Urethane

Definition

Urethane, also known as ethyl carbamate, is a compound formed from the reaction between an alcohol and an isocyanate group as part of the step-growth polymerization process. It is a key building block in the production of polyurethanes, which are versatile synthetic polymers used in a wide range of applications from foams to elastomers.
