Multilayer Medium Density Particleboard Using Castor Oil-Based Polyurethane Resin and Hevea Brasiliensis Wood

Abstract

This work aimed to study the feasibility of using castor oil-based polyurethane (PU) resin, and rubberwood for the production of particleboards. Multilayer panels were produced using particles taken from RRIM 600 and GT1 clones of Hevea brasiliensis trees. Urea-formaldehyde (UF) and PU were used for bonding the particles. Physico-mechanical characterization was done according to the specifications of the European standards for wood-based panels. The average results were compared to values pre-established by the EN 312/2003 technical standard as well as between the above mentioned treatments. The results indicated that the use of PU and rubberwood has a great potential for particleboards production. The use of PU favors the production of boards with improved physical-mechanical characteristics.
