Honeywell Solstice® Liquid Blowing Agent (LBA) has a global warming potential (GWP) of 1, and is in the same GWP range as many other foam blowing agents that are considered low GWP solutions, such as hydrocarbons. Solstice LBA provides a path to help solve potential global warming issues facing the industry in Europe, while maintaining high thermal insulation performance and the safety benefits of a nonflammable foam blowing agent. Solstice LBA is REACH registered to 10MT. REACH registration for unlimited amounts is in progress.
Solstice LBA is not listed in the Annex I of F Gas regulation and thus not considered as F Gas.
Solstice Gas Blowing Agent is used as a blowing agent for polyurethanes, polystyrene and other polymers – also as a low GWP substitute for 134a. It has low environmental impact, as measured by its ultra-low GWP of less than 1 and is non-ozone depleting. Solstice GBA is fully compliant with the EU F-Gas regulation.
It has received Notification VIII, Level 1 by the EU Competent Authority for quantities more than 1000 tonnes/annum, allowing commercialization in the EU, as of October 2008.
Solstice GBA is non-flammable by EU A11 test methods. However, the material does exhibit flame limits at elevated temperatures.
The European Union uses a different measure to characterize propensity for ground level ozone formation: photochemical ozone creation potential (POCP). POCP is reported as compared to ethane, which has a POCP of 12.3 (Nielsen, University of Copenhagen).
The POCP of Solstice LBA is estimated to be well below that of ethane and cyclopentane.
Enovate 245fa is non-ozone-depleting and is registered under REACH.
