Medical Propellant
Solstice® Air
A climate-friendly alternative to HFCs and HCFCs, our Solstice® Air offers performance similar to HFC-134a, and is a near drop-in replacement with only minimal changes required to equipment.
Solstice Air is a breakthrough for metered dose inhalers (MDI). A nonflammable alternative to hydrocarbons and low global warming potential (GWP) alternative to hydrofluorocarbons, it is non-ozone-depleting, VOC-exempt (U.S. EPA and CARB), with an ultra-low GWP of less than 1.
