♦ What is ELECTRON BEAM?

Electron beam processing or electron irradiation is a process which involves using electrons, usually of high energy, to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere. Possible uses for electron irradiation include sterilization and to cross-link polymers.(by wikipedia)

Electron beam processing is used in industry primarily for three product modifications:

  • Crosslinking of polymer-based products to improve mechanical, thermal, chemical and other properties,
  • Material degradation often used in the recycling of materials, and
  • Sterilization of medical and pharmaceutical goods.


♦ APPLICATIONS
