4 Big Mistakes Companies Make When Selecting VCI for Their Metal Parts
There are many choices you must consider when it comes to preventing loss due to rust on your valuable metal parts. You may have noticed that across the industry a VCI bag’s ability to prevent rust varies widely between brands. Not all VCI technology is the same. While you may think rust is a natural consequence of metal manufacturing, the threat of rust has been successfully eliminated for some of the largest metal parts manufacturers in the industry. Below are a few things you need to consider when selecting the right VCI for your company.
1. Large Metal Parts Need a Higher Vapor Pressure Many VCI brands still use sodium nitrite as the active ingredient in their VCI formulation. Sodium nitrite is more cost effective, but it contains very low vapor pressure, which causes the VCI particles to stay in close proximity to the VCI material and keeps them from migrating deep within the packaging environment. This often leaves areas where the metal part isn’t touching the bag unprotected – this is especially the case with larger or more complex metal parts. 2. Older VCI Technology Could be Harmful to Your Employees Sodium nitrite and secondary amines are chemicals that have been banned by several other countries because of the threat they pose to human health and the environment, but they are still being used by a lot of VCI brands. Although nitrites aren’t independently harmful, when used in packaging, amines and nitrites can combine to form nitrosamines. Nitrosamines are known carcinogens, and when inhaled can cause cancers of the liver, bladder, and stomach. 3. Cast Iron Parts Require a Higher Concentration of VCI Because cast iron contains greater than 2% carbon, it is more susceptible to corrosion than steel, copper and aluminum. Therefore, a higher concentration of VCI is necessary to protect your metal castings from rust. At Green Packaging, our Rust Guard Premium™ Cast VCI bags contain the highest concentrated levels of VCI on the market. 4.
