ABSTRACT:
This invention relates to a biodegradable foam product and composed of paper fibers or other cellulosic biodegradable material with a superabsorbent polymer and shaped into any desired shape and size and to processes for making same. The foam product is made by blending fibers with up to 25% by weight of a superabsorbent polymer, adding water to the blend allowing it to expand by letting the superabsorbent polymer soak up excess water and drawing off water. Upon drying, the foam product gives off water and the polymer shrinks to its original size leaving voids between the fibers while maintaining the expanded dimensions. The foam product is a soft material especially suited as a cushioning material.
