Three layer particleboards were manufactured using hygrothermally treated and untreated tepa (Laureliopsis philippiana) particles with urea-formaldehyde (UF) resin. Hygrothermal treatment consisted of autoclaving particles at 150 °C for 90 min (430 kPa) in a steam saturated atmosphere. A decrease in density and slenderness ratio in treated particles was observed. Modulus of elasticity (MOE) and modulus of rupture (MOR) in static bending, internal bond (IB), and formaldehyde release were determined. An increase in MOE, MOR and IB, as well as a decrease in formaldehyde release, was reported in boards made from heat treated particles.
