Effect of High Temperature Additives in Fire Resistant Materials

The effect of high temperature additives in intumescent systems was examined in a laboratory environment. A matrix of ceramic fibers/minerals was incorporated into two intumescent systems. The material performance was determined using a series of small-scale propane-fired furnace tests based on the ASTM E119 time-temperature curve for fire tests of building construction and materials. Several formulations were identified using a 15-minute screening fire test before testing for a longer time period.
