Since the installation of the firstcustomised corona station for the surface treatment of EPDM profiles over 10 years ago, we have advanced our surface treating technology with our ProfileTEC - a corona treatingsystem for EPDM profiles.

The final effect achieved by the treatment depends on various parameters, including electrode efficiency, duration of the corona discharge, the type of material being treated, the temperature and moisture, contamination, the surface morphologyand similar factors.

Corona treatment eliminates the inefficiencies, safety hazards, and product damage potential of open flame treatment, chemical surface preparation and sanding techniques, while offering improved bonding results.

ProfileTEC consumes less energy in comparison withthe industry average, and this makes itself apparent not only during the initial investment stage, but also in reduced long-term running costs.

A customised ProfileTEC usually consists of 3-5 treating units (heads) and is capable of handling high line speeds (20-25m/min depending on the type of profile) and complex parts made of conductive andnon-conductive rubber.

The advantages of using this technology with EPDM applications are asfollows: * High processing speeds (up to 25m/min, depending on the die), higher on request.
