). Urethane will not abrade particles which can contaminate critical components in your drive, your product or your environment. Relatively hard urethanes still maintain good flexibility without the use of a plasticizer. This equates to a stiffer overall system versus using a rubber belt such as neoprene. Urethanes can maintain this flexibility over a significant temperature range (-30°C to 80°C with short term to 120°C). Urethane also does not harden and degrade with age to the degree that neoprene does. Urethanes are highly elastic and tough which helps them to absorb shock and impact.
