SPECIFICATION FOR PVC COATED WIRE

1.PVC COATING

A coating on wire and wire products made from organic coating material consisting  primarily of vinyl chloride homopolymer or copolymer obtained by various polymerization process. The coating material may also contain plasticisers, pigments, stabilizers, lubricants and other substances. The coating material is in the form of powder or granules.

2. Methods of application and classes of PVC coationgs.

The organic coationg material shall be applied from granules by extrusion or from powders by the fluidized bed method or powder spraying.

PVC coatings are classified on the basis of their method of application:

Class1:wire with a PVC coating applied by direct extrusion onto the base wire. This process usually produces a non-adherent tube covering the wire.

Class2:wire with PVC coating applied by extrusion and made to adhere to the base wire by the use of a primer which may be thermally cured or by the use of organic glues.

Class3:PVC powder material applied by thermal fusion or electrostatic spray which is adherent to the base wire.

Class4:wire that has been pretreated with a primer, thermally cured and then covered with a PVC powder applied thermally or electrostatically to give an adherent coating.
