Urethane on Poly wheel utilizes polyurethane mechanically bonded to a high-density polypropylene core. This mechanical bond eliminates bond separation due to wet conditions. Tread material is 95 Durometer Shore A and provides excellent rollability with a non-marking compound. It provides a smooth ride over rough surfaces. UPR is an excellent for wet applications and around caustic surfaces. Temperature range: -40 degrees F to 175 degrees F.
