1.Urethane plates are fracture resistant, harder wearing than the typical rubber bumper plate, easier to clean and have a consistent dead bounce due to its high durometer rating.

2.Urethane compresses better than rubber but flexes less. This means that they have the resilience of a bumper but don't wobble or flex as much when dropped, particularly for thinner plates.

3. Urethane plates are resilient in design, and remain aesthetically appealing over time.
