Gutta Percha in English.
Gutta-percha (Palaquium) is a genus of tropical trees native to Southeast Asia and northern Australasia, from Taiwan south to the Malay Peninsula and east to the Solomon Islands. It is also an inelastic natural latex produced from the sap of these trees, particularly from the species Palaquium gutta. Chemically, gutta-percha is a polyterpene, a polymer of isoprene, or polyisoprene, specifically (trans-1,4-polyisoprene).
The word 'gutta-percha' comes from the plant's name in Malay, getah perca, which translates as "percha sap".
