VCI stands for volatile corrosion inhibitor and VPI stands for volatile protective inhibitor. VCI or VPI are papers and films treated with engineered chemicals that safely prevent corrosion on protected metals. The chemicals in the VCI or VPI products are volatile.
When metals are wrapped or packaged in VCI or VPI the chemicals volatize in the packaging environment and form a protective molecular layer on the surface of the metal. This protective layer prevents salt, dirt, oxygen and other materials from depositing on the metal and causing corrosion.
