Two common approachs to flame retard flexible PVC are phosphate ester plasticizers and antimony oxide. When used individually, each displays excellent flame suppressing characteristics. However, the combination of the two has been reported to show lower than expected flame resistance. Zinc borate plays a synergistic role with mixtures of phosphate ester plasticizers and antimony oxide, producing one of the most effective FR composite in this study. A review of this behavior in various PVC formulations is presented.
