Understanding Polyurethane Foam

Polyurethane foam is a type of polymer made up of organic components joined by urethane links. Its chemical structure is represented as C₂₇H₃₆N₂O₁₀. This synthetic resin is versatile due to its various formulations for different applications. The urethane in polyurethane is a carbonyl-containing functional group where the carbonyl carbon is attached to both an -OR group and an -NR₂ group. The creation of polyurethane involves a chemical reaction between a hydroxyl-terminated polyether or polyester and an isocyanate. Polyurethane foam is also known as Ethylene glycol copolymer.
