It is a superior multilayered high strength woven core metal wrap for protecting flat sheet and coiled metal. Duramet is designed to withstand demanding environment, handling, and transport applications. Duramet will ensure that your high grade metal arrives at its destination looking steel mill fresh!
Promet™ combines the high strength of a multilayered woven wrap with a premium grade kraft paper base layer. This blend of woven poly and laminated kraft makes Promet the ideal solution for protecting your flat sheet & coiled steel in areas with higher relative humidity or large temperature fluctuations.
is a 70 gsm specially matured Kraft paper, one side activated with 10-12 gsm of VCI chemicals (Volatile Corrosion Inhibitors ), laminated & reinforced with waterproof woven fabric. It is suitable for packing of heavy metals, small components, big machines from corrosion & tarnishing.
VCI paper types:
1. KRAFT PAPER
Structure: VCI+kraft paper
For dry production of metal
2. POLY COATED KRAFT PAPER
Structure: VCI+kraft paper+PE film
Havy strength due to poly coated
- 3. LAMINATED HDPE FABRIC KRAFT PAPER
Structure: VCI+kraft paper+PE film+PE cloth
It is available up to 3000mm in width seamless i.e. without joint. It provides two-pronged protection:
1. Physical protection with cost effective, optimal, mechanical structure.
2. Superior VCI chemical protection developed with focused research. CORE ELEMENTS:
VCI Paper provides an extremely dry method of protection. It protects bare metals both through direct contact and vapor action. The high-tech VCI chemicals have a property of evaporating into the surrounding enclosure. The released vapor deposits on the metal surface and forms a protective mono-ionic layer, which provides protection to the packed parts from corrosion. It thus enables effective and long-term protection of ferrous metals against corrosion under adverse conditions including contaminants in air such as hydrogen sulphide, sulphur dioxide, ammonia or acid rain. VCI vapors easily migrate to hard to reach areas like drilled holes, crevices etc. and give effective protection.
METALS PROTECTED
Ferrous metals like cold rolled steel coils/Sheets, Wires, Steel pipes & Tubes, Crank Shafts, Piston Rings, Machined, Parts etc.
FEATURES
CORROSION is a destructive chemical process; most often it is the conversion of a metal to its oxide, for example, the corrosion of iron by oxygen and water to produce iron oxides (i.e., rust).
VCI paper carries a high load of specially engineered rust preventing chemicals (VCI's). These chemicals dissociate into Anions and Cations with moisture as an electrolyte. These Anions and Cations associate with anodic and cathodic reactive areas respectively on the metal surface forming mono-ionic protective layer, making it inert for any further reaction such as oxidation/rusting. Any loss of ions is replenished through further condensation of vapour ensuring continuous protection. It protects metals strongly through direct contact as well as vapor action.
BENEFITS
