Gutta percha contain mainly:
a- Gutta percha 20%.
b- ZINC oxide 75%. ***
c- ZINC phosphate.
Like natural rubber (NR) derived from rubber tree, gutta-percha is a polyisoprenoid. Unlike NR (composed of more than 99% cis-1,4-polyisoprene) which is an amorphous elastic solid, gutta-percha and (gutta-) balata, which contain mainly trans-1,4- polyisoprene, are rigid and partly crystallized at room temperature, which makes them much less elastic.
applications:
The material shows adhesive properties, is a good electrical insulator and is bio-inert. It has been widely used for the coating of submarine or underground cables, until the discovery of polyethylene in 1933. On the other hand, it is not resistant to prolonged UV exposure.
He finds uses in the field of adhesives, in surgery, including dental, and more specifically in endodontics where it is used to seal the pulpal channels once the tooth has been removed.
He was also involved in the composition of golf balls (now made of synthetic material).
Gutta-percha was also widely used in the world of travel, thanks to Maison Moynat, which used, since 1854, this insulating material in the manufacture and doubling of its trunks. Other truncheons then began using the sap to waterproof their products.
It has also been used for the manufacture of everyday objects such as medallions, photo frames, ambrotype or daguerreotype boxes, gramophone records.
It was also used to make bottles to retain the hydrofluoric acid (HF), acid that is used to etch the glass by etching.
History:
Long before the introduction of gutta-percha in the West, the natives of Insulinde (formerly Malay Archipelago) knew how to make knives, handles, walking sticks and various utensils. In 1656, traveling in the Far East, the British John Tradescant was the first European to collect. In the 1840s, William Montgomerie, a physician in the Indian Army, developed practical applications in the field of medical instrumentalization. In 1843, Werner von Siemens designed a machine to coat copper cables, before having the idea of using gutta-percha for the isolation of submarine telegraph cables. In 1845, in Scotland, the first gutta-percha golf ball was cast.
