A new HFO polyurethane foam insulation solution for refrigerated cold-drink vending machines helps meet the more stringent Energy Star version 4.0 (USA energy consumption standard) and also delivers weight reduction and improves thermal insulation. The custom-formulated polyurethane insulation solution’s mechanical properties, flow and curing profile reportedly delivered a 10% thermal insulation improvement and a 15% weight reduction (improving resource efficiency) over the incumbent low-global-warming-potential specification.
According to the foam manufacturer, polyurethane rigid foam is one of the best insulation materials available to help achieve energy efficiency targets, reduce costs and mitigate greenhouse gas emissions. Compared to competitive solutions using hydrofluorocarbon foam blowing agents, the HFO solution delivers the same or better performance with a global warming potential 99.9% lower, providing a more sustainable solution.
Note: HFOs (including HCFOs) used as foam blowing agents have low thermal conductivity, an important property for insulation foams.
