When two radicals on neighboring chains meet, they form a permanent covalent bond. This "bridge" is the crosslink. 3. Structural Transformation

These free radicals are unstable and "seek" stability. They migrate along the polymer chains or jump between adjacent chains. How Does The Electron Beam Crosslinking Process...

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 When two radicals on neighboring chains meet, they

The electrons collide with the polymer chains, knocking off hydrogen atoms and leaving behind "free radicals" (unpaired electrons) on the carbon backbone. A tungsten filament is heated to emit electrons,

Crosslinked materials can be stretched while hot and "frozen" in place; when reheated, the crosslinks pull the material back to its original shape (the principle behind heat-shrink tubing). 5. Why E-Beam Over Chemical Methods?
