dc.description.abstractThis study was designed to evaluate the influence of adding poly-3-hydroxybutyrate [P(3HB)] on the properties of particleboards made from oil palm (Elaeis guinensis) trunk. Two types of boards which are particleboards made up of steam treated particles and untreated particleboards, were manufactured from oil palm trunk particles with a target board density of 0.8 g/cm3, pressing temperature of 180 °C, pressing pressure of 5 MPa and pressing time of 20 min. The steam treatment was carried out by subjecting the oil palm trunk particles at a temperature of 130 °C for 30 min before those particles was used for particleboard production. Poly-3-hydroxybutyrate in the form of freeze dried and pure were used as additives at various loadings namely 1%, 3%, 5% and 10% based on the oven dry weight of oil palm trunk particles used. The influence of P(3HB) towards untreated and steam treated particleboards were analyzed both physically and mechanically based on Japanese Industrial Standard, JIS. Further analysis such as surface roughness, gas chromatography, thermogravimetric analyses, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy and differential scanning calorimetry were also carried out. Mechanical properties and dimensional stability of panels were improved with increasing amount of P(3HB) added for both type of panels. All the panels meet the minimum requirement of JIS for mechanical properties only. The untreated particleboard with addition of 10% of pure P(3HB) seems to exhibit highest value for the mechanical and physical properties. Based on the findings, P(3HB) could be considered as a potential additive to improve the overall properties of such binderless particleboard.en_US
