  • About composite film tape

    Composite film tape combines the high dielectric strength and edge-tear resistance of polyester film and nonwoven polyester for a conformable product with excellent puncture resistance and electrical properties.

    Composite insulating films are excellent for general purpose insulation and are suggested for use in stick-wound coils/transformers and in bobbin-wound coils for banding, anchoring and insulating. Other applications include protecting start wires, leads, terminal strips, insulation paper, end turns and connections in motors and transformers.

    Utilising our range of converting capabilities we can offer composite film insulating tapes in custom width and length rolls or in custom shapes and final presentations.

    Composite film tape characteristics:

    • Available with an aggressive rubber resin or solvent-resistant acrylic adhesive
    • High dielectric strength
    • Available in a range of thicknesses
    • Puncture resistance
