Properties of homogenous and three-layer particleboard from Ketapang and oil palm particles / Siti Aidaliza Subardi, Noorfazurah Mohamad and Sri Normaysarah Abd Rani

In this study, research done to detennine the suitability or strength properties of Ketapang and oil palm particleboard. This research was divided by three part. First part is properties of homogenous particleboard, second part is three-layer particleboard and third part is properties of particleboard from admixture of oil palm and ketapang particles. For the first part, three percentages of Urea Formaldehyde (UF) resin that are 7%, 9% and 11% used for making particleboard. For the second part, for the surface we used 12% of UF while for core, we used 10% of UF with added 1% of wax. While for the third part, we mixed oil palm and Ketapang particles with the ratio (50:50) using 11% of UF. The target density is 650 kgm3. Several types of test are done to determine the strengths properties of its. They are "Modulus of Rupture" (MOR), "Modulus of Elasticity" (MOE), "Water Absorption" (WA) and "Thickness Swelling" (TS). Results obtained shows that Ketapang and oil palm are not suit to the standard to be as new sources in particleboard manufacturing.
