The effect of cellulose from oil palm trunk (OPT) concentrations (1, 3, 5, and 7 wt %), which were treated various times with urea mixed in NaOH aqueous solution on fabricating cellulose film, were studied. The results showed cellulose from OPT film was successfully prepared through cellulose was dissolved in 7wt% NaOH/12wt% urea aqueous solution at 4°C. The function group was evaluated by FTIR, whereas the physical properties were observed by a camera. The photographs of cellulose film concluded that 5wt% cellulose from OPT had a smoother surface than other ratios. The FTIR result showed that the vibration peak confirmed that cellulose from OPT successfully produced cellulose film. The mechanical properties result showed that urea mixed into cellulose/NaOH suspension after 24 hr presented better mechanical properties than urea mixed immediately. This research provided a friendly environmental system for the preparation of the packaging films.

Formaldehyde emissions from conventional particleboards raise issues of health and safety. One of the potential solutions is binderless particleboards made without using synthetic adhesives. However, the physical and mechanical properties of untreated binderless particleboards are relatively poor compared to conventional particleboards. This research aims to reveal the potential of using steam pretreatment to improve binderless particleboard properties made from oil palm trunk. The oil palm trunk particles were treated with steam pretreatment for different durations of time (20, 40, 60 min). The chemical constituents of the treated and untreated particles were evaluated. The binderless particleboards were made from treated and untreated particles. In addition, panels using untreated oil palm trunk particles with 10% urea–formaldehyde resin were made and used as a comparison. The boards were evaluated according to European Standards. The results indicated that the hemicellulose and starch content gradually reduced with the progression of steam pretreatment. The physical and mechanical properties were improved by increasing steam pretreatment duration. The steam pretreatment was able to improve the properties of binderless particleboards made from oil palm trunk. However, the performance of steam-pretreated binderless particleboard in this study is not compatible with the particleboards made using 10% urea–formaldehyde.

High demand for wooden materials and rises in agricultural areas and forest fires increased the importance of composite particleboard instead of using solid woods. Particleboards are among the most popular materials used in interior and exterior applications. The objective of this study was to examine the physical and mechanical properties of phenol formaldehyde particleboard made from oil palm trunk (OPT) with 11% resin content. Two different board thicknesses were use; 12mm and 16mm. The particle size use in this study was 2mm and 1mm. Phenol formaldehyde (PF) was used as the binder. The result showed that modulus of rupture and modulus of elasticity were perform better at 16mm board thickness with 1.0mm particle size and meet the standard. The internal bonding strength was parallel with bending strength.

Abstract The oil palm trunk (OPT) particle was used as a filler for the manufacture of rigid polyurethane foam composites (RPUFC). The purpose of this research is to investigate the effect of OPT particle content and variation of composite density on the physical and mechanical properties of RPUFC. The RPUFC was created with five different volume fractions of OPT particles (0, 2.5, 5, 7.5, 10 wt%) and three different composite densities (40, 50, 60 kg/m3). The OPT particles, polyols, and isocyanate were mixed, poured and formed in a closed mold. The moisture content (MC), water absorption (WA), compressive strength (CS), screw withdrawal (SW), and internal bonding strength (IB) properties were determined according to JIS A 5908-2003. The flexural strength (FS) properties were determined according to ASTM D790. The physical properties (MC, WA) were increased with increasing OPT particles in the RPUFC. The RPUFC with 2.5% OPT particle was higher in modulus of rupture, modulus of young and CS values compared to RPUFC control. The IB and SW values were increased when 2.5% OPT particles were added to RPUFC. The best PURFCs were produced with the addition of 2.5% particles at a density of 50 and 60 kg/m3.
