Corona Treatment Closed Cell Crosslinked PE Foam

Corona treatment  sometimes referred to as air plasma. Which is a surface modification technique that uses a low temperature corona discharge plasma. In order to impart changes in the properties of a surface. The corona plasma is generated by the application of high voltage to an electrode that has a sharp tip. The plasma forms at the tip. Do a curtain of corona plasma usually use a linear array of electrodes. Corona treatment closed cell crosslinked pe foam in order to change the surface energy of the material.

All materials have an inherent surface energy. Surface treatment systems are available for virtually any surface format including dimensional objects, sheets and roll goods. Corona treatment is a surface treatment method in the plastic film, extrusion, and converting industries.

Many plastics, such as polyethylene and polypropylene, have chemically inert and nonporous surfaces with low surface tensions causing them to be non-receptive to bonding with printing inks, coatings, and adhesives. Although results are invisible to the naked eye, surface treating modifies surfaces to improve adhesion.
