Utilization of waste tire rubber in the manufacture of particleboard was investigated, using the same method as that used in the wood-based panel industry. The manufacturing parameters were: a specific gravity of 0.65 and waste tire rubber content (10/90, 20/80, and 30/70 by wt% of waste tire rubber/wood particle). Two resin types, melamine/urea formaldehyde (MUF) and polyisocyanate, were used in the experiments. Average modulus of rupture values of MUF bonded particleboards with rubber crumbs were between 13-58% lower than the average of the control samples while polyisocyanate bonded particleboards were 12-51%. Water resistance of the boards improved with the increase in rubber crumb/wood particle ratio. Thickness swelling values of the MUF bonded particleboards decreased from 14-53% while polyisocyanate bonded particleboards were 9-48% as compared to control samples.
