Based on the CSA/ANSI standard, static exposures in hydrogen experiments were performed up to 100 MPa at 120 °C. Characterization before and after exposure was conducted by means of density and hardness measurements, dynamic mechanical analysis (DMA), tensile tests, compression set, FT-IR and AFM analyses to assess effects after decompression. While the effect of high-pressure exposure is significant immediately after exposure, most of the physical and mechanical properties recover after 48 hours. FT-IR, AFM, SEM and compression set results indicate, however, permanent effects.

T1 - Morphological investigations on silica and carbon-black filled acrylonitrile butadiene rubber for sealings used in high-pressure H2 applications N2 - Effects of NBR formulations on properties for high-pressure gas systems were tested. Functionalized silica enhances typical properties to a comparable range like CB. The balance of additives results in suitable RGD performance. Silica filled NBR shows lower H2 uptake compared to non-plasticized CB filled NBR. Morphology of CB filled NBR is less affected by H2 than silica filled grades.
