|Latex Green is the Premier “Dunlop” processed latex manufacturer in the world. They offer both 100% natural and now
Dunlop foam mattress cores and mattress toppers made with USDA Certified Organic Latex. Latex Mattress Company now offers latex mattresses made with organic latex in the latex cores and toppers from Latex Green.
|We use the “Dunlop foam” process, with only Sri Lankan high Quality “Natural Latex”.|
Dunlop Process Overview
The Dunlop process is the most common method of producing mattresses and other products made from natural latex. In this process, the serum is collected from rubber trees, then frothed in a centrifuge. The material is then poured into a mold and baked at a low temperature. As the latex bakes and begins to firm, particles and sediments tend to fall and settle at the bottom of the mold. Because of this, products made through the Dunlop process often have one side – the bottom – which is somewhat firmer.
Around the world, the Dunlop process is the most common method of latex production. Latex products made using the Dunlop process are typically more dense than those made using the Talalay process.
Talalay vs. Dunlop – Which is Better?
The Talalay process is a highly controlled, sophisticated latex manufacturing process that produces the highest quality, most consistent latex available in the world. The Dunlop process is the most commonly used production method globally. It creates a firmer product that is most often used as a base core component.
The major difference between the two processes is what happens in the mold just prior to the initial latex curing stage. In the Talalay process, only a small amount of latex compound is poured into the mold. Air is extracted to perfectly distribute the foamed liquid inside the mold and to create a consistent round, open cell structure. The mattress core is flash frozen to lock the cell structure in place and to prevent the particles from settling.
In the Dunlop latex process, 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”. This process produces a heavier product. gravity takes over settling the particles to create a more dense product than than the talalay process. Talalay latex is available in a much wider firmness range so it can provide enhanced comfort choice for consumers around the the globe.
Over the last 10 years the Dunlop process has been improved drastically and now the debate is on over which is actually better, the Talalay latex or the Dunlop foam.
