Benefits of Vapor Corrosion Inhibitors (VCI) Packaging

3 cost scientific studies are offered that supported decisions by business companies to change to Vapor Corrosion Inhibitor (VCI) presentation from standard methods: oil coatings, and also desiccant in barrier box. These legacy techniques continue to be prevalent in military applications wherein these cost versions might be helpful references. The scientific studies show cost reductions of thirty five % to more than fifty % for situations of long-term storage as well as seashore shipment of mechanical, electronic and electrical equipment. 2 of the experiments supported choices to replace oil oxidation prevention coatings on inter plant marine shipments of “Completely Knocked Down” (CKD) ferrous automobile car engine components. These 2 cases represent the wide trend which drove rapid company sales in techniques for worldwide shipments from “wet” (oiled) to “dry” components & subassemblies shielded with VCI product packaging. The 3rd price analysis supported a specification choice to deliver container lots of electronic control medicine cabinet along with other electromechanicai modules for a turnkey factory. Packaging used VCI film mixed with VCI vapor capsules over desiccants placed in three layer barrier box (MIL-B-131H Type one Class one). Other critical decision variables included improved corrosion protection, process yields, reliability and quality, environmental compliance, logistics, enhanced office wellness and security.
INTRODUCTION

Corrosion protection of metallic surfaces is still a costly and pervasive issue for long-term storage and also shipment of military equipment and parts ~, especially when areas should be ready, uncorroded, and clean to work with straight from the program or even shipping container. Vapor corrosion inhibitor materials were made aproximatelly 2 decades ago two in different types of polyolefin plastics that give off volatile molecules over extended time periods. This fundamental creation of processes and formulations for building VCI plastic-made materials provided the foundation for the ongoing development within this technology, such as polyethylene films, tubes, vapor capsules, foams, bags, rods and molded containers for a growing variety of uses. The effectiveness of theirs and also cost benefits in protecting systems and parts from oxidation have resulted in replacing of desiccants and oil coatings in business applications who parallel military usage. Some these apps vary from other vehicle and engine components components, such as for instance those shown in figures one to three, to electronic and electrical equipment and components, shown in figures four to six, which have a bunch of critical-to-function metal surfaces which directly affect reliability, process yields, readiness, along with other steps of the price of corrosion.

Oils and some other coatings are not an optimum choice for other factors and cost. Desiccants are one more legacy materials applied to the perception that they might guard clean parts. Without well sealed enclosures that maintain very small moisture transmission, they start to be ineffective after a couple of weeks or days.

The military segment lags the manufacturing segment in replacing history techniques, like petroleum coatings, desiccants and barrier wrapping, with VCI substances. This paper provides 3 cases of cost analyses which were created for decisions by businesses that changed to VCI presentation for safeguarding ocean shipments of systems and parts. These cost analyses augmented different critical decision variables which are mentioned however, not detailed in the business research, such as enhanced efficiency, process yields, reliability and quality and intangible factors like much better safety and work environment.
