Electron beam and X-ray industrial processing Polymer crosslinking

Polymer crosslinking
Electron beam crosslinking of the wire insulation is one of the most well-established industrial uses of Electron beam processing. E-beam crosslinking of cable insulation improves the polymer properties. A typical application is automotive wires which require increased resistance to temperature.
Other historical crosslinking applications are heat-shrink tubing and tire crosslinking.
Polymer crosslinking is usually done with accelerators below 3 MeV of beam energy.

E-beam and X-ray penetration properties

10 MeV E-beam has limited penetration in product because electrons have mass as opposed to photon energy radiation of gamma and X-rays.
X-ray’s lower efficiency compared with e-beam is due to the power lost in the X-ray target during the conversion from e-beam to X-ray.
