  • About polyester electrical tape

    We offer a range of polyester electrical tapes for insulating applications requiring thin and durable materials with high dielectric strength. Applications include end turns, inner layer insulation and wrapping capacitors, wire harnesses, transformers, shaded pole motors and fractional horsepower motors. Utilising our range of converting capabilities we can offer polyester insulating tapes in custom width and length rolls or in custom shapes and final presentations.

    Polyester electrical tape characteristics:

    • Chemical, solvent and moisture resistant
    • Flame retardant, UL rated products
    • Single or double coated
    • Printable
    • Excellent flagging resistance
    • High edge-tear resistance and high puncture and abrasion resistance
    • Available in a range of colours and thicknesses
    • Available with acrylic or thermosetting rubber adhesives
