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 ...
The Gutta Percha Company was an English company formed in 1845 to make a variety of products from the recently introduced natural rubber gutta-percha. Unlike other natural rubbers , this material was thermoplastic allowing it to be easily moulded .
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 ...
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]
Gutta-percha, recently introduced by William Montgomerie for making medical equipment, was a natural rubber that was found to be ideal for insulating ocean cables. Walker laid two miles (3.2 km) of the cable from the ship Princess Clementine off the coast of Folkestone .

Gutta-percha is radiopaque, allowing verification afterwards that the root canal passages have been completely filled and are without voids. [ citation needed ] Pain control can be difficult to achieve at times because of anesthetic inactivation by the acidity of the abscess around the tooth apex.
