For the production of latex mattresses, there are two processes: the Dunlop foam impact process and the more expensive Talalay blowing process. The largest part of the foam rubber on the market is produced by the favorable Dunlop process. Here, the vulcanizable latex compound with foaming agents and shifted to a stable foam pitched, of the 8 - to 12-fold volume of output has substance. Then he comes into the closable forms and is cured . Is evaluated as negative, that must be added in this process and that some chemicals after washing and drying shrinkage of the material occurs by about five percent.
The Talalay process is more complicated and costly propellant. The advantage is that no additional chemicals must be used and occurring no shrinkage of the vulcanizate. With the help of oxygen, the latex on the 10 - to 14-fold inflated. This very fine-pored foam is then poured into the mold and continue treatment. Another Talalay process uses vacuum.
Since the Talalay process is very expensive, it is rather used for mattresses in the premium sector and particularly for soft and sumptuous mattresses.Natural Latex Mattress - Production
In the "production" is the most important process of vulcanization. So you think the process of networking and fixation of the latex molecules. In this method, the chemical-technical viscoelastic converts raw latex rubber foam to be highly elastic. This requires heat, sulfur and vulcanization accelerators (Dithiocarbomate) or activators (for example zinc oxide). In order for the vulcanization of rubber in the interior of the body, the raw latex is poured into molds, which have many small pins. Through these hot steam or hot water is passed so that the vulcanization proceeds evenly. This is called latex from the pin. It is also possible that the mattresses have cavities - the so-called caverns.
Natural Latex Mattress - Advantages and Disadvantages
Natural latex foam has high elasticity and tensile strength combined with low temperature flexibility and good dynamic properties. Added to this is an acceptable resistance to abrasion and aging. The union of all these properties make natural latex is still essential, though there are synthetic latex variations that exceed natural latex in individual properties.
Unlike most synthetic latex is natural rubber latex variants but not UV, heat and oxidation resistant. Therefore, natural latex - in addition to antioxidants - mixed with more stable synthetic latex.
