Gwp c5f8
WebGlobal warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO 2).GWP is 1 for CO 2.For other gases it depends on the gas and the time frame.. Carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e) is calculated from … WebOct 1, 2000 · C4F8 is now mainly used in ultra large scale integrated (ULSI) processes, and C4F6 and C5F8 are expected to be substitutional gases in these processes due to their low global warming potential (GWP).
