Chicle is the name for the gummy sap and the wood of the evergreen sapodilla plum tree (Achras zapota) native to Central and South America. The Aztecs mixed the chicle latex with Asphalt and used it as a Chewing gum called txixtle. Chicle is now primarily sent to the United States for manufacture in chewing gum. The latex gum is tapped from the trees during the rainy season, then pressed into blocks for export. In processing, chewing gum is mixed with Wax, Polyvinyl acetate, sugars, and flavoring. The gum is a thermoplastic material that hardens and becomes less tacky below 32 C.
