Soft lining materials undergo two processes when immersed in water. Plasticizers and other soluble materials are leached into the water, and water is absorbed by the polymer. The balance between these two processes affects both the compliance and dimensional stability of the materials.
软衬材料浸入水中时会经历两个过程。增塑剂和其他可溶材料会溶出到水中,同时聚合物会吸收水分。这两个过程之间的平衡会影响材料的柔顺性和尺寸稳定性。
