Transcript: latex WHAT IS LATEX Latex rubber is used in many types of clothing. Rubber has traditionally been used in protective clothing, including gas masks and Wellington boots. Rubber is now generally being replaced in these application by plastics. Mackintoshes have traditionally been made from rubberized cloth. Latex is the stable dispersion of polymer microparticles in an aqueous medium. Latexes may be natural or synthetic. Latex as found in nature is a milky fluid found in 10% of all flowering plants . It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums that coagulates on exposure to air. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants. It serves mainly as defense against The cells in which latex is found make up the laticiferous system, which can form 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. Since these vessels are made of many cells, they are known as articulated laticifers. This method of formation is found in the poppy family, in the rubber trees , and in the Cichorieae, a clade in the Family Asteraceae distinguished by the presence of latex in its members. It is also present in another member of the Asteraceae, the guayule plant. latex products and uses : THRE ARE MANY PRODUCTS MADE FROM LATEX HERE ARE A FEW Latex clothing GLOVES CONDOMS The latex of many species can be processed to produce many materials. Natural rubber is the most important product obtained from latex; more than 12,000 plant species yield latex containing rubber, though in the vast majority of those species the rubber is not suitable for commercial use.[ reasons why latex is is used
