Self Cooling/Heating Devices

A NASA RTTC assisted International Thermal Packaging (ITP) in the identification of a NASA-developed synthetic polymer that can absorb 1,000 times its weight in water. The desiccant was used in the manufacture of a self-chilling can, a major innovation for packaging food and beverages. The refrigeration device is a small cylinder, fully incorporated into the can. When used in beverage containers, the top of the can is popped, the internal carbonization pressure is relieved, and the self-chilling reaction is induced. Company product line has been expanded to include two related products, and several licensing agreements have been signed.
