EB processing is extremely precise and can be controlled to provide the exact level of cure desired. This is done with a computerized system that controls the dose and penetration depth of the electrons. The resulting molecular changes strengthen polymers; cure inks, coatings and adhesives; increase scratch, scuff and abrasion resistance; increase chemical resistance and create memory for shrink film.
High voltage is applied to tungsten filaments inside a vacuum chamber. Filaments are super-heated electrically to generate a cloud of electrons. Electrons are drawn from the cloud and accelerated to extremely high speeds. Accelerated electrons pass through a foil window to penetrate the target product. Electrons cause desired molecular changes in the product.
