HIGHESTDYNE LEVELREDUCEDBURNTHROUGH

Technology Developed by Xerium’s Stowe Woodward global research and product engineering team, Aurora technology was specially engineered for the most demanding corona treater roll positions in the flexible packaging industry:

• Ideal for treaters operating at the highest dyne levels• Performs well at very high voltage levels• Produces extremely uniform corona • Extremely resistant to roll cover burn-through

Superior Dielectric StrengthSince Dielectric strength determines the maximum strength of an electric field a cover can handle without breaking down, this is a critical factor in preventing premature roll cover damage. New Aurora technology increases dielectric strength by up to 60% over the current conventional cover technology.

Superior Thermal ConductivityThermal conductivity determines how fast a cover can dissipate heat. Higher thermal conductivity helps to stabilize temperature profiles. New Aurora technology improves thermal conductivity by 140%.

Superior Volume ResistivityVolume resistivity is the resistance of a cover to pass an electrical current. High resistivity is required to prevent an electric arc from discharging. Aurora roll covers provide superior volume resistivity to ensure a steady corona discharge.
