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.
==Product==
The Talalay process is an elaborate process that yields very controlled densities and product "feel". The formulation uses many of the same base components as the Dunlop formulation, but without gellation reagents. The result is marketed as a healthier alternative to petroleum-based foams since petroleum-based foams give off volatile organic compounds as they age. In the marketing of products such as beds that include "natural" latex foams created with the Talalay process, these products are sometimes characterised as 'organic' or as completely natural. However this claim may not be completely true since unspecified curing agents are used in the Talalay process and ammonia is commonly used to stabilize liquid rubber.
