Properties of oriented strand board from Kelempayan and Sentang / Suhaini Suria

This study used Kelempayan and Sentang woods as a raw material in the manufacture of Oriented Strand Board (OSB). Currently rubberwood supply is decreasing and limited in resources thus another fast growing species were promoted as very promising raw material for wood composite product. The objectives of this study are to determine the properties and to evaluate the effects of resin content and strand size of OSB properties. Target board density was 700 kg/m³ with applied 9% and 11% of Phenol Formaldehyde as a binder. The quality of the boards were evaluated by determine of bending properties including modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB) strength and thickness swelling (TS) based on BS EN standard. All of the results testing show the mechanical and physical properties of OSB have meet the standard requirement based on BS EN 300:1997 OSB Type 1.
