Abstract
Provided is a low water paper product comprised of wood pulp having at least some of the water present in the amorphous regions of the cellulosic pulp fiber structure replaced with a polyhydroxy polymer. The preferred polyhydroxy polymer used to replace the water is polyvinyl alcohol. The resulting paper product exhibits improved dimensional stability, particularly when exposed to water or water vapor. Characteristics of the paper product make it quite suitable for use in transformers.
