WebPlastics exposed to water are subject to several different effects: a) dimensional changes (e.g. swelling) caused by absorption of water; b) extraction of water-soluble components; c) changes in other properties. However, exposure to humidity, immersion and exposure to boiling water can result in distinctly different material responses.
