100 micron yellow polyethylene volatile corrosion inhibitor (VCI) film is mainly used for protecting metal parts and equipment from corrosion during storage or transportation. The yellow color of the film is used to distinguish it from regular polyethylene film and indicate that it contains VCI technology, which releases a chemical compound that creates a protective layer over the metal surfaces.

VCI films are used in various industries, including automotive, aerospace, military, and construction, among others. Some common applications of 100 micron yellow polyethylene VCI film are:

1. Metal Packaging:
The film is used to wrap metal parts and equipment, such as machinery, auto parts, or pipes, to protect them from corrosion during storage or transportation.

2. Export Packaging:
The film is used in export packaging to protect metal parts during long-distance shipping and handling.

3. Maintenance:
The film can be used to cover metal parts during maintenance or repair work to prevent corrosion while exposed to the elements.

4. Preservation:
The film can be used to protect metal parts during long-term storage, such as in storage facilities or warehouses.
VCI films are an effective and cost-efficient way to protect metal parts from corrosion without the need for oils, sprays, or coatings. The protective layer created by VCI technology is non-toxic, odorless, and does not leave any residue on the metal surface, making the removal of the film easy and safe.

VCI (volatile corrosion inhibitor) film is made of a combination of plastic polymers and corrosion inhibitors. The plastic polymers used in the film can be low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), or high-density polyethylene (HDPE), among others. These polymers provide strength, flexibility, and durability to the film.

The corrosion inhibitors used in the VCI film are a blend of different chemicals that release vapors or molecules that react with the metal surface and form a protective layer. The type and concentration of the corrosion inhibitors used in the film may vary depending on the specific application and the type of metal being protected.

Some common corrosion inhibitors used in VCI films include:

1. Amines:
These are organic molecules that release vapor or molecules that react with the metal surface and form a protective layer.

2. Nitrites:
These are chemical compounds that release a combination of nitrogen and oxygen ions that neutralize corrosive elements.

3. Phosphates:
These are compounds that react with metal surfaces to form a protective layer, which inhibits corrosion.

4. Benzotriazoles:
These are organic molecules that form a thin protective layer on metal surfaces, inhibiting corrosive ions from interacting with the metal.

The production of VCI films involves several steps. Here's a brief overview of the process:

1. Mixing of Plastic Resins:
The production process usually starts by mixing different plastic resins, such as LDPE, LLDPE, or HDPE, in a large mixing vat. The specific blend of plastic resins used will depend on the desired properties of the finished VCI film.

2. Addition of Corrosion Inhibitors:
Once the plastic resins are mixed, a specific blend of corrosion inhibitors is added to the mixture. The specific blend and concentration of corrosion inhibitors used will depend on the type of metal being protected and the desired level of corrosion protection.

3. Extrusion:
After adding the corrosion inhibitors, the plastic resin mixture is extruded through a die, which forms the VCI film into a continuous sheet or roll. The extrusion process involves heating and melting the plastic resins and corrosion inhibitors to form a homogenous mixture.

4. Cooling:
The extruded VCI film is then cooled, either by air or water cooling, to solidify the plastic resins and corrosion inhibitors into a stable film.

5. Slitting and Winding:
Once the VCI film is cooled and solidified, it is then slit and wound onto rolls of various widths and lengths, depending on the customer's requirements.

The production process of VCI films may involve additional steps or modifications, depending on the specific manufacturer and the desired properties of the finished film. However, the basic steps outlined above are common across most VCI film production processes.
