This study used Kelempayan wood as a raw material in manufacture of oriented strand board (OSB). This tree is naturally grow in Malaysia. Currently rubberwood supply is getting depleting and limited in resources. The objectives of this study were to determine mechanical and physical properties of OSB and effect of resin content. Target board density was 600 kg/m3 , then phenol formaldehyde (PF) and urea formaldehyde resin (UF) were use as a binder. The quality of the boards were evaluated by determine of bending properties including modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB) strength, thickness swelling(TS) and screw withdrawal. Generally, the mechanical strength increase with an increase in percentage of resin and OSB board from phenol formaldehyde resin is better than those boards from urea formaldehyde resin.
