Abstract
This research aimed to evaluate the physical properties of OSB panels manufactured using Paricá <i>(Schizolobium amazonicum</i>) wood species particles, treated with CCA (chromated copper arsenate) and CCB (chromated copper borate) preservatives, and castor oil based polyurethane resin. Three resin contents were evaluated: 8, 10 and 12%. Results showed that OSB panels manufactured with CCA-treated wood particles did not meet the minimum requirements stipulated by EN 300Code, while OSB containing CCB treated wood particles reached the properties values required for structural applications in dry conditions. Therefore, it was demonstrated the feasibility of using CCB-treated Paricá wood and castor oil based polyurethane resin in OSB production.
