What material is VCI anti-rust plastic film made of?
The base material is LDPE, which is low-density polyethylene. During the film blowing process, VCI masterbatch, color masterbatch, and additives are added. The VCI masterbatch is a volatile corrosion inhibitor (VCI) masterbatch that provides rust prevention. It primarily works by volatilizing and protecting the metal surface. 1, VCI stands for volatile corrosion inhibitor, and VCI film is a vapor phase corrosion inhibitor film. Its composition is actually quite simple,

Research progress and application of gas-phase corrosion inhibitors
Vapor phase corrosion inhibitors (VPCI) are a new type of rust-preventing material that emerged in the 1940s. Initially used for protecting military equipment, VPCI has seen extensive research and rapid development due to its ease of use, high efficiency, shape-independent application, and long protection period. It has become one of the primary materials for preventing atmospheric corrosion of metals. A VPCI is a blend of one or more chemical substances. Simply placing it near a metal object allows its vapors or sublimated components to reach the metal surface, forming a protective film that prevents corrosion. Volatility is generally measured by saturated vapor pressure. The saturated vapor pressure of VPCI...

Development and Sustainable Development Discussion of Vapor Phase Corrosion Inhibiting Plastic Films
The deterioration and destruction of metallic materials due to chemical or electrochemical reactions with their surrounding environment is called corrosion. According to the reaction mechanism of metal corrosion, corrosion can be divided into electrochemical corrosion and chemical corrosion. Electrochemical corrosion refers to the destruction caused by electrochemical reactions between the metal surface and an ionically conductive medium; chemical corrosion refers to the destruction caused by a purely chemical reaction between the metal surface and a non-electrolyte. Among them, electrochemical corrosion is the most common and widespread type of corrosion, because as long as there is condensed water in the environmental medium, metal corrosion will occur in the form of electrochemical corrosion.
