Gutta-percha latex is biologically [[Chemically inert|inert]], resilient, and is a good [[nonconductor|electrical insulator]] with a high [[dielectric strength]].<ref>{{cite book |last1=Manappallil |first1=John J. |title=Basic Dental Materials |date=30 November 2015 |publisher=JP Medical Ltd |isbn=978-93-5250-048-2 |page=219 |url=https://books.google.co.uk/books?id=7cAqCwAAQBAJ&pg=PA219 |language=en}}</ref> The wood of many species is also valuable.{{citation needed|date=November 2016}}
Western inventors discovered the properties of gutta-percha latex in 1842 through samples sent to England by [[William Montgomerie]],{{citation needed|date=August 2015}} although the people of its [[Malay Peninsula|Malayan]] habitat had used it for many applications for centuries. ([[Michael Faraday|Faraday]] is quoted as having discovered its value as an insulator soon after the introduction of the material to Britain in 1843.<ref>{{cite book|title=The Atlantic Telegraph: Its History, from the Commencement of the Undertaking in 1854, to the Sailing of the "Great Eastern" in 1866.| publisher=Bacon and Company | year=1866| page=108|url=https://books.google.com/books?id=CwszAQAAMAAJ&pg=PA108}}</ref>) Allowing this fluid to evaporate and coagulate in the sun produced a latex which could be made flexible again with hot water, but which did not become brittle, unlike [[rubber]] prior to the discovery of [[vulcanized|vulcanization]].{{citation needed|date=November 2016}}
