Researchers at Purdue University have developed a new esterification process for using tannic acid as a fire retardant. Halogenated flame retardants (HFR) have been used as a fire prevention standard for everything from furniture, automotive, and construction to electronic circuit board applications; however, these materials have been found to be highly toxic - even creating birth defects in children and causing cancer. The composition developed by Purdue researchers provides a non-toxic, renewable, and biologically based fire-retardant solution. The tannic-acid based fire retardant exceeded the performance of a commonly used HFR, triphenylphosphate (TTP), in mass loss calorimetry.
