Latex is the stable, complex dispersion of polymer micro particles (proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums) in a liquid medium that coagulates on exposure to air. Latexes may be natural, synthetic or blend of both. The latex of thousands of species contains rubber, though only latex from several species is suitable for commercial production. Natural rubber is the most important product processed from latex. The vast majority of the world's natural latex is derived from a milky fluid of a rubber tree plant Hevea brasiliensis predominantly found in the rain forest of South America, and is further processed to be used as foam in various products.
