  • About glass cloth electrical tape

    Glass cloth insulating tapes offer high mechanical strength and resistance to high temperatures with excellent absorption of resins and varnishes. Our range of glass cloth tapes is flexible and conformable, with excellent cut-through and edge-tear resistance and are ideal for holding and strapping applications up to 200°C.

    Suggested applications for glass cloth insulating tapes include insulating electric and induction type furnace power supply leads and splicing silicone-covered glass wire. They are also ideal for applications such as wrapping bobbin wound coils, banding arbour wound coils, lead pad hold down and end turns. Utilising our range of converting capabilities we can offer glass cloth electrical tapes in custom width and length rolls or in custom shapes and final presentations.
