The open timing belt is composed of thermoplastic polyurethane. It is highly abrasion-resistant and has small production tolerances. Steel wire cores ensure that it runs smoothly in applications involving high loads. In addition to polyurethane, nylon cloth is often added to the tooth surface and back for better operating characteristics.

The open timing belt is typically 25mm wide. The PU belt is available in several core materials, including kevlar. The PU belt is typically sold by the foot or can be customized. The PU belt functions similarly to a ring. The main difference between the two is that the PU material is transparent instead of black.
