Vinyl Electrical Tape
Data Sheet October 2014
Description
Scotch® Super 33+™ Vinyl Electrical Tape is a premium grade, 7 mil thick, all-weather
vinyl-insulating tape. It is designed to perform continuously in ambient temperatures up
to 105°C (220°F). The tape is co nformable for cold weather application down to -18°C
(0°F). It has excellent resi stance to abrasion, moisture, alkalies, acids, corrosion and
varying weather conditions (including ultraviolet exposure). The combination of elastic
backing and aggressive adhesive provi des moisture-tight electri cal and mechanical
protection with minimum bulk. Scotch® Super 33+™ Vinyl Electrical Tape is UL Listed
and is a Canadian Standards Association (CSA) Certified “Insulating Tape.”

Specifications Scotch® Super 33+™ Viny l Electrical Tape is based on polyvinyl chloride (PVC) and/or
its copolymers and has a rubber-based, pressure-sensitive adhesive. The tape shall be
7 mils thick, and be UL Listed and marked per UL Standard 510 as “Flame Retardant,
Cold and Sunlight Resistan t.” The tape must be applicable at temperatures rang i ng from
0°F through 100°F (-18°C t hrough 38°C) without loss of physical properties. The tape
shall be classified for use in both indoor and outdoor environments. The tape shall be
compatible with synthetic cable insulations, jackets and splicing compounds. The tape
will remain stable and will not telescop e more than 0.1 inches when maintained at
temperatures below 120°F (50°C).

Specification:
Primary electrical insulatio n (branch wiring in wet or dry locations): All splices for 600 volt
wire rated 105°C (220°F) and below shall be insulated with a minimum of two half-lapped
layers of Scotch® Super 33+™ Vinyl Electrical Tape. All connectors having irregular
surfaces shall be padded with 3M™ Scotchfil™ Electrical Insulation Putty or Scotch®
Linerless Rubber Splicing Tape 130C prior to insulating with Scot ch® Super 33+™ Vinyl
Electrical Tape.
Mechanical protection (o uter jacketing): All rubber and thermopla stic insulating high
voltage power cable tape splices and repairs shall be overwrapped with at least two half-
lapped layers of Scotch® Super 33+™ Vinyl Electrical Tape.
Installation
Techniques: Scotch® Super 33+™ Vinyl Electrical Tape shall be applied in half-lappe d 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, the
tape shall be wrapped beyond the end of the wires an d 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 the tape with no tensi on on the last
wrap to prevent flagging.
