VCI papers consist of a range of chemically treated papers which provide a proven, highly effective means of protecting ferrous and non ferrous metals from rust and corrosion in storage and shipment.
Method of Protection
The vapour given off by the treated paper will deposit in the form of a molecular film on the metal surface passivating the corrosive action of moisture and oxygen by dissolving in any moisture present and rendering it non corrosive.
Vapour is released at a controlled rate thereby making tight sealing unnecessary moreover, since the rate of release is temperature sensitive, increase in temperature will increase the rate of volatilisation ,thus providing commensurately increased protection a desirable feature since corrosion activity increases with temperature.
Protection is provided in contact with the metal surface as well as in the vapour phase.
Ferro-Pak® VCI papers are specifically designed to protect ferrous metals. MPI papers are designed to protect non ferrous and multi metal composites.
Paper available in rolls, sheets or die cut shapes
Standard roll sizes 760mm -1000mm -1200mm
Paper types kraft, waterproof and scrim reinforced laminates.
Dependent upon conditions of packaging and storage VCI protection can be afforded up to 3 years .
