gutta-percha (gum resin, <gum resin and gum resin by product>, ... Materials (hierarchy name)) |
|
Note: The inspissated, milky juice of various trees of the Sapodilla family native to the Malaysian peninsula. It is a tough, pliable, moldable rubber-like material, although it lacks the elasticity of rubber and becomes brittle on exposure to air and sunlight. 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-colored molding material. It sets faster than "caoutchouc," which must be heated far longer.

Additional Notes: |
|
| Chinese (traditional) ..... 指稱取自原生於馬來西亞半島的山欖科樹種所得的乳白色濃稠汁液。馬來樹膠為一種強韌且富有可塑性的橡膠狀物質，但卻不具備橡膠特有的彈性，暴露在空氣與陽光下時會變得脆硬。馬來樹膠經過硫化處理後可成為一種堅硬的防水材料。自西元1840年代以來，此材料便廣泛運用於製造高爾夫球、仿皮革、洋娃娃四肢的關節以及電絕緣體（特別是海底電纜）、牙齒填充物等。馬來樹膠一詞有時也用於指稱所有深色的造模材料。其成型速度比需要長時間加熱的「生橡膠」（caoutchouc）來得快。 |
| Dutch ..... Gom die wordt verkregen door het sap te koken van bepaalde bomen die alleen op Borneo, Maleisië en Nieuw-Guinea voorkomen; het is zeer buigzaam en vezelachtig, niet zo elastisch als rubber maar een betere isolator en het is harder na stolling. Wordt bijvoorbeeld gebruikt in de tandheelkunde, in golfballen en elektrische bedrading en gedurende de tweede helft van de 19e eeuw voor speelgoed en poppen. |
| Spanish ..... Goma obtenida al hervir la savia de algunos árboles nativos de Borneo, Malaysia y Nueva Guinea, muy plegable, aunque no tan elástica como el "caucho"; pero mejor aislante, y que se endurece al fraguar. Fragua más rápido que el "caucho", que debe ser calentado más tiempo. Se utiliza en dispositivos dentales, pelotas de golf, instalaciones eléctricas y, en especial durante la segunda mitad del siglo XIX, en juguetes y muñecas. |
