This research was developed to evaluate the potential use of the woods Schizolobium amazonicum (Paricá) and Cecropia hololeuca (Embaúba) for manufacturing particleboard. Were made panels with the densities of 0.70 g/cm³, using mixtures of urea-formaldehyde resin and wood particles of Paricá and Embaúba, in proportions of 75, 50 and 25%. The Pinus taeda wood was used as the reference. The panels were pressed at the temperature of 160ºC, pressure of 40 kgf/cm², for 8 minutes. The evaluations of the properties of water absorption, thickness swelling, internal bond, modulus of elasticity and modulus of ruptures, showed that the woods of Schizolobium amazonicum (Paricá) e Cecropia hololeuca (Embaúba) are technically feasible for particleboard manufacture.
