Single or double-sided EAA coating, high peel strength, excellent moisture barrier. Custom widths & thicknesses available. Inquiry Now for specifications.

Copolymer Coated Copper Tape

Copolymer Coated Copper Tape (also known as EAA Coated Copper Tape or Copolymer Copper Shielding Tape) is a premium shielding and moisture-barrier material designed for medium- and high-voltage power cables. It consists of a high-conductivity copper tape coated on one or both sides with a specialized ethylene copolymer (EAA) layer, color-coded green for easy identification. This advanced composite tape provides excellent electromagnetic shielding, superior moisture and chemical resistance, and strong bonding to cable jacketing resins, making it ideal for “bonded jacket” or laminated sheath constructions.

Copolymer Coated Steel Tape For Cable Armoring

Copolymer Coated Steel Tape (also known as EAA Coated Steel Tape or Copolymer Steel Shielding Tape) is a high-performance composite material designed for armoring, shielding, and moisture protection in communication optical cables, shielding cables, and waterproof cables. It consists of a high-quality low-carbon steel tape coated on one or both sides with an adherent ethylene copolymer (EAA) layer, delivering exceptional mechanical strength, corrosion resistance, and reliable bonding to cable jacketing materials.

Copper Tape For Cable

High-purity (≥99.9%) soft-annealed ETP copper tape engineered for metallic shielding in medium- and high-voltage power cables, XLPE-insulated cables, control cables, and communication cables. Delivers near-100% IACS conductivity, excellent formability for high-speed helical or longitudinal wrapping, superior EMI/RFI attenuation, and reliable fault-current carrying capacity. Custom thicknesses, widths, and optional tinned or bondable versions available for long-term cable integrity and EMC compliance.

Galvanized Steel Tape for Cable and Wire Armouring

Premium hot-dip galvanized steel tape engineered for cable armoring. Manufactured from high-quality cold-rolled carbon steel (Q195/Q235/SPCC) with a uniform zinc coating (80–140 g/m² or higher). Delivers excellent corrosion resistance, high compressive strength, and superior processability on high-speed armoring lines. Widely used as Steel Tape Armor (STA) in medium- and high-voltage power cables for underground, direct-buried, aerial, and harsh-environment installations.

Halogen Free Flame Retardant PP Fibrillated Filler Yarn | HFFR Cable Filler Material

Halogen Free Flame Retardant PP Fibrillated Filler Yarn, also known as HFFR PP Filler Yarn (Not Twist), is a high-performance, environmentally friendly cable filler material produced from premium polypropylene with advanced halogen-free flame retardant additives. Through a specialized fibrillation process, it forms a strong mesh structure that provides excellent filling, rounding, and mechanical reinforcement for cables while delivering superior flame retardancy and low smoke emission. This non-twisted fibrillated yarn is the ideal choice for high-grade flame-retardant cables requiring compliance with strict environmental and fire-safety standards.

Mica Tape for Fire Resistant Cables

Premium mica tape for fire-resistant cables engineered from phlogopite, muscovite or synthetic mica paper, reinforced with alkali-free glass cloth and high-temperature silicone resin. Maintains circuit integrity up to 950–1050°C for 90–180 minutes, complying with IEC 60331 and BS 6387 CWZ. Ideal for power, control, marine, and emergency system cables. Zero halogen, high tensile strength, customizable widths and thicknesses. Reliable quality for long-term safety-critical applications.

PET Polyester Tape (Mylar Tape)

Available in 12–100 μm thickness, multiple colors, and custom slit widths. RoHS/REACH compliant. Inquiry Now for samples and technical data.

Water Blocking & Absorbing Yarn

Water Blocking Yarn, also known as Water Swellable Yarn, is a high-performance water-blocking material widely used in modern cable manufacturing. It combines high-strength industrial polyester (or nylon) filaments with superabsorbent polymers (SAP) and specialized adhesives. When exposed to water, the yarn rapidly absorbs moisture and expands to form a dense gel that effectively seals cable interstices, preventing longitudinal water penetration along the cable core.

Water Blocking Powder

Water Blocking Powder is a high-performance superabsorbent polymer (SAP) based on sodium polyacrylate. This advanced macromolecule water-absorbent resin features a unique three-dimensional network structure and abundant hydrophilic groups, delivering exceptional water absorption capacity, strong water retention, and rapid expansion. It is specifically engineered for longitudinal water blocking in power cables, communication cables, optical fiber cables, and other stranded conductor applications.
