Abstract
Medium Density Particleboard (MDP) using sugarcane leaf straw (SLS) particles, a byproduct of the sugarcane harvesting, bonded with synthetic resins (urea-formaldehyde-UF and phenol-formaldehyde-PF) was produced and evaluated. Panels were tested for physical and mechanical properties, according to Brazilian standard ABNT NBR 14810-2 (2018). Variables of two types of resin, two resin contents, two arrangements of board layers and two board densities were analyzed in 12 treatments experimental design. The results grade the panels as Type 2, according to specifications of the Brazilian standard, for internal/dry use. They are also graded as classes M1 and M2 of the ANSI A208.1 (2016) standards for use as industrial MDP. Board density varied from 0.569 to 0.749 g/cm³. Generally, properties improved with the increase of resin content and density. Among the panels bonded with UF the best result was presented with single layer, 12% solids and density of 0.75 g/cm³. Panels glued with 12% PF showed best results of resistance and improved dimensional stability. As an exploratory study, the results are promising and further work is needed to assure the technical use of this agricultural waste, which is usually burned and seen as an environmental burden.
