A review on methods for controlling the dimensional stability of particleboards. a second pressing at the same temperature as the first Pressing may possibly have three main effects on PF resin bonded particleboard durability: (a) the effect of mechano-sorptive behaviour; (b) the effect of softening of cell wall polymers; (c) the improvement of cure of PF resins. Effects (a) and (b) may accelerate the removal of the recoverable part of residual compressive strain replace of it with the development of the viscous component, thus, relax the compressive stresses.
