Utilization of High-density Raw Materials for PanelProduction and its Performance

The residues generated in the furniture industry have not yet been optimally used for panel production. One reason for this is that residues from the furniture industry contain high-density hardwood, which is not considered suitable as a raw material in panel production. In this study, the possibility of high-density hardwood species for panel production was investigated. Matoa, one of high-density hardwood species, was utilized for panel products targeted for interior application in flooring heating systems. Methylenediphenyldiisocyanate (MDI) resin was applied as adhesive in a rotating blending box at 6% based on oven dry weight. The mat panel was hot pressed for 5 minutes at a press temperature of 180 °C and an initial pressure of 3 MPa. This study showed that matoa can be used for panel products with limited purposes in non structural and interior uses. It has sufficient physical properties of thickness swell and moisture content, but low quality of water absorption. In term of mechanical properties, the boards manufactured had adequate bending properties and internal bonding which met the requirement of JIS type-8, except for particleboard made from planer shavings. It is known that particle shape and size significantly affect the panel properties of matoa.Hammer-milled matoa from mill residue can be an alternative for panel production in the future.
