Polyurethane is mechanically bonded to a high density polypropylene core in this Urethane on Polypropylene Wheel. This mechanical bond eliminates bond separation due to wet conditions. The combination of both materials provides for a long lasting, long wearing industrial wheel that is impervious to water (including salt water), resistant to oils, grease, most solvents and chemicals. The polyurethane tread is non-marking and offers a quiet ride, floor protection and excellent capacity ratings. These polyurethane wheels have a slight crown so that they maneuver very well. The Urethane on Polypropylene Wheel provides a smooth ride over rough surfaces. Urethane on Polypropylene Wheels are very popular, attractive, lightweight and extremely durable wheels used in countless
applications.
