Silicone Sleeves for Corona Treater

Corona Treater Silicone Sleeve


Corona Treater Silicone Sleeve

Corona Treater Silicone Sleeve was made from refined silicon rubber, it is resistant to high voltage, flame retardant, and produces a uniform corona spark under high voltage. Used for electric spark treatment of plastic films, plastic woven bags, etc., to activate the surface or make micro holes for easy printing and coloring.

Applicable to all kinds of corona treatment sparking machine casing, used as high-voltage electrode, hose and high-voltage output line sheath tube.

It is used as high voltage corona and high voltage electrode roller for corona treatment equipment of BOPP, COPP, POPE and other wide film production lines.
