Description and Chemistry of Gutta-percha
- Gutta-percha trees are 5-30 meters tall and up to 1 meter in trunk diameter.
- The leaves are evergreen, glossy green above, and often yellow or glaucous below.
- The flowers have a white corolla with acute lobes and are produced in small clusters along the stems.
- The fruit is an ovoid berry, 3-7 cm long, containing one to four seeds.
- Gutta-percha is a polyterpene, a polymer of isoprene.
- It exists in alpha and beta forms, with the alpha form being brittle at room temperature.
- The trans structure of gutta-percha crystallizes, leading to a more rigid material.
- Latex rubbers are amorphous, while gutta-percha is crystalline.
- Gutta-percha is a thermoplastic material.

Applications, Properties, and Manufacturing of Gutta-percha
- Gutta-percha was widely used in the telegraph industry as an insulating material for underwater cables.
- It was also used in dentistry for root canal treatments and silk painting as a resist technique.
- Gutta-percha is a natural latex produced from the sap of various trees, primarily Palaquium species.
- It is highly flexible, durable, and resistant to water and chemicals.
- The material has excellent electrical insulation properties and can be softened and molded when heated.
- The extraction of gutta-percha involves tapping the tree trunks and collecting the latex, which is then processed and molded into desired forms using heat and pressure.
- Manufacturing processes have evolved over time, with injection molding being used for dental applications.
