Gutta-percha (Palaquium gutta) is just rubber/latex, no? The Pará rubber tree (Hevea brasiliensis) overtook it in popularity but it's basically the same natural latex that natural rubber is made from
EDIT: I see they are actually 1,4-polyisoprene but gutta-percha is in a trans configuration while H. brasiliensis latex is in a cis configuration. Not sure if that amounts to any difference in properties https://s10.lite.msu.edu/res/msu/botonl/b_online/e20/20c.htm
It amounts to a huge difference. Cis-polyisoprene has much better stretch and resilience, making it ideal for pneumatic tires. It sealed the economic fates of three continents at once.
