Mass Loss Rate (MLR)
Mass loss rate [kg/s] was measured in cone calorimeter experiments at three heat fluxes: 25 kW/m2, 50 kW/m2, and 75 kW/m2.
This material warps and intumesces after ignition. An edge frame and wire grid were used to limit this behavior, yet the sample still expanded vertically through the wire grid, in some cases by more than 2 cm. One additional replicate was conducted per heat flux level without the wire grid to acquire more accurate time to ignition data (HF25_R2, HF50_R4, HF75_R4). Another test was conducted at 25 kW/m2 without either the edge frame or wire grid (HF25_R1) to observe the material burning behavior without intervention.
