EDGE - Foams and Fibrebased Material
Polymer foams, mostly for adhesive tapes, play an increasingly important role in profitable converting applications. Nevertheless, economy and ecology do not always allow for fluorinated foams. On the other hand, new light weight foams are no good candidates for corona treatment, particularly not in case of higher thicknesses.
In this case Plasmawerks EDGE technology offers the ideal tool for polymer foam treatment. With EDGE there is absolutely no risk of perforating or burning the foam, since the systems can be operated in a standard corona mode, also polymer films will be treated without compromise.
