Bomb Calorimetric Analysis and Burning Properties of Medium Density Fiberboard Made from Palm Fiber and Kenaf Fiber Crosslinked with Polyurethane via Pre-Polymerisation Technique

Abstract
The objective of this study to evaluate some fire properties a new hybrid medium density fibreboard (MDF) formulated by utilising a fibre mixture composing of 70:30 empty fruit bunch (EFB) and kenaf (KF) fibre coupled with palm-based pPU functioning as a binder at a ratio of 65:35. Aluminum trihydroxide (ATH) was used as the fire retardant at loading percentage of 0, 5, 10, and 15 wt% of the total mass of the matrix. KF as well as EFB fiber had a size range of 300 to 500 μm. fire resistivity were evaluated by bomb calorimetry and Fire test. The results indicated significant enhancements. The enthalpy computed by bomb calorimetry indicated that the combustion enthalpy of hybrid-MDF rose with increased ATH loading. The fire test exhibited a lower burning rate (from 5.93 mm/s to 3.42 mm/s) when the ATH percentage loading of ATH was raised.
