Latex is an emulsion of milky appearance and sticky consistency usually white, seldom yellow, orange or red, which is in determined cells (laticifers) of several superior plants and inside mushrooms of Lactarius genus. We speak about "Latex foam" for technical purposes: mattresses, for example, are created with latex foam, which is a primary compound (mix of latex and air). Today latex has a widespread industrial application. The bigger part of latex extracted from plants is transformed into dry rubber. Latex is also growing in the transformer industry. This industry uses it in combination with other materials to manufacture common usage goods (sanitary articles: sterilized gloves, condoms, mattresses, toys, shell, stuffings, pneumatics, carpets, ecc.).
