Alumina monohydrate flame retardant

Sample PMMA PMMA- 5% AlOOH PMMA- 10% AlOOH PMMA- 15% AlOOH PMMA- 20% AlOOH [Pg.320]

TTI time to ignition, TOP time of flame out, peak HRR peak heat release rate, THR total heat release, TSR total smoke release, and TCOR total CO release. [Pg.320]

The evaluation of the flammability properties of PMMA and its composites with AlOOH was done using a cone calorimeter (Fire Testing Technology). A 100 x 100 x 4 mm sheet was exposed to a radiant cone (35 kW.m ). The HRR was calculated from the oxygen consumption as measured with an oxygen analyzer. Table 12.1 gathers the parameters obtained in comparison with the pure PMMA sample. [Pg.320]

All results obtained with the cone calorimeter showed a significant improvement of the behavior of PMMA in fire in the presence of AlOOH [Pg.320]

The time to ignition increases by more than 10 s for all PMMA-AIOOH samples. [Pg.320]
