Abstract

The amount of water adsorption (WA) determines the dimensional stability of particleboard and flakeboard. Regression models showed that WA is a function of relative humidity, resin type, and board specific gravity, as well as the thickness and slenderness ratio of the wood furnish. Those factors explained 95% of all variation in WA.
