Dunlop process: The traditional Dunlop process has been uesd in latex foam manufacture since 1929. In the Dunlop Process air is beaten into liquid latex to foam; minute amounts of fluories used to gel the foam in a mould. The moulds are then steamed to vulcanize to cure the foam. Subsequent to stripping, it goes through washing washing and drying. The molds are filled to the rim, air is not extracted, and there is no freeze stage. Therefore, the latex cell structure is less"airy".
Talalay process: In the Talalay process, only a small amount of latex compound is poured into the mold, then foamed latex is expanded by vacuum to fill the mould and freeze it to capture the bubble structure at -30°C, treating it with gaseous carbon dioxide and vulcanized at 110°C. Then it goes through the same process of stripping, washing and drying. Talalay latex is available in a much wider firmness range so it can provide enhanced comfort choice for consumers around the globe.
