    However advantageous the above properties are, Sulfur Hexafluoride is considered to be a fully fluorinated compound (FFC). Since FFC’s have atmospheric lifetimes of up to 50,000 years, these potent greenhouse gases could contribute significantly and, essentially, permanently to global warming if emissions continue to grow.
