General Information

Item Specification
ASHRAE # R-1234yf
Notes Starting in January 2011, all new vehicle types must have an air conditioning refrigerant with a global warming potential (GWP) below 150. From 2017 on, this will apply to all new vehicles. This is based on the MAC Directive (2006/40/EG), passed in July 2006. Solstice® yf refrigerant can be used in in Europe, Japan, Korea, China and the U.S. Under the ECE Agreement, Solstice® yf refrigerant is also approved in Germany. APPROVALS: Solstice® yf refrigerant is registered under the EU chemical regulation REACH, and is included in the U.S. E.P.A.’s SNAP Program (Significant New Alternatives Policy). With this program, the EPA evaluates new and improved substances that replace ozone-depleting substances.
