PVC Coated Steel Tie Wire
Galvanized and plastic coated wire is used in manufacturing of binding wire, tie wire, plant support wire, meshes and fences.
PVC / plastic coated steel wire is processed with coating a layer of polyvinyl chloride or polyethylene on the surface of the core wires ( annealed wire, galvanized wire, stainless steel wire, Galfan wires, etc). The coating layer firmly bonded to the wire render the features of anti-aging, anti-corrosion, anti-cracking, long life and other characteristics.
Color Coating Materials: PVC / PE / Vinyl
PVC is the most popular powder for coating wires, as it is relatively low in cost, resilient, fire retardant and possesses good insulating properties. The PVC coating and the inside wire are firmly bonded together to offer a longer service life. High-density hard PVC (vinyl chloride) coating is applied against the corrosion of common acids and alkalis. The service life is up to 12 years, that is several times that of hot and cold galvanized iron wire. The colors can be customized according to customers needs.
The coating materials of PVC, PE, polyvinyl chloride, can be added with anti-UV, anti-aging additives to achieve enhanced properties.
Differences of PVC coating and PVC dipping
Plastic coating is a technical processing referring to the surface processing of the metal wire. The solid plastic is melt into liquid plastic under high temperature, then the metal wire material is put into plastic flow, it is taken out after certain time. Plastic Dipping is a process referring to the surface treatment on the finished steel wire mesh. Welded or woven wire mesh is treated with PVC dipping to achieve further protection from the weather and better anti-corrosion property.
In general, plastic coating mainly applies to the wire before further weaving or fabricating. The plastic dipping normally applies to the wire mesh processed with the steel wire.
Coated Wire Applications
1. Tie Wire / Binding Wire:
PVC / PE / Vinyl coated or painted wire is made in forms easy for binding and tying uses. The wire is popularly made into cut wire, cut and looped wire, or wound in coils, around sticks.
2. Hanger Wire
3. Mesh and Fencing Wire: For making of chain link fence, gabions and various meshes.
4. Vegetable and plant suppot wire
Main Parameters of Plastic Coated Wire
1, Material before coating:
stainless steel wire.
The wire gauge number, tensile strength, elongation, the amount of zinc and other parameters shall be pre-determined before the plastic coating processing. Average tensile strength for the PVC coated wire ranges from 350N/MM2-900N/MM2, elongation ranges from 8% -15%.
2, Coating Color:
Common colors are grass green (light green), dark green (dark green),Gray, White.
3, General Wire diameter with and without plastic coating:
Wire diameter before coating: 0.6mm-4.0mm (wire gauge BWG23-8)
Wire diameter with coating: 0.9mm-5.0mm (BWG20-7)
Plastic layer (0.4mm-1.5mm), wire diameter deviation (+0.05 mm/-0.05mm Ma
