inner high temperature produced in the polyurethane elastomer and poor ability of resisting high temperature are the main factors that control the high speed usage of the polyurethane wheels.
In the first of the 21th century, there have been another studying rush of thepolyurethane wheels and a great breakthrough of the high produced heat problem has been made. This research result contributes a lot to the polyurethane wheels application.
