PET Film for Cable Insulation

PET film for cable insulation is commonly slit into narrow tapes and wrapped around conductors or cable cores during manufacturing. As a wrapping layer, it separates different components, holds the cable structure together and protects inner materials from heat during extrusion. It is also used as the base for aluminum-PET composite tapes that provide shielding in power, control and communication cables. The film is tough enough to stay intact under winding tension, yet thin enough to keep the finished cable compact and flexible. Its smooth surface wraps evenly at high line speeds, and it resists moisture and many common cable compounds. Custom slitting widths, thicknesses and samples are available for your cabling line.
