The present work describes new gels derived from cheap, abundant and non-toxic
wood bark extracts of phenolic nature, behaving like elastomers. Especially, we show that
these materials might be used as rubber springs. Such amazing properties were obtained by a
quite simple synthesis based on the autocondensation of flavonoid tannins in water at low pH
in the presence of a plasticizer. After gelation and drying, the materials presented elastic
properties that could be tuned from hard and brittle to quite soft and deformable, depending on
the amount of plasticizer in the starting formulation. Not only the materials containing the
relevant amount of plasticizer had stress-strain characteristics in quasi-static and cyclic
compression similar to most commercial rubber springs, but they presented outstanding fire
retardance, surviving 5 min in a flame at 1000°C in air. Neither flame propagation nor drips
were noticed during the fire test, and the materials were auto-extinguishable. These excellent
features make these materials potential substitutes to usual organic elastomers.
