Latest Patents

Hanna's patent revolves around "Carbon Dioxide Blown Polyurethane Packaging Foam." This innovative method pertains to preparing polyurethane packaging foam that is dispensed into a container holding an article for shipping. The invention focuses on reducing the temperature of the foam during dispensing, as well as the maximum reaction exotherm temperature. It involves the reaction of polymeric isocyanate and polyoxyalkylated polyol precursors using water as the blowing agent. Notably, a nucleating agent is integrated within one of the precursors, which plays a pivotal role in lowering the dispensing temperature and also moderating the exothermic reaction as it progresses to completion. Ultimately, this leads to a carbon dioxide blown polyurethane packaging foam exhibiting a density ranging from 0.2 lb./ft³ to 2.0 lb./ft³.
