Particleboard production with mixture of six wood species of the Amazonia and Pinus taeda. This study aimed to evaluate the quality of particleboard produced from the mixture of six wood species of the Amazon and Pinus taeda taeda taeda. The Amazonia wood species studied were: Eschweilera odora, Byrsonima crispa, Swartzia recurva, Eschweilera coriacea, Manilkara amazonica and Pouteria guianensis. The experimental design consisted of a mixture of three tropical species, in a proportion of 50[%] and Pinus taeda. Experimental panels were produced with 0.75 g/cm3nominal density, using urea-formaldehyde resin at 8[%] based on solid dry weight of the particles. The panels were pressed with the following conditions: 4.0 MPa specific pressure, 160 °C temperature and a 8 minutes of pressing time. Despite the differences in density, extractives content and pH of the wood, besides of the board compression ratio, clear interactions between these variables and the properties of the particle boards were not found. Based on comparisons with standard requirements and results for the reference species-Pinus taeda, it can be concluded that the wood of six tropical species studied have potential for particleboard production.
