Pumping times required to reach a vacuum and to stabilize that vacuum are largely determined by the quality of the surface. The "degasing rate" is the determining factor as a key figure as to how much gas is emitted from a surface per unit of time. Over 90% of gases are bonded to the surface in a material layer which is approx. 30µm thick. The degasing is also dependent on the absolute size of the surface.
Added value through POLIGRAT processes
- No gas-conducting surface layer
- Minimized absolute expansion
- Minimized absorption of gases
- Minimizing of pumping times to reach a high ultra-high vacuum by 90%
- Broad stability of the vacuum
