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.
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.
