In those flexible vinyl compounds which can accept fillers, alumina trihydrate can significantly improve flame resistance as measured by oxygen index It should be appreciated that degrees of flammability as measured by small‐scale tests such as oxygen index may in no way reflect the relative hazard of these same materials when involved in a fully developed fire. . Over a range of plasticizer concentrations, the lower the concentration of burnable plasticizer, the greater the contribution of hydrate to flame retardancy. Combinations of alumina trihydrate with antimony oxide are especially effective for improving the flame resistance of flexible vinyl compounds.
