The latex contains a large amount of resin which destroys most of the elasticity that its rubber might have. Nevertheless it used to be an important source of rubber in Indonesia. A certain variety (var. murtoni King) was cultivated in southern Sumatra for rubber tapping because wild trees there had been tapped to death. It is stated that the bark is very rich in tannin and that the bark cloth is suitable for binding books.
