Specification – 3M Scotch 22 Vinyl Electrical Tape

Scotch Tape 22, manufactured by 3M Electrical, is based on polyvinyl chloride (PVC) and/or its copolymers, and has a rubber-based, pressure-sensitive adhesive. The 3M Scotch tape shall be 10 mils thick, and be UL Listed and marked per UL Standard 510 as “Flame-Retardant and Cold-Resistant.” The Scotch tape must be applied at temperatures ranging from 15°F through 100°F (-10°C through 38°C), without loss of physical properties. The Scotch 22 be classified for use in both indoor and outdoor environments. The tape shall be compatible with synthetic cable insulations, jackets and splicing compounds. Vinyl tape will remain stable and will not telescope more than 0.1 inches when maintained at temperatures below 120°F (50°C).

3M SCOTCH 22 TAPE – Installation Techniques

• Scotch 22 Tape should be applied in half-lapped layers with sufficient tension to produce a uniform wind (for most applications this tension will reduce the tape’s width to approximately 5/8 of its original width)
• On pigtail splices and joints, the 3M tape shall be wrapped beyond the end of the wires and then folded back, leaving a protective cushion to resist cut-through
• Wrap tape up-hill, taping from a smaller diameter surface to a larger diameter surface
• Apply 3M Scotch 22 tape with no tension on the last wrap to prevent flagging

3M Scotch Tapes, including Scotch 22 are preferred by global electric utilities for their high performance, specification and reliability compared to unbranded poor electrical quality tapes prone to degradation, flagging and failure.
