The addition of ZnO nanoparticles is an alternative that has been studied in order to improve the properties of Oriented Strand Board panels. However, there is no information about its effect Oriented Strand Board. The aim of this work was to evaluate the influence of the addition of zinc oxide nanoparticles in two different percentages (0,25 % and 0,50 %) on the physical-mechanical properties of Oriented Strand Board panels produced with phenol-formaldehyde resin and on the heat transfer during hot-pressing. Oriented Strand Board panels were produced and tested according to European Standards. The addition of ZnO nanoparticles improved the dimensional stability of the panel, reducing its thickness swelling, and also increased the screw withdraw strength. The heat transfer during hot-pressing increased the temperature more quickly on boards with nanoparticles addition; on the other hand the final temperature of the control treatment was higher. 2023 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48575202003 https://www.redalyc.org/journal/485/48575202003/ https://www.redalyc.org/journal/485/48575202003/html/ https://www.redalyc.org/journal/485/48575202003/48575202003.epub https://www.redalyc.org/journal/485/48575202003/movil 10.4067/s0718-221x2023000100403 en http://www.redalyc.org/revista.oa?id=485 Maderas.
