Urethane is any chemical compound produced by the reaction of an isocyanate and an alcohol according to the following formula:
R-N=C=O + H-O-Q →Although the reaction had been known for some decades, it was not until 1937 that Otto Bayer discovered how to make a useful plastic out of polyisocyanate and polyol.H / R-N \\ C=O / Q-O
Urethane technology was brought to America in 1953 by Jean-Pierre Abbat and Dr. Fritz Hartmann.
Polyurethane can be made in a variety of textures and hardnesses by varying the particular monomers used and adding other substances. It is used in adhesives, elastomers, foams, sealss, gaskets, condoms, and hard parts.
