KEYSUN VCI Masterbatch is a Nitrite-Free anti-corrosion masterbatch designed for both ferrous and most of the non-ferrous metals. The VCI (Volatile Corrosion Inhibitor) additives in Keysun-VCIMB-2100 are partly based on chemicals with enough energy (vapor pressure) to release the active anticorrosion molecules from the film and out in the environmental air to protect the metal packed from corrosion. Extrusion of polyethylene film with SP-VCIMB-2001 will produce a finished product that combines the properties of polyethylene resin and the VCI which will solve the corrosion problems. It is available with color pigment as well as without color pigment. With color pigment masterbatch, the film will give transparent bluish-green color film.
