Investigation and Development of Air Foam Cushioning
Abstract
Monsanto Research Corporation investigated several water-soluble polymers, especially gelatin, to develop a foam cushioning technique that could be generated on site, and that would be non-toxic and disposable. Gelatin solutions containing 10 to 40% gelatin could be processed into water soluble foam in an Oakes Mixer. This froth foam could be produced by pour-in-place method or could be made into pre-formed and cut ribbon shapes. Sample gelatin foams exhibited high compression set. Work on the foaming of polyvinyl alcohol solution with an Oakes Mixer produced a spongy, water soluble foam in limited quantities. PVA foams cured with resorcinol set up at the same rate as gelatin which is approximately 3 hours after being made. Urea/formaldehyde foams were prepared using a commercial foaming process. These foams were not soluble when immersed in water for 24 hours. UF foams were also prepared which contained percentages of gelatin or PVA. Despite the presence of these water-soluble polymers, the UF foams did not break up when immersed in water.
