Ask Google Shopping for Gutta Percha and all you get is dental supplies. It comes from trees and sounds a bit like rubber, but it is different. Some notes I collected from Wikipedia articles about Latex, Gutta-Percha and Natural Rubber:

Gutta-percha was difficult to harvest. Only trees that had grown for 35 years or more were economical to harvest. Felling a single tree could yield 12 catties (16 pounds) of gutta-percha; cutting boreholes to harvest gutta-percha from a living tree yielded much less, and often killed the tree anyway due to fungal infection.

Rubber latex is extracted from rubber trees. The economic life of rubber trees in plantations is around 32 years, with up to 7 years being an immature phase and about 25 years of productive phase.

Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms, latex clothing, and balloons.

The latex of many species can be processed to produce many materials.

• Balatá and gutta percha latex contain an inelastic polymer related to rubber.
• Chicle and jelutong tree latex was used in chewing gum.

Gutta-percha . . . is a polymer of isoprene which forms a rubber-like elastomer.

Rubber, also called India rubber, latex, Amazonian rubber, caucho, or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds.
