Thermo Plastic Wheels are also known as TPR Wheels, Thermo Wheels, and Thermo Plastic Rubber wheels. These wheels are softer than a standard polyurethane wheel you would normally use. With a 75 Shore A Durometer (Softness of Wheel); these are exclusivley made to roll over debris, gaps, cracks, obstacles with ease. The softer tire allows it to grip and roll-over obstacles opposed to harder wheels that will just push or get stuck while rolling. These gray soft rubber wheels are non-marring, non marking, quiet, absorb shock, vibrations, and protect equipment and floors and many floor surfaces. The only setback to this type of wheel is the roll-ability is slightly less compared to a harder wheel since the thermo plastic rubber wheel provides more cushion to protect expensive cargo. Thermo Rubber wheels are not meant to have heavy loads sitting in one spot for long periods of time or they could potentially develop flat spots in the wheels and it will make them harder to roll. The tread is chemically bonded with a industrial glue, if these are exposed to extremely harsh chemicals or high speeds and heat can affect the quality of the glue and could possibly compromise the tread. These wheels have been around for a very long time for a reason, and that is to protect cargo, floors, and provide an extremely quiet ride. If you have any applications please feel free to contact us. Common Thermo Rubber Wheel Applications: Applications include: Computer racks, conveyor stands, medical & laboratory equipment, printers, copiers, modular framing enclosures, electronic enclosures, manufacturing machinery and automation enclosures.
