E-beam crosslinking is preferred in high-speed manufacturing because it is . In wire and cable production, the jacket can be crosslinked as it passes under the beam at hundreds of meters per minute. Furthermore, because it doesn't require chemical additives like peroxides, the final product is "cleaner," with no chemical residues or outgassing, making it ideal for medical devices and food packaging.
The process begins in an electron accelerator. A tungsten filament is heated to emit electrons, which are then accelerated through a vacuum tube using high voltage (ranging from 150 keV to 10 MeV). These electrons are focused into a concentrated beam and "scanned" back and forth using electromagnets to ensure even coverage across the target material. 2. The Molecular Mechanism How Does The Electron Beam Crosslinking Process...
The electrons collide with the polymer chains, knocking off hydrogen atoms and leaving behind "free radicals" (unpaired electrons) on the carbon backbone. The process begins in an electron accelerator
