PROPABOL VCI
Anti-corrosive bubble wrap polyethylene
Comprehensive triple-action protection: anti-corrosive, shock-resistant and scratch-resistant in a single transparent material.
PROPABOL VCI represents a revolutionary innovation in the industrial protection sector, created through the intelligent coupling of bubble wrap polyethylene with PROPATECH VCI FILM added with volatile corrosion inhibitor. This unique solution combines three fundamental protective functions in a single material: anti-corrosive protection thanks to VCI molecules, impact protection through the cushioning effect of air bubbles, and protection from friction between parts during handling. All while maintaining complete transparency that allows correct positioning of manufactured goods and facilitates control operations.
This innovative product revolutionizes the traditional approach to metal protection, definitively replacing old oiling and greasing systems with a more practical, economical and sustainable solution. PROPABOL VCI eliminates the need for post-opening pickling operations, providing manufactured goods immediately ready for use without oily residues to remove. It is completely recyclable, reduces operational costs and processing times, and offers superior protection even for delicate products that require both anti-corrosive preservation and mechanical cushioning. Available in rolls, formats and bags, it represents the ideal solution for companies seeking maximum efficiency with minimum environmental impact.
Problems solved by this product
It is very important to wear protective gloves as skin acidity can start oxidation of metal.
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.
Ferrous metals contain iron, for example steel, whilst non-ferrous metals do not contain iron, for example zinc, magnesium, and copper.
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.
Corrosion is a chemical reaction between a metal and its environment which results in a gradual destruction of metal and degradation of its properties.
Desiccant bags absorb humidity in the package, hence they reduce risk of oxidation. Still, to protect a material against corrosion, it is necessary to use a Propagroup VCI product as well.
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.
Some anticorrosive VCI products, like paper and certain films, work well in contact with the material to be protected, whereas VCI diffusers, for example, do work at a distance in order to saturate the inside of packaging with the VCI substance and protect the goods against corrosion attacks. VCI products are very often used together to protect metals both in contact and at a distance and to better preserve their quality over time.
There are different types of VCI depending on metal to protect.
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.
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.
