Gutta-percha (Palaquium) is a genus of tropical trees native to Southeast Asia and northern Australasia, from Taiwan south to the Malay Peninsula and east to the Solomon Islands. The same term is used to refer to an inelastic natural latex produced from the sap of these trees, particularly from the species Palaquium gutta.
These pipes have strong gutta-percha articulations, so that the oscillations of the balloon may have no effect on them .
