Rolled Copper Foil Polyester Composite Tape
CU-PET Tape is a flexible composite shielding material, produced by laminating rolled copper foil and PET (polyester) film, then going through precise drying and slitting procedures. The rolled copper foil delivers excellent electrical conductivity and high-efficiency EMI/RFI shielding to block external signal interference. The PET film provides mechanical reinforcement, tensile strength and insulation protection, preventing copper foil from oxidation and mechanical damage during cable manufacturing and service life.
Thanks to its reliable shielding capability and stable physical properties, CU-PET tape is extensively used for shielding construction of communication cables, data cables, coaxial cables, signal cables and other wires requiring high anti-interference performance.
