Development of Oriented Strand Board (OSB) Using Phenol Formaldehyde Adhesive

Oriented strand board (OSB) was prepared using poplar wood with different resin content of phenol formaldehyde. It was observed that modulus of rupture and screw withdrawal of face and edge was more in oriented strand board as compare to solid wood. Internal bonding strength was very less in oriented strand board as compare to solid wood. It was also observed that most of the properties improve with increase in resin content.
