For sealing materials in contact with gases such as hydrogen, a consideration of gas permeability is of elementary importance for the assessment of safety, functionality and reliability. The aim of the presented study is to give an overview of the permeation behavior of thermoplastic vulcanizates (TPV) and ethylene-propylenediene rubber (EPDM) towards hydrogen under consideration of processing influences. A comparison of TPV and EPDM shows a differentiated permeation behavior.

According to an article by M. Rigby, S. Park, et al., published in the international journal of science Nature 569, p. 546 – 550 (2019), the recovery of the stratospheric ozone layer relies on the continued decline in the atmospheric concentrations of ozone-depleting gases such as chlorofluorocarbons. The atmospheric concentration of trichlorofluoromethane (CFC-11), the second-most abundant chlorofluorocarbon, has declined substantially since the mid-1990s.
