This work was undertaken with the objective of evaluating the mechanical properties of particleboard manufactured with slash pine residues, resulting from wood mechanical processing. The boards were produced with two types of residues: chips and shaves, used pure or mixed. The adhesive employed was ureia-formaldehyde in proportions of 4, 8 and 12% based on ovendry weight of particles, and densities of 0.6 and 0.7 g/cm3. There were evaluated the bending properties, internal bond and screw withdraw. The bending properties values increased with increasing shaves in the mixture, with board density and proportion of adhesive. It was possible to conclude that boards made of shaves, with larger proportions of adhesive and higher board densities present satisfactory quality.
