It increases tensile strength, abrasion resistance, and toughness.
The electrons collide with the polymer chains, knocking off hydrogen atoms and leaving behind "free radicals" (unpaired electrons) on the carbon backbone. How Does The Electron Beam Crosslinking Process...
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 If heated beyond its original melting point, it
Electron beam (E-beam) crosslinking is a physical process that transforms a thermoplastic polymer into a thermoset-like material by using high-energy electrons to create a three-dimensional molecular network . Unlike chemical crosslinking, which relies on heat and chemical catalysts, E-beam processing is fast, precise, and occurs at room temperature. 1. The Physics of the Process Unlike chemical crosslinking, which relies on heat and
These free radicals are unstable and "seek" stability. They migrate along the polymer chains or jump between adjacent chains.
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
