Abstract
The objective of this study was to evaluate some properties of particleboard made using oil palm trunk starch crosslinked with sodium trimetaphosphate as a binder. Three-layer experimental panels were manufactured from homogenous mixture of Acacia mangium and rubberwood. Panels were produced based on two target densities of 0.60 g/cm3 and 0.80 g/cm3. Panels using urea-formaldehyde, native oil palm trunk starch and sodium trimetaphosphate modified starch mixed with 2 % urea formaldehyde as binder also have been evaluated. Panels were evaluated based on physical and mechanical properties. In addition, thermogravimetric, x-ray diffractometry and microscopic analysis were carried out to evaluate the properties of the binder. Some proximate analysis on binder also have been done. Experimental panel with 0.80 g/cm3 density showed better mechanical and physical properties as compared to panel having 0.60 g/cm3. Improvement in mechanical and physical properties also showed by the panel produced using modified oil palm trunk starch with sodium trimetaphosphate as binder, with addition of 2 % urea formaldehyde that panels showed better properties and meet the minimum requirement for internal bond (IB) strength, Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) as stated in Japanese Industrial Standard (JIS A5908) for Type 8 particleboard.
