3M Scotch Electrical Tapes

3M Scotch 2510 & 2520 Tape

 

3M Scotch Varnished Cambric Tapes are made from straight-cut woven cotton cambric fabric which is oil primed and coated with a high-grade yellow electrical insulating varnish.

• 3M Scotch 2510 tape is yellow, non-adhesive coated and 7 mils thick 
• 3M Scotch 2520 tape is yellow with a pressure-sensitive adhesive and 8 mils thick

The Varnished Cambric Tapes are designed to perform continuously in temperatures up to 105°C (220°F) with excellent resistance to abrasion, puncture and cut-through. The adhesive on 2520 tape holds the tape in position after application. 

Benefits	Excellent dielectric strength Electrical properties are stable up to 105°C High puncture and cut-through resistance Varnish cambric tapes are rated for Class A (105°C) Non-corrosive adhesive on 2520 tape. Adhesive holds film in position until the jacket is applied
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
