Zusammenfassung:The invention relates to a process for plasticizing and shrunk finishing the wood used in furniture manufacturing or for other purposes, with the help of the aqueous solutions of polyethylene glycols with the molecular mass between 62 and 400, at first there being carried out a treatment for emptying the wood pores by vacuuming, followed by impregnating the wood material at pressures between 1,5 and 3 bars, at temperatures between 35 and 80 C and impregnation times between 30 and 120 min. Invenţia se referă la un procedeu de plastifiere şi stabilizare dimensională a lemnului utilizat la fabricarea mobilei sau în alte scopuri, cu ajutorul soluţiilor apoase de polietilen glicoli, cu masa moleculară între 62 şi 400, realizând iniţial un tratament de golire a porilor lemnului prin vidare, urmat de impregnarea materialului lemnos la presiuni între 1,5 şi 3 bari, la temperaturi între 35 şi 80°C şi timpi de impregnare între 30 şi 120 min. ŕ
