Resumo: The objective of this study was to evaluate the effect of heat treatment on Pinus oocarpa for, in order to improve the physical properties of plywood panels. 200 x 200 mm sheets were thermally rectified at two temperatures (200°C and 250°C). Nine panels were produced, with three replicates per treatment. Phenol-formaldehyde adhesive was used to glue the panels, with a grammage of 320 g/m². The panels were pressed with a specific pressure of 1.2 MPa for 20 minutes and at a temperature of 160°C. The results indicated that, f or mass loss, there was a significant statistical effect of temperature. For volume loss, a numerical increasing trend was observed with the increase in temperature. For apparent density, water absorption and swelling plus thickness recovery, no significant effect of the heat treatment was detected. Humidity results were significantly influenced by thermal rectification, in which a decrease in this physical property was observed with the increase in temperature. More detailed studies regarding the effect of heat treatment on the properties of plywood panels are recommended.
