Talalay process

The Talalay process is a method of producing molded pieces of latex foam rubber. A liquid latex rubber base is introduced to a closed mold that has been vacuumed of air. The mold is then frozen to stabilize the cell structure. Carbon dioxide gas is introduced and the mold is heated to cure the rubber. Leon, Joseph and Anselm Talalay developed the "Talalay" process at various commercial entities. B.F. Goodrich in Shelton, Connecticut, Dunlopillo in Pannal, Harrogate, UK, and Vita Talalay in Maastricht, Netherlands, made this process commercially practical in the late 1940s. The first Talalay production plants were built in England, Canada and the United States.
