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 .
