Answer) Urethane is a crystalline compound that is the ethyl ester of carbamic acid, and in most cases, it is used as a solvent, and in medicine, it is used as an antineoplastic agent. Talking about its applications, we came to find out that urethane is much more superior to metals due to its toughness. The urethane elastomers are the element that can easily replace metals in pulley wheels and Conveyor rollers, ball-bearing, cartwheels, and rollers as well. Speaking of load-bearing capacity, the urethane performs well and can easily withstand high load without breaking. Its high durability allows it to be used in the manufacturing of materials and parts which need to stand the test of time. Moreover, in metal, you can hear the sound when the friction is in the play. But that’s not the case with urethane.
