Product Description Corona Roller for BOPP/BOPET film production lineProduct DescriptionSilicone rubber coated corona roller is a type of roller used in corona treatment processes for films. It is designed to enhance the surface properties of polymeric films, such as polyethylene films, by subjecting them to a corona discharge. The corona discharge helps improve the film's ink retention, coating adhesion, and printability.Advantages of Silicone Rubber CoatingSilicone rubber is a popular choice for Corona Rollers due to its relatively low cost and ease of replacement in the field.It provides a smooth and uniform surface for the film to pass over during the corona treatment process.Silicone rubber coatings have good dielectric properties, allowing for efficient corona discharge and treatment of the film.Considerations for Silicone Rubber Coated RollersWhile silicone rubber coatings are effective, they can be prone to wear and breakdown over time.Ozone generated during the treatment process can react with the rubber material, leading to degradation and breakdown.Rubber coatings may develop pinholes, which can result in spark-through or arcing.Heat generated during the treatment process can also contribute to the deterioration of the rubber coating.Product ParametersShell construction: 2OS Double-shell from Q345BShrinked and welded shafts from Q345Bsurface:Silicone rubber coated, hardness apprx 70HRCDisks and shafts 2-layer painting RALOut of roundness <=0.1mmCylindricity <=0.1mmDynamic balancing G2.5Flow-system: Channels between inner and outer tube separated with welded leading spirals Detailed Photos
