Sterigenics - Electron Beam Irradiation Technology
Electron beam (E-Beam) irradiation is a form of ionizing energy that is characterized by its low penetration and high-dosage rates. The beam – a concentrated, highly charged stream of electrons – is generated by accelerators capable of producing continuous or pulsed beams. As the product/material being sterilized passes the E-Beam, energy from the electrons is absorbed, altering various chemical bonds, damaging the DNA, and destroying the reproductive capabilities of the microorganisms. Sterigenics provides a portfolio of high-energy electron accelerators for industrial applications including the IMPELA(R) accelerator.
Best Suited For
- Low-density, uniformly packaged products
- Polymer modification
- Cross-linking/branching
- Semiconductor enhancement
- Customized dose ranges
- Biologics and tissue
While most materials manufactured for use in sterile health care products are formulated for radiation stability, some materials – certain polypropylenes, for example – experience less breakdown and long-term aging effects as a result of E-Beam’s shorter exposure time. Other benefits include:
- High-Speed, High-Capacity Accelerators
Sterilizes low-density, uniformly packaged products quickly and effectively - Dosimetric Dosing
Eliminates post-sterilization testing and expedites distribution logistics - Material Modification
E-Beam processing can be used to modify polymers, improve semiconductor switching speeds, and change or enhance many other material properties
