Abstract: The objective of this study was to evaluate physical and mechanical properties of particleboard produced with different amounts of sorghum crop residues. The panels were made with 0, 15, 30 and 45% of sorghum bagasse and 12% of ureaformaldehyde adhesive. The press cycle used was: 4,0MPa of pressure, 180 °C of temperature for 20 min. To evaluate panels’ quality physical and mechanical tests were carried out. Physical evaluations showed that all properties met the standard CS 236-66, and for every 1% of sorghum added on the panels there was an increase of 1.4 and 1.6% in water absorption at 2 and 24 h of immersion, respectively. For thickness swelling after 2 and 24 h of immersion there was no significant effect with increase in the percentage of sorghum, however it was observed an average value of IE24h only 1.13% higher than required by the standard CS 236-66 which is 30%. Mechanical properties evaluation showed that 13% was maximum sorghum to be added in the panels to meet the standard CS 236-66.
