There are two main methods of processing latex – the Dunlop and the Talalay process. We use the Dunlop process, which has been practised since the late 1920s. First, the sap is extracted from the rubber tree, then put into a centrifuge machine and whipped into a froth. The froth is then placed into a mould with a small amount of gelling agent (sodium silicofluoride), covered, and steam baked. The latex is then washed and rinsed which removes any residue left over from the gelling and baking process, as well as removing most VOC’s.
The Talalay Latex process has a few more steps than the Dunlop Latex process. Once the sap is in the mould with the gelling agent, it is placed in a vacuum chamber, and air is extracted. It is then flash frozen, and chemicals used to stabilise it. After this the mould is baked before it is washed and then rinsed alike to the Dunlop method.
It is important to note that although you may find 100% Natural Talalay Latex on the market, it is not possible to create certified Organic Talalay Latex. Consequently, the Dunlop Latex process is the only way to produce 100% Certified Organic Latex internationally. As our first priority is to create a natural and clean product, we choose to use the Dunlop process.
