Avantages
1) Corrosion & contamination protection
2) Outer layer provides excellent mechanical properties - puncture & tear strength
3) Provides multi-metal corrosion protection
4) Protected parts can be used immediately without cleaning or degreasing
Advantages of VCI over Oil and Grease
| Parameters | Oil and Grease | VCI Polyfilm |
| Suitability | Suitable only where metal items are to be protected. Not suitable if metal parts contain rubber or other material | Suitable for all sizes of products and for all situations |
| Method of application | To be applied by brush or hand which is time consuming | Packing or wrapping is easy |
| Drawback | Degreasing and removing oil is expensive and time consuming | No such problems |
| Moisture Barrier Properties | No surety unless secondary packing is done | Barrier of moisture and higher the thickness of film,greater the moisture properties. |
| Additional packing | Packed items require additional packing of plastic or jute | Additional packing not required if necessary thickness of flim can be increased |
| Cost/Benefits Analysis | Though cost of oil is not much,greasing and degreasing is expensive in terms of labour and time involved.Also the cost of secondary packaging. | Most cost effective corrosion protection method |
