Forms of foam used in making mattresses

Latex, polyurethane, memory foam, gel foam and some patented foams are the most common forms of foam used to make mattresses, which are typically a variation of one or more of the ones we have noted. Here is an overview of each of these various types of foam along with the characteristics that make them ideal for sleeping on.

Latex Foams

 

Latex is a substance that is normal. A milky white sap originating from some varieties of trees is the raw material used for latex foam. It is probably the 'greenest' form of foam with a carbon footprint lower than other foam forms. Basically, there are two kinds of latex foam, known as Dunlop and Talalay latex.

Talalay Latex Process

The Talalay mechanism is different. It utilizes more energy to generate what is generally referred to as latex from Talalay. The beginning of the procedure is comparable to that of the Dunlop system. The mold is not completely filled with the foamy latex mixture in this situation, however, but it does include the heated rods. A vacuum pump is used after sealing the mold to extract air and other gases and to make the foam's composition evener. To fill the mold, the vacuum also extends the foam.

CO2 gas (carbon dioxide) is pushed into the forming foam as this takes place, allowing it to form a gel shape. One of these is that the gel temperature is increased to 220F, which encourages latex vulcanization, i.e., it becomes solid. As with Dunlop latex, the foam is then cleaned and dried. Finally, to avoid further reaction and expansion, it is frozen.

Dunlop Latex Process

The liquid soap is combined with sulfur and a catalyst, usually zinc oxide, in the Dunlop process. In the foam (just like whipping cream), the liquid mixture is whipped up and then poured into a mold. There are heated rods in the mold which push down into the mixture's body. These ensure the heating and removal of air pockets even during the next step.

The mold is sealed and then passed into a vulcanization oven known as an oven. When the particles chemically cross-link with the Sulphur, the latex is hardened. To remove any unused materials, the foam is cleaned. This washing stage ensures that over the longer term, the foam does not react further and loses its elasticity. The foam then undergoes a drying process to arrive at the finished product.

Difference Between Dunlop and Talalay Latex

There are differences between these two types of latex. Obviously, otherwise, why use the two types!

 Bounce: There's more bounce in Talalay foam than in Dunlop foam. For young couples, a Talalay foam mattress could therefore be better.

 Comfort: Talalay foam is less rigid than Dunlop latex, which means lying on it can be smoother than a latex mattress from Dunlop. Much depends on the manufacturer, though, and you can sleep very comfortably Dunlop foam mattresses, all depending on your personal 'comfortable' concept.

 Energy Efficiency: The Dunlop latex wins when energy conservation is important to you, normally because the process is easier than the Talalay process and uses less energy.
