Thickness 0.18mm Two Sides Copolymer Coated Copper Tape For Cable Armouring, Shielding
Double Side copolymer coated copper tape ,which also named as copolymer laminated copper tape, copper copolymer lamination tape, EAA-AL-EAA lamination copper tape, EVA copolymer coated copper tape with two sides, Polyster coated copper tape with two sides, plastic coated copper tape, It applies for medium and high voltage power cables as a shield/moisture barrier as a moisture/ chemical barrier for cable core, it consists of a copper tape coated on double side with a special ethylene copolymer color-coded green.
The main advantages of our products includes: Firstly, Copolymer coated on the copper tape is highly heated EAA with good sealability, Comparing with normal PE, EAA has lower bonding temperature and higher heat sealability, which make longitudinal winding technique more simply and convenient in cable production. Secondly, our product has low coefficient of friction, which is lower than 30-50% of same factories. Using this low coefficient of friction products, copolymer coated metal tape has small deformation and low mechanical losses in production, which can improve the stability of fiber optic cable and service life.Copolymer coated copper tape applies for medium and high voltage power cables as a layer of shield/moisture barrier for cable core, if consists of copper tape coated with single side copolymer. The coating forms a strong moisture-resistant bond to copper substrate, also form strong polymeric bonds to zero halogen, polyethylene and chlorinated polyethylene jacketing resins during jacket extrusion process.
