Scotch Varnished Cambric Tapes are made from straight-cut woven cotton cambric fabric. The fabric is oil primed and coated with a high-grade yellow electrical insulating varnish. Varnished cambric tapes are flexible, electrically insulating and moisture resistant with a smooth finish. Scotch Varnished Cambric Tape 2510 is yellow, non-adhesive coated and 7 mils thick. They are designed to perform continuously in temperatures up to 105°C (220°F) with excellent resistance to abrasion, puncture and cut-through.
FEATURES:
- Excellent dielectric strength.
- Electrical properties are stable up to 105°C.
- High puncture and cut-through resistance.
- Varnished cambric tapes are rated for Class A (105°C).
APPLICATIONS:
- For insulating joints requiring rapid and clean re-entry such as motor lead and service drop connections, heavy split- bolts in raceways and bus bar insulating. Use in areas where mechanical protection and puncture resistance is critical.
