Foils and foil laminates to film or paper provide EMI Shielding to cables.

Flame Barriers

Mica tapes provide excellent flame barriers and high temperature circuit integrity.

Dielectric Barriers

Polyimide films can provide high dielectric strengths up to 6000 volts/mil.


There are many high temperature papers used as separating tapes in high temperature cables.

Pyrodox® Mica Tapes

Pyrodox® Mica tapes are high temperature silicone bonded mica tapes providing excellent thermal performance in high temperature applications.


Kapton® provides high dielectric strength and thermal performance up to 240°C.


Nomex® provides 500 volt per mil dielectric strength with thermal performance up to 220°C.

Traverse Packs

Traverse packaging can provide lengths 8 to 10 times longer than are available in pads. They are particularly helpful on narrow widths where pads are impractical.

Flat Pads

Flat pads are popular when slit widths are greater than 1".

2-Ply Traverse Packs

2-ply traverse packages allow the taper to balance tension on fine wire to prevent cable occelation at the wrapping location.
