From the Manufacturer

Scotch® Electrical Insulating Varnished Cambric Tape 2520 insulates and seals electrical components. Resistant to punctures and cut-through, the straight cut woven cotton cambric fabric maintains its insulating properties through normal wear and tear. A pressure-sensitive, non-corrosive rubber resin on the backing keeps the tape in position after application. Flexibility offers ease of application and moisture resistance protects electrical connections. Cambric tape is often used for insulating joints requiring rapid and clean re-entry such as motor leads and service drops. Operating temperature range is 32°F (0°C) to 220°F (105°C).

This 8-mil thick, yellow varnished electrical tape is rated for Class A 220°F (105°C) applications. Typical tensile strength is rated for 50 lbs/ inch.
