    Abstract The poor bonding performance between aqueous adhesives represented by melamine-urea formaldehyde (MUF) resins and reed straw hinders their applications in the field of non-wood-based panels. Multi-hydroxyl polymers are highly reactive and are often used as crosslinkers. This study fabricated a resin with a strengthened cross-linked structure by combining a multi-hydroxyl polymer and MUF resin prepolymer. The reed particleboard was prepared by using this resin as an adhesive and reed stalk as the matrix. The results show that neighboring molecules combined to form C–O–C bonds that strengthened the cross-linked structure of the resin. In addition, the viscosity of the resin was… More >

    Abstract The depletion of log resources encourages research into alternative ways to sustain the wood supply. Therefore, the 4-year-old Rubber Research Institute of Malaysia (RRIM) clones series, RRIM 2020 and RRIM 2025, were chosen as potential raw materials for particleboard in this study. The purpose of this study was to assess the effects of planting density and rubber tree clones on the mechanical and physical properties of single-layer particleboard. The planting densities used were low, moderate-low, moderate-high, and high, representing 500, 1000, 1500, and 2000 trees/ha, respectively. Prior to manufacturing, the RRIM 2000 series clone trees were harvested, cut, chipped, flaked,… More >
