Polyurethane typically lasts longer than rubber, especially in applications where it’s constantly stretched
or otherwise exposed to stress. Both rubber and polyurethane are elastic and flexible. Polyurethane,
however, can withstand significantly more cycles of repeated stretching than its counterpart because of
its carbamate links. When used in the production of automotive components, polyurethane can often
last for the lifespan of the vehicle. Rubber is also long-lasting, but it’s prone to degradation from
repeated stretching or stress
