The objective of this research was the investigation of dimensional stability of particleboard made with slash pine wood residues. The boards were manufactured with chips and shaves, resulting from sawmill and planermill industries, respectively, used pure or mixed. The adhesive used was urea-formaldehyde in proportions of 4, 8 and 12%, based on the ovendry weight of the particles. Board density investigated were 0.6 and 0.7 g/cm3. The properties evaluated were water absorption and thickness swelling. The best boards were those made of shaves glued with 8 and 12% adhesive content.
