Copper/PTFE Shielding Tape

Polytetrafluoroethylene film laminated copper foil

Copper/PTFE Shielding Tape has excellent flexibility and utilizes high strength copper foil laminated with PTFE for superior shielding and insulation. Copper/PTFE shielding tapes are suitable for industrial and electrical applications, including EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) shielding. PTFE film laminated copper foils for cable shielding can withstand common sources of degradation, including moisture, UV exposure, and various chemicals. They are commonly used for reflecting, wrapping, shielding, sealing and other applications. In addition, shielding tapes are thermally conductive, which improves heating/cooling efficiency. Copper/PTFE shielding tapes are made from polymer compounds derived from polytetrafluoroethylene and offer excellent chemical stability, corrosion resistance, sealing properties, high lubricity, electrical insulation and good aging resistance.

Features

Applications

PTFE film tapes are used as non-stick coatings due to their high heat resistance and non-stick properties, and are often suitable for frying pans or other types of cookware. Because of its non-conductive properties, PTFE film tape is also ideal as an insulating material for electrical applications.

Shielding laminates are often categorized based on the type of matrix material used. The four main categories of shielding laminates are Polymer Matrix Composites (PMC), Metal Matrix Composites (MMC), Ceramic Matrix Composites (CMC) and Carbon Matrix Composites (CAMC).

Metal shielding laminates are produced by continuously bonding two thin metal sheets or natural metal films to one side of a thermoplastic core. These cores form sheets that are lighter in weight, easy to fabricate, flat and durable.
 
Slightly oxidized copper foil surfaces can be cleaned using an alcohol sponge. However, for long-term or extensive oxidation, a sulfuric acid solution is required to clean and remove oxidation.
