When two radicals on neighboring chains meet, they form a permanent covalent bond. This "bridge" is the crosslink. 3. Structural Transformation
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? 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
Because the bonds are covalent (the strongest type of chemical bond), the polymer can no longer melt or flow. If heated beyond its original melting point, it becomes elastic rather than liquid. 4. Key Performance Benefits The process begins in an electron accelerator
It prevents melting and provides "burn-through" resistance, making it essential for high-heat automotive and aerospace wiring.
