E-Beam radiation is a form of ionising energy that is characterised 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 sterilised 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.
Best Suited for:
• Low density, uniformly packaged products
• Polymer modification
• Cross-linking / branching
• Semiconductor enhancement
• Low dose or tight dose ranges
• Biologics and tissue
Key Benefits:
While most materials manufactured for use in the sterile healthcare products are formulated for radiation stability, some materials, certain polypropylenes, for example, experience less breakdown and long-term ageing effects as a result of E-Beam’s shorter exposure time.
Other benefits include:
High Speed, High Capacity Accelerators: Sterilises low-density, uniformly packaged products quickly and effectively.
Dosimetric Dosing:
Eliminates post-sterilisation testing and expedites distribution logistics.
Material Modification:
Electron Beam processing can be used to modify polymers, improve semiconductors switching speeds and change or enhance many other material properties.
