Effect of Nanometric Metallic Hydroxides on the Flame Retardant Properties of HDPE Composites

Table 5

Data obtained from the cone calorimeter: time to ignition, time to reach the PHRR, heat release rate at the peak (PHRR), total heat released (THR) since ignition to flameout, and time to flameout.

	Time to ignition [s]	Time to peak HRR [s]	Peak HRR [(kJ/s)/m²]	THR [MJ/m²]	Time to flameout [s]
HDPE	63	150	2030.11	110.58	178
M3	86	155	255.35	86.71	593
A3	65	125	257.75	93.64	710
MA3	67	120	265.29	99.91	709
MA3maleic	76	125	240.44	79.61	597
MA3acryl	80	125	256.63	87.53	681

Note: 1 W = 1 J/s.
Data for HDPE was also obtained experimentally, though it is not shown in Figure 3.
