 The extraction of latex from a tree; latex is used in Rubber production Latex, as found in nature, is the milky sap of many plants that coagulates on exposure to air. It is a complex emulsion in which proteins, alkaloids, starches, sugars, oils, tannins, resins and gums are found. In most plants, latex is white, but some have yellow, orange, or scarlet latex.

Sources The cells or vessels in which latex is found make up the laticiferous system, which forms in two very different ways. In many plants, the laticiferous system is formed from rows of cells laid down in the meristem of the stem or root. The cell walls between these cells are dissolved so that continuous tubes, called latex vessels, are formed. This method of formation is found in the poppy family, in the rubber tree, and in the Cichorieae, a section of the Family Asteraceae distinguished by the presence of latex in its members. Dandelion, lettuce, hawkweed and salsify are members of the Cichorieae.

In the milkweed and spurge families, on the other hand, the laticiferous system is formed quite differently. Early in the development of the seedling latex cells differentiate, and as the plant grows these latex cells grow into a branching system extending throughout the plant. In the mature plant, the entire laticiferous system is descended from a single cell or group of cells present in the embryo. Species See text. ...

Function and usage Many plant functions have been attributed to latex. Some regard it as a form of stored food, while others consider it an excretory product in which waste products of the plant are deposited. Still others believe it functions to protect the plant in case of injuries; drying to form a protective layer that prevents the entry of fungi and bacteria. Similarly, it may provide some protection against browsing animals, since in some plants latex is very bitter or even poisonous. It may be that latex fulfills all of these functions to varying degrees in the numerous plant species in which it occurs. Image File history File linksMetadata No higher resolution available. ...

Latex has many uses, from clothing to paint, but its first and foremost is rubber. Chicle, widely used as a base for chewing gum, is another latex product. Latex paint uses synthetic latex as a binder, which is not flammable, has little odor, and cures to form a dry paint film. Natural latex, which is nearly chemical free, is used in the manufacturing of natural Latex Mattresses, beauty application pads, and cushioning. It is a notably supperior product to polyurethane alternatives proven by its fifteen plus year life span and comfort. Its considered the cadillac of cushioning foams.

As latex has a protein found also in bananas, care should be taken to ensure people are not allergic to both.

Latex clothing -
Latex is used in many types of clothing. It is different from rubber in that it is less refined and often thinner. Worn on the body (or applied directly by painting) it tends to be skin-tight, producing a "second skin" effect. It has a shinier finish than rubber. Latex rubber is used in many types of clothing. ...
