This work aimed at the evaluation of six (6) Eucalyptus urophylla clones of Companhia Mineira Metais – Unidade Agroflorestal (VM-AGRO) for making particleboard panels. Six (6) panels to each clone studies were produced. About 320g/m² of Phenol phormol aldehyde adhesives Were utilized. The pressing cycle parameters were: pressure of 1.47MPa, temperature of 150ºC and 10 minutes of pressing time. It was concluded that clones of Eucalyptus urophylla show a great potential for production of particleboard panels, since they presented values of physical and mechanical properties above the ones referenced in literature and highly superior to those required by the ABNT Standards 31:000.05-00/2 (static bending) and EN 314-2 (shearing resistance), the tested clones can be used for producing concrete mold (FOR). The clone which stood out the most in all the properties tested was theclone 36.
