Properties of three layers hybrid particleboard from sawdust and acacia mangium / Mohamad Sahzeri Sa'at

The shortage of wood supply as raw material has forced wood-based industries to find alternative raw materials. This study was undertaken to determine the properties of hybrid particleboard from sawdust and Acacia mangium of different density (500, 600,700 kg/m3) and resin content (8:10:8 and 12:10:12). Experimental hybrid particleboard from sawdust and Acacia mangium were bonded with urea formaldehyde (UF) with resin content 8:10:8 and 12:10:12 with the density 500, 600,700 kg/m3. The physical and mechanical properties were accessed. The result shows that the sawdust and Acacia mangium improves some properties of hybrid particleboard, such as bending strength, internal bonding strength and the density except thickness swelling and water absorption. The panels with resin content 12:10:12 showed better MOR, MOE and internal bonding compared to panels with resin content 8:10:8. The density 500, 600 and 700 kg/m3 of panels manufactured using the resin content 12:10:12 was higher compared to panels with resin content 8:10:8. Thickness swelling and water absorption rate decreased when the resin content increased.
