Summary

Safe Emulsion Agar gel (SEAgel), is made from agar derived from the seaweed Rhodophyceae which grows freely in the Pacific and Indian oceans and the Japan Sea. Using a comparatively simple production process the gel is formed and freeze-dried. The result is a white rigid foam in any required density from lighter-than-air to strong, machinable forms. It is completely bio-degradable and produces no toxic fumes when burnt. Its thermal conductivity is very low. Uses include packaging, insulation, sound and vibration absorption and, because it is ingestible, as the host material for time released drugs. SEAgel has been released for commercial use from the Lawrence Livermore National Laboratory in California, USA. Its first widespread use will probably be as packaging and sheet insulation. D.W.H.
