RUBBER PROCESSING TECHNOLOGY
Production of Natural Rubber •Natural rubber is tapped from rubber trees (Hevea brasiliensis) as latex The trees are grown on plantations in Southeast Asia and other parts of the world •Latex is a colloidal dispersion of solid particles of the polymer polyisoprene in water Polyisoprene (C 5 H 8) n is the chemical substance
