Abstract

In recent years, the most important challenge for industries and companies producing wood-based composites was an increase in transportation costs due to increasing demand for a variety of wood materials. On the other hand, the use of lightweight elements in the manufacture of decoration and furniture has received much attention. The objective of this study was to produce and evaluate lightweight fiberboard using ethylene vinyl acetate (EVA). In this study, a mixture of industrial wood chips, two levels of resin (10 and 12%), and three levels of EVA as a foaming agent (1, 3, and 5%) were used to produce light fiberboard. In general, the application of EVA reduces the MOE, IB, and IBS compared with the control (without the use of EVA). However, this reduction can be improved by using 12% glue and 5% EVA. Statistical analysis showed that there was a significant improvement in the physical properties of the boards (reduced WA and TS) due to increased resin and EVA content.
