Solstice Propellant is the better choice
Honeywell’s Solstice Propellant HFO-1234ze(E) is better for the environment for aerosol applications that include personal care, cleaners, dusters, warning systems, novelties and freezer sprays, among others. It is a near drop-in replacement for HFC-134a, enabling an easy and cost-effective conversion, while providing a dramatic decrease in CO2 emissions. With a global warming potential (GWP) of less than 1, its widespread global adoption could save more than 14 million metric tons per year of CO2 equivalent emissions, comparable to eliminating carbon dioxide emission from more than 2.5 million cars every year.*
