Abstract
A foam cushion with a high water-absorption ability is made mainly from PVC powder and full of open air cells. The air cells in the foam cushion are broken to connect with one another and those on the surface of the foam cushion are broken to connect with open air. Thus, the foam cushion provides a good elastic buffering and high water-absorption ability.
