Polyethylene glycol (PEG) treatment effectively stabilizes the dimensions of wood and protects it from degradation by replacing moisture and occupying cell spaces.

The analysis

The retrieved literature (such as papers 1, 2, and 9) specifically demonstrates that polyethylene glycol (PEG) impregnation alters wood-water relations, provides high anti-shrinkage efficiency, and serves as an effective conservation method for stabilizing the dimensions of wood (such as waterlogged archaeological wood). There are no refuting papers.
