An alternative source of the trans-1,4-polyisoprene is balata, obtained from Mimosups balata, occurring in Venezuela, Barbados and Guyana.

It is similar to Gutta Percha and is used as a substitute. The material contains a high percentage of gums and is more tacky than rubber, but it can be vulcanized.
