Gutta-percha is a tree of the genus Palaquium in the family Sapotaceae, which is primarily used to create a high-quality latex of the same name. Most commonly sourced from Palaquium gutta, the material is rigid, naturally biologically inert, resilient, electrically nonconductive, and thermoplastic; it is a polymer of isoprene which forms a rubber-like elastomer.
