CasterHQ's Thermo Plastic Rubber wheels are extremely high quality non-marking gray thermo-plastic engineered rubber tread bonded to an industrial Polyolefin (plastic) core used in many applications such as food service, hospitals, laboratories, and many institutional applications and industries. 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 exclusively made to easily roll over debris, gaps, cracks, and obstacles. The softer tire allows it to grip and roll over obstacles as opposed to harder wheels that will just push or get stuck while rolling.

These soft gray rubber wheels are non-marring, non marking, quiet, absorb shock and vibrations, and protect equipment, 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, or they could potentially develop flat spots in the wheels, making them harder to roll. The tread is chemically bonded with 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 long time: to protect cargo and floors and provide an extremely quiet ride. If you have any applications, please feel free to contact us.
