Hydrogen embrittlement of polymers
WebHydrogen Storage vessels are especially susceptible to embrittlement. How can you minimize this? By controlling the hydrogen factors, stress factors, and vessel material factors. Hydrogen factors include things such as the pressure, temperature, and purity of … WebThe aging behavior – particularly the embrittlement – of the encapsulation polymer under UV-exposition was investigated using ethylene vinyl acetate (EVA) as an example. A detailed numeric model of a PV-module and its layer setup regarding front glass, encapsulation, silicon-cells and copper interconnectors was created.
