insulating gas alternatives, alternative Gases as gaz sf6 substitute

However, due to its high greenhouse global warming potential with a GWP index of approx. 22,800, SF 6 is the most potent known greenhouse gas, with an atmospheric dwell time of around 3,200 years. For this reason, politics are loudly calling for Alternative Gases. Agreements and regulations such as the Kyoto protocol, the EU F-gas regulation and the Paris climate protection treaty of 2015 have one global goal in common: the reduction of F-gas emissions.
