Foam rubber was first produced in 1929 by Dunlop Rubber researcher chemists E. A. Murphy and Eric Owen using whipped latex. In 1937 isocyanate based materials were first used for the formation of foam rubbers, after World War II styrene-butadiene rubber replaced many natural types of foam. Foam rubbers have been used commercially for a wide range of applications since around the 1940s.
Polyether polyurethane rubber was discovered and patented in the 1950s by Charles C. Price. Currently, polyurethane-based foams make up over 90%, by weight, of the entire market for polyurethanes. The largest amount of polyurethane is used by these industries: construction, transportation, home furniture, noise and vibration reduction, and carpet. Construction uses 27% of polyurethane, and transportation uses 21%. Flexible foam is the leading material usage at 44% total volume, and rigid foam material at 28% of the United States market.
