 //"The name ‘gutta’ means ‘getah’ in Malay language means latex/ gum; while ‘percha’ is the local name of the tree. The gutta percha or nyatoh taban merah (Palaquium gutta) from the Sapotaceae family is a medium-size timber tree which can reach the height of 35 m. This species is found in lowland forests in Peninsular Malaysia, Singapore, Sumatra and Borneo. Gutta percha is a lightweight hardwood suitable for the making of interior decorative items and panel. Its leaves are yellowish-green or rusty green with copper-coloured veins and the flowers are small. The tree begins producing white rubber after 15 years’ old. At room temperature, gutta percha latex is hard but when heated, it can be moulded into various shapes. Gutta percha was first introduced in Europe and marketed after it was known to have the appropriate properties (flexible, able to withstand high pressure and cold temperature) for coating submarine electric cables. In addition, the latex is also used as a golf ball coating, in dental treatment as well as for the making of pistol grip and jewelry."// \\ //"The name ‘gutta’ means ‘getah’ in Malay language means latex/ gum; while ‘percha’ is the local name of the tree.
