Table 4

Combustion parameters obtained from cone calorimeter.

Samples	TTI (s)	PHRR (kW/m^2)	(s)	FIGRA (W/s)	THR MJ/m^2	Residual mass (%)
PA6/MCA	49	928	129	7.2	83	0.4
PA6/MCA-10α-ZrP	55	774	124	6.2	59	26.4
PA6/MCA-30α-ZrP	58	928	116	8.0	60	28.2

TTI: time to ignition; : time to peak heat release rate; FIGRA: fire growth rate; THR: total heat release.
