SES has introduced a 2.0 closed-cell spray polyurethane foam (ccSPF) formulated with Honeywell’s Solstice Liquid Blowing Agent (LBA) for use in wall insulation applications. SES joins a list of companies that have switched from hydrofluorocarbon (HFC) foam blowing agents such as HFC-365mfc and HFC-245fa to Solstice LBA in ccSPF systems, well ahead of environmental regulations calling for a phaseout of HFCs due to their high GWPs. More than 190 countries recently agreed to an amendment to the Montreal Protocol that would phase down the use of HFCs beginning in 2019.
Solstice LBA, which is based on next-generation hydrofluoro-olefin (HFO) technology, complies with changing regulatory requirements aimed at reducing climate impact, while also providing improved foam performance compared to HFCs. Blowing agents are an important ingredient in closed-cell foam, allowing it to expand and enabling its insulating performance.
“SES is proud of its commitment to sustainable solutions and innovation,” said Charles Valentine, chief operating officer, SES Foam. “Having built our open-cell foam business around sucrose-based technology, we believe that adopting Honeywell’s Solstice LBA in our closed-cell foam aligns with our customers and environmental focus. Our expertise is unique in that many of our staff are former spray foam contractors, so they have insight into customers’ needs, and can provide the support and products they require to succeed.”
“Honeywell is committed to helping industry leaders like SES create solutions such as using Solstice LBA in its closed-cell foam,” said Laura Reinhard, global business manager for spray foam, Honeywell. “Not only does Solstice LBA provide SES with an environmental solution, it has helped their 2.0 product formulation deliver foam performance.”
Solstice LBA has a low global-warming-potential of 1, which is 99.9 percent lower than HFCs and equal to carbon dioxide. It is nonflammable (ASTM E-681) and is not a volatile organic compound per the EPA. Solstice LBA is listed under the EPA’s Significant New Alternatives Policy (SNAP) program. In Europe, it is not listed in the Annex I of F-Gas regulation and thus not considered an F-Gas. It is also registered under the European Union’s REACH program.
Solstice LBA is used in a variety of rigid foam insulation applications, including spray foam insulation, residential and commercial refrigeration equipment, and insulated metal panels, as well as flexible foam applications, such as molded and slabstock foam, and integral skin.
