EB (Electron Beam)
EB (electron beam) can bring out the full potential of materials used in our daily lives.
EB, which is a type of energy line, artificially accelerates electrons to use as beams.
EB has a high energy and can irradiate while closely controlled. Therefore, it can quickly perform surface treatment of materials and sterilization in a large quantity.
EB has been used for a wide range of things in our daily lives such as wall papers, flooring, packaging materials, and prints.
Application Examples and Features
EB irradiation can modify materials in various ways.
Especially, EB is used for the following effects: cross-link (improved functionality), polymerization (curing), graft polymerization (added functionality), and sterilization.
These effects help develop and manufacture various high-functioning materials.
4 Effects of EB (Cross-link, Polymerization, Graft Polymerization, and Sterilization)
Cross-link
Function enhancement
EB generates cross-link effects between high polymers and modifies polymers into mesh-like structures. It enhances strength and heat resistance.
Polymerization
Curing
Curing bonds small molecules to make high polymers. It is used for curing coating materials, print ink, and adhesives. The below is the list of its advantages:
- It can create hard coating films
- It doesn't get affected by the color of the coating film
- No initiator required
- It can create weatherproof coating films
- Solvent-less process reduces the environmental load
Graft Polymerization
Added functions
Graft generally means a twig inserted into a slit of the trunk or stem of a plant. In this case, graft means chemically bonding molecules of other functions into high polymer materials such as films and fibers. Graft polymerization adds a new function to the main material such as ion adsorption, antibacterial treatment, and deodorization.
Sterilization
Electron Beam Sterilization
EB can sterilize without using chemicals. Since there is no concern for chemical residues and you can sterilize at room temperature, EB is suited for plastics that are sensitive to heat. You can achieve a disinfecting grade that is required in packaging materials for food and medical devices.
