VCI Resin/Masterbatch (excluding nitrite), is a kind of environmental-friendly product. It contains no nitrite and heavy metals, fully conforms to SGS, RoHS Reach. And it does not produce harmful substances in the process of the production of antirust film, and it is green eco-friendly product indeed.

The safe VCI resin (excluding nitrite) is a basic function masterbatch to produce VCI film, which is made from LDPE,LLDPE and VCI materials. It is concentrated to the Low density polyethylene masterbatch during in the processing of raw materials mixed . Its main components are composed of vapor phase corrosion inhibitor and various additives. VCI masterbatch is mixed according to a certain proportion in LDPE and LLDPE masterbatch, and it need to be fully mixed and dispersed, and then blowing to the film by the machine. In the processing of production, the heating temperature can not exceed 190 DEG in all areas of blow moulding machine.
Generally, the proportion of mixed vci masterbatch to PE is 1:50.However,it should refer to the thickness of the film or application and requested shelf life. The life of protection anticipated by film containing VCI is 2 years when extruded with ideal processing guideline. We recommend that an evaluation is made in every single case to confirm that the anticorrosion effect is fulfilling the demands. It is also recommended to conduct the field tests before regular production.
The characteristics of VCI masterbatch is added into the plastic film ,and VCI contained in the film begins to sublimate and volatilize the antirust particles which diffuse and penetrate into the surfaces of the articles for antirust and adhere on them to form a compact protection film with the thickness of monomolecular to avoid the surfaces of the articles for antirust in contact with all factors inducing corrosion, thus the corrosion is effectively prevented. The vci particles are in good disparity, no crystal point and non-toxic.

Shelf life:2 years. The VCI masterbatch series can be increased other functions such as antistastic, smooth, increase transparency, etc.
Applicable Metals:
Steel, copper, brass, bronze, plated metal, zinc and its alloy, chrome and its alloy, cadmium and its alloy, nickel and its alloy, tin and its alloy, and other metal materials and their products

Attention matters in application:
1. The addition ratio of the product is 1:50
2. The vci masterbatch and PE material should be mixed evenly.
3. Attention to the temperature control when blowing VCI film
4. Attention to the moisture and rainy days.
5. The VCI film can add the color masterbatch according to the customer’s requirement, however, the color masterbatch which we do not recommend maybe affect the untirust effect.
6. For the rest of the VCI masterbatch ,it need to be sealed promptly, and kept in a cool, dry, and ventilated place, away from sunshine and no contact with sources of ignition and corrosive materials.
Custody and storage:
With sealed package, it shall be kept in a cool, dry ,and ventilated place, away from sunshine and no contact with sources of ignition and corrosive materials. Storage period in the original package is 12 months, opened bags should be closed very tighty after use for further storage.
Remarks:
Since VCI film prevents metals from rusting by means of the continuous and adequate VCI gasified antirust particles volatilized from VCI contained in the film, thin film means less VCI content which may influence the usage effects of the product. Therefore, on the basis of our practical experience, the recommended standard thickness of the VCI film made from VCI antirust resin shall beu100um (0.10mm, commonly referred to as 10 decimillimeter). We recommend that only virgin masterbach be used to the production of the VCI film. If nessary, modifications are made to provide for any additional properties needed such as UV, Anti-Stastic, etc.
