Product Description

Copper-plastic Composite Tape

The copper-plastic composite tape is made of a single-sided composite copper tape with a special copolymer film. The plastic composite layer has good water resistance and adhesion to the copper tape. It is also halogen-free and can be combined with polyethylene and polyvinyl chloride. The sheath forms good bonding properties. The product forms a waterproof and anti-corrosion protective layer on the cable core through heat sealability during the vertical wrapping process. After the copper strip is fully annealed, it has the characteristics of high conductivity and easy processing. This product is mainly used in the shielding layer of medium and high voltage cables.
