Measured Data
Specific Heat
Experiments for specific heat [J/(kg K)], or heat capacity, were conducted using a heat flow meter on unconditioned and dried samples at 10 °C, 20 °C, 30 °C and 40 °C.

Thermal Conductivity
Experiments for thermal conductivity [k] were conducted using a heat flow meter on unconditioned samples at 15 °C and 45 °C.

Mass Loss Rate (MLR)
Initial-mass-normalized mass loss rate [1/s] was measured in the simultaneous thermal analyzer experiments at three heating rates: 3 K/min, 10 K/min, and 30 K/min and mass loss rate [g/s] in the cone calorimeter at three heat fluxes: 25 kW/m2, 50 kW/m2, and 75 kW/m2.
Cone Calorimeter Test Notes:
This material did not ignite. One test per heat flux level was conducted for a duration of 30 minutes. The other replicates were conducted for only 10 minutes based on the observation that no significant mass loss occurred after this time in the first replicates.
