Table 2 Detail data of cone calorimeter measurements of RPU and LRPU foams

From: Lignosulfonate/APP IFR and its flame retardancy in lignosulfonate-based rigid polyurethane foams

Sample	Lignin contents (%)	EHC^a (MJ/kg)	CO^a (kg/kg)	T_PCO^a (s)	AMLR^a (g/s)
RPU	0	19.3	0.042	25	0.021
L₅RPU	5	17.9	0.042	120	0.018
L₁₀RPU	10	18.1	0.044	103	0.016
L₁₅RPU	15	14.7	0.051	121	0.015
L₂₀RPU	20	13.3	0.047	63	0.015
L₂₅RPU	25	18.2	0.043	39	0.013
L₃₀RPU	30	18.7	0.039	44	0.014

RPU and LRPU refer to rigid polyurethane and lignosulfonate-based rigid polyurethane, respectively
^aEHC, CO, T_PCO, and AMLR refer to the effective heat combustion, the carbon monoxide production, the time-to-peak CO production, and the average mass loss rate, respectively
