A milky latex obtained from any of several tropical trees of the sapodilla family native to the Malaysian peninsula. Most commercial production of gutta-percha comes from the Palaquium gutta and Palaquium oblongifoia trees. First introduced to London in 1843 by Dr William Montgomerie, gutta-percha is a tough, pliable, moldable rubber-like material though it lacks the elasticity of rubber. On exposure to air and sunlight, gutta-percha oxidizes and becomes brittle. Gutta-percha vulcanizes with sulfur into a hard, waterproof material. From the late 1840s, it was widely used for golf balls, imitation leather, joints in doll limbs, electrical insulation (especially underwater cables), and dental fillings. The name gutta-percha was sometimes used for any dark coloured molding material.
