Vacuum Behaviour

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

Typical applications

Equipment for research institutes, electronic conduits.
