Palaquium gutta. 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. The material is rigid, naturally biologically inert, resilient, electrically nonconductive, and thermoplastic, most commonly sourced from Palaquium gutta; it is a polymer of isoprene which forms a rubber-like elastomer.
Reels of gutta-percha insulated cable being loaded at the Greenwich works shortly after the merger into the Telegraph Construction and Maintenance Company. Gutta-percha insulated core rapidly became the chief product of the company. [21] In 1851–1852 they produced 1,300 nautical miles (2,400 km) of it.
It too has been synthesised and extracted from plant sap, the latter resin being known as gutta-percha. These were widely used as an electrical insulator and as components of golf balls. Annual worldwide production of synthetic polyisoprene was 13 million tons in 2007 [1] and 16 million tons in 2020. [2]
Some natural rubber sources, such as gutta-percha, are composed of trans-1,4-polyisoprene, a structural isomer that has similar properties. Natural rubber is an elastomer and a thermoplastic. Once the rubber is vulcanized, it is a thermoset. Most rubber in everyday use is vulcanized to a point where it shares properties of both; i.e., if it is ...
The India Rubber, Gutta Percha and Telegraph Works Company was a London-based company based in Silvertown, East London.It was founded by Stephen William Silver in March 1864 as Silver's Indiarubber Works and Telegraph Cable Company Ltd. [1] However in July that year the name was changed to the India Rubber, Gutta Percha and Telegraph Works Company.
J. Pascal had long been a hardware chain only, but subsequently expanded to furniture retailing. Until the 1970s, the company's name was J. Pascal Hardware Co. After the furniture division was created in the 1980s, the company's corporate name became J. Pascal Inc.
Charles Stent (1807–1885) was a 19th-century English dentist notable for his advances in the field of denture making.. In 1847, English dentist Edwin Truman (1819–1905) introduced gutta-percha as a material for making dental impressions; however, this was unsatisfactory for several reasons, including its tendency to distort upon removal from the patient's mouth, and to shrink upon cooling.
The seeds of Palaquium gutta are used to make soap and candles, occasionally in cooking. The latex is used to make gutta-percha . The timber is logged and traded as nyatoh .
