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 ...
Palaquium gutta [2] Scientific classification; Kingdom: Plantae: Clade: Tracheophytes: ... for example Palaquium gutta, are well known for producing gutta-percha ...
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]
Crampton specified a much improved cable. The core of the new cable, again made by the Gutta Percha Company, was to have four conductors, substantially increasing the potential traffic, and insulated with gutta-percha as before. However, the four separate insulated conductors were not laid into a single cable by the Gutta Percha Company.
The balatá is a tree native to Central and South America and the Caribbean. The tree is tapped and the soft, viscous fluid released is a rubber-like material similar to gutta-percha, which was found to make an ideal cover for a golf ball. Balatá, however, is relatively soft.
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.
