In high-performance cable manufacturing, combining superior mechanical armoring with reliable moisture and chemical protection is critical for long-term durability in demanding environments. Copolymer Coated Steel Tape<\/strong><\/a> (also known as EAA Coated Steel Tape or Copolymer Steel Shielding Tape) is a premium composite material engineered specifically for armoring, shielding, and environmental barrier applications in optical fiber cables, communication cables, shielding cables, and waterproof power cables.<\/p>\n

This advanced tape consists of a high-quality low-carbon electrolytic chrome-coated steel (ECCS) base uniformly coated on one or both sides with a specialized ethylene acrylic acid (EAA) copolymer layer. The result is a semi-flexible yet robust armor that delivers exceptional mechanical strength, cathodic corrosion protection, and permanent bonding to common jacketing resins (LDPE, LLDPE, MDPE, HDPE, or zero-halogen compounds) \u2014 enabling reliable \u201cbonded jacket\u201d or laminated sheath constructions.<\/p>\n

As a specialist B2B supplier of complete cable materials and technical solutions with decades of global project experience, we recognize copolymer coated steel tape as the preferred choice for manufacturers requiring combined armor and moisture barrier performance in outdoor, underground, submarine, and industrial installations.<\/p>\n

\"Copolymer<\/p>\n

Composition & Engineered Structure<\/h2>\n

The tape is built on a precision-engineered base:<\/p>\n

    \n
  • Low-carbon electronic chrome-coated steel (ECCS)<\/strong>: Thickness 0.15 mm or 0.20 mm, tempered to T2 condition for optimal formability and fabrication characteristics.<\/li>\n
  • rev\u00eatement en copolym\u00e8re EAA<\/strong>: Approximately 0.05 mm per side (one or both sides), often color-coded green or white for easy identification during production.<\/li>\n<\/ul>\n

    The EAA layer metallurgically bonds to the steel substrate and exhibits excellent chemical compatibility with extruded jackets, forming a permanent, non-delaminating interface during high-speed cabling processes. This structure combines the high tensile strength of steel with the superior adhesion, moisture resistance, and processability of the copolymer.<\/p>\n

    Principaux avantages techniques et gains de performance<\/h3>\n

    Robust Mechanical Protection<\/strong><\/p>\n

      \n
    • Tensile strength: \u2265300 MPa (typically 310\u2013420 MPa)<\/li>\n
    • Elongation at break: \u226520%<\/li>\n<\/ul>\n

      These properties provide excellent resistance to crushing, impact, rodent attack, and external pressure while maintaining sufficient flexibility for helical or longitudinal wrapping on high-speed armoring lines.<\/p>\n

      Barri\u00e8re sup\u00e9rieure contre l'humidit\u00e9 et les produits chimiques<\/strong><\/p>\n

        \n
      • Peel strength: \u22656.13 N\/cm<\/li>\n
      • R\u00e9sistance au thermoscellage : \u2265 17,5 N\/cm<\/li>\n<\/ul>\n

        The EAA copolymer creates a high-integrity waterproof shield that prevents longitudinal and radial water ingress, making it ideal for waterproof and underground cable designs.<\/p>\n

        Outstanding Corrosion Resistance<\/strong> Achieves 7e ann\u00e9e<\/strong> performance with no delamination after 168 hours at 68\u00b0C in filler\/flood or water resistance tests \u2014 significantly extending service life in moist, saline, or chemically aggressive environments.<\/p>\n

        Electrical & Dielectric Integrity<\/strong> Two-side coated versions exhibit Aucune rupture di\u00e9lectrique \u00e0 1 kV CC<\/strong>, preserving full insulation performance across the sheath interface.<\/p>\n

        High-Speed Processing Compatibility<\/strong> Excellent formability and low bonding temperature simplify longitudinal or helical application, reducing manufacturing defects and improving overall production efficiency.<\/p>\n

        Principales applications dans les syst\u00e8mes de c\u00e2bles<\/h3>\n

        Copolymer Coated Steel Tape is widely specified for:<\/p>\n

          \n
        • C\u00e2bles \u00e0 fibres optiques<\/strong>: Primary armoring layer providing rodent protection, crush resistance, and moisture barrier in outdoor, submarine, and direct-buried installations.<\/li>\n
        • Communication & Shielding Cables<\/strong>: Combined mechanical armor and EMI\/RFI shielding in telecommunication and data cables.<\/li>\n
        • Waterproof Power Cables<\/strong>: Longitudinal or helical wrapping in MV\/HV cables requiring integrated armor and environmental protection.<\/li>\n
        • C\u00e2bles sp\u00e9ciaux<\/strong>: Underground, aerial, and industrial control cables exposed to mechanical stress and harsh conditions.<\/li>\n<\/ul>\n

          Its semi-flexible design makes it particularly suitable for fiber optic cables where lightweight yet strong protection is essential.<\/p>\n
