Abstract
A durable, conformable, absorbent, hydrophilic, polymeric latex foam composition having a free absorbent capacity of at least 5 grams of a 0.9 weight percent aqueous saline solution per gram of foam and capable of vertically wicking said aqueous saline solution to a height of greater than about 5 cm. In a preferred embodiment, after compression, the latex foam composition remains thin until wet, whereupon it expands and exhibits a high free absorbent capacity and high vertical wicking height.
