The object of this study was to investigate the dimensional stability (DS) for particleboards (PBs) made by changing factors of board preparation, this is, density of boards, resin content, adhesives, particle size and wood species. The measurement of moisture absorption, in-plane linear expansion (LE) and thickness swelling (TS) were done to evaluate DS of PBs.
The results are summarized as follows: It was clear that the values of LE and TS were decreased with decreasing density of boards and increasing resin content. DS of adhesives used was superior in order of phenolic resin (PF)>Isocyanate resin (IC)>Urea resin (UF). The oriented boards prepared from birch and Hinoki showed excellent resistance against moisture absorption, and anti-swelling efficiency on their LE values (L-ASE) in 50% and 35%, respectively.
