The objective of the study was to determine the effect  of boron concentration and resin proportion on some properties of rubberwood (Hevea brasiliensis) particleboard. Boron concentrations used were 0, 0.25,  0.50,  0. 75 and  1.0%, and resin proportions in urea formaldehyde were 10, 12 and 14% dry weight basis. The results indicated that the addition of boron compound to porticleboard reduced the values of bending strength, internal bond strength and shear strength but increased the thickness swelling and water absorption of particleboard. Mechanical properties of particleboard  increased with the increase of resin proportion. Thickness swelling and water absorption decreased as the resin proportion  increases.  Physical and mechanical properties  of particleboard  treated with boron compound up to 1% cocentration level and bonded with urea formaldehyde  at 12% or 14% resin propotions were all  met  the  SII  standard requirements,  except  for  internal  bond  strength.  Compared  with  FAO  standard, particleboards that met all the standard requirements  were those with 14% resin proportion.
