Polyurethane Foam- C27H36N2O10

What is Polyurethane Foam?

Polyurethane foam is a linear polymer composed of organic units joined by links of carbamate. The chemical formula is C27H36N2O10. Polyurethane is another synthetic resin-type varnish. Polyurethane foam are formulated in different ways for different uses. A urethane is a carbonyl containing functional group in which the carbonyl carbon is bonded to both an -OR group and an -NR2 group. A polyurethane is formed by reacting a hydroxyl terminated polyether or polyester with an isocyanate.
