Abstract

This research investigated the effect of processing parameters on strength properties of Oriented Strand Lumber (OSL) produced from rubberwood (Hevea brasilliensis Muell. Arg.) residues and determined the most optimum parameters for a manufacturing process. The experiment proposed three essential manufacturing parameters, i.e., two resin types (pMDI and PF), three levels of resin content (3, 6, 9%) and three levels of strand length (60, 100, 140 mm). The results demonstrated that the strength properties of the produced OSL were higher than those of solid wood. The most optimum parameters found were pMDI resin, 9 % resin content and strand length of 140 mm.
