Metalizing, crosslinking and grafting

Our recommendations


Electronic bombardment and Electron beam (EB)

Potential benefits

  • +Manufacturing of improved polyethylene shrink-wrap films and tubes:
    • Greater impact resistance
    • Glossier and clearer, thanks to greater stretchability
  • +Extremely pure layers
  • +Better hot/cold tack and resistance to aging and stress cracking

Applications

  • Metalizing heat-sensitive substances
  • Crosslinking of plastic sheaths (PVC, polyethylene, polypropylene, PPS and polyacrylate) on electric and telephone cables
  • High-energy electron beam: vacuum melting technique that does not introduce any source of contamination. For example, metallic coating on plastic compounds
  • Low-energy electron beam (below 300 kV): technique that can be used for polymerization (for acrylate materials, for instance), crosslinking and grafting (polymerization on an existing plastic matrix)

An electron beam is generated using two instruments: an electron gun and a magnetic or optical guide to direct the beam. The gun consists of an anode and a cathode operating in a vacuum. When the gun is turned on, the cathode directs a flow of electrons toward the anode, creating a beam that can be focused on the part to be treated.
