R-1234yf belongs to a new family of HFOs (hydro-fluoro-olefins) that have a low GWP. R-1234yf is intended for automotive air conditioning systems, some other R-134a applications, and it is a component in some HFC blends to help lower the overall GWP. This product is mildly flammable, but has been deemed safe by itself in new automotive systems.
