Haier, the world’s largest appliance manufacturer, will adopt Honeywell’s new low-global-warming-potential Solstice Liquid Blowing Agent in China to help insulate and increase the energy efficiency of its refrigerators.
Blowing agents such as Solstice LBA allow closed-cell polyurethane foam insulation to expand and provide the majority of the foam’s insulating properties. Solstice LBA can help home appliance manufacturers achieve an 8 percent to 10 percent energy efficiency improvement compared with cyclopentane, which is widely used as a blowing agent in appliance insulation, Honeywell says.
Solstice LBA has an ultra-low global warming potential of 1, which is 99.9 percent lower than HFC-245fa, a commonly-used blowing agent.
The foam insulation used in the Haier refrigerators is formulated and manufactured by Dow Chemical.
Solstice LBA is being adopted by residential and commercial appliance manufacturers worldwide to reduce their environmental footprint and comply with environmental and energy efficiency regulations. It has also been used to help insulate a net-zero energy home project at Purdue University.
Solstice LBA is nonflammable and is not a volatile organic compound. It is approved by the EPA under the Significant New Alternatives Policy (SNAP) Program and is also registered under the European Union’s REACH program. Honeywell’s new world-scale production capacity manufacturing plant for Solstice LBA started up in May 2014.
Blowing agents from Honeywell can be used in a wide range of applications, including spray foam insulation, household refrigerators and freezers, insulated architectural panels and refrigerated shipping containers.
