PROPATECH VCI PAPER
Anti-corrosive paper coupled with polynet
Reinforced protection for heavy loads: anti-corrosive paper with net and film for sharp-edged and irregular manufactured goods.
The anti-corrosive paper PROPATECH VCI PAPER coupled with polynet represents the most robust solution for the protection of heavy metal manufactured goods with irregular shapes. This innovative composite material combines three fundamental elements: packaging paper impregnated with VCI molecules for anti-corrosive protection, reinforcement net for mechanical resistance and polyethylene film for waterproofing. This triple combination creates a complete protective system that unites anti-corrosive efficacy, structural robustness and barrier against atmospheric agents. Besides polyethylene, PROPATECH VCI paper can also be coupled with other materials such as aluminum, fabric or plastic nets. This way it is possible to create ad hoc materials for specific usage and protection needs, with different and complementary characteristics.
The main advantage of this product is the ability to handle difficult loads where traditional paper would be inadequate. The reinforcement net completely prevents tears caused by sharp edges, rough surfaces or mechanical stress during handling, while maintaining intact the VCI protective action. It is the ideal solution for directly wrapping large-sized pieces, lining containers of different materials (cardboard, wood, metal, plastic) and for all those applications where maximum resistance combined with total anti-corrosive protection is needed. The result is a safe packaging that offers product integrity and zero risks of damage during transport and storage.
Problems solved by this product
There are 2 types of VCI paper: double-faced paper, impregnated on both sides, or one-sided PE coated paper. This latter is active only on one side, while the other consists of a barrier film able to keep the VCI within the package.
VCI film is always active on one-side.
On both VCI paper and film the active side (to be oriented toward the metal) is easily distinguishable, as it is opposite to the printed side.
The quantity of VCI to be used in order to effectively protect goods against corrosion depends on many factors, being the most relevant: shipping time, external conditions (e.g. by sea, by land), and type of product. We strongly recommend to contact us in order to determine the most efficient solution and design the most appropriate package.
VCI (Volatile Corrosion Inhibitor) can be used for all products that need a corrosion protection inside the packaging such as steel coils, automotive spare parts, engines, complete machineries and all kind of metal parts.
Ferrous metals contain iron, for example steel, whilst non-ferrous metals do not contain iron, for example zinc, magnesium, and copper.
VCI anticorrosive products can be stored for up to a year and a half, but they must be kept sealed in the original package and not opened.
VCI is a volatile substance so, once the packaging is opened, it volatilize from metal in one or two hours and it will not leave resuduals.
VCI is a complex combination of substances which sublimate and form a thin invisible layer able to neutralise corrosive agents, such as water vapour, oxygen, salty air, sulfur-based gases, and polluting agents commonly present in the air.
Products for VCI (Volatile Corrosion Inhibitor) protection are used, during shipments and storage, to preserve and protect metals against corrosion. Propagroup has figured out and developed products for VCI protection, helping companies to preserve goods quality for a long time. The anticorrosive VCI products guarantee quality perseverance of shipped and stored materials, no claims for oxidation, considerable saving and big customer satisfaction. Propagroup created Propatech VCI system that, thanks to the reduction or even elimination of use of oil and greases, guarantees that the product remains intact, clean and ready-to-use. Propatech VCI doesn't leave traces and it is not dangerous, this is very important for protection, preservation, safety and saving. Propagroup is leader to solve problems of corrosion, humidity and impacts of goods during transport. Propatech VCI product range for metal protection includes the following products:
Papers, double face and polythene anticorrosion products, in addition to rolls, sheets and bags;
Films, anticorrosion plastic materials like Propatech VCI film, Propaskin, Propasteel, Propastretch and Propabol;
Emitters and diffusers of VCI substances like Propatech VCI Noxy, foams, tablets and anticorrosive pill bags.
VCI stands for Volatile Corrosion Inhibitor.
There are different types of VCI depending on metal to protect.
The chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.
Diffusion is the volatile distribution of VCI molecules into the packaging.
PROPATECH VCI products for the protection against corrosion are free from nitrites.
Nitrites are made of a nitrogen atom and two oxygen atoms negatively charged and it can be found in some anticorrosive VCI products on the market. Its presence has to be allowed and declared from the producer.
A corrosion reaction in which the corroded metal forms an oxide; usually applied to reaction with a gas containing elemental oxygen, such as air.
Transformation from a solid to a gaseous state of VCI molecules starting from the protective material (paper, film, diffusers, foams, etc...).
VCI is a Volatil Corrosion Inhibitor that can sublimate, from a solid to a gas state, and form a thin invisible layer able to neutralize corrosive agents such as: water vapour, oxygen, saline atmosphere, sulphurous gases and the most common industrial environmental pollutants present in the air.
The Volatile Corrosion Inhibitor is a chemical substance that inhibits electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
