3M Super 88 Vinyl Electrical Tape

3M Super 88

The final layer of a three-tape splice can be made up of one of two possible tapes. While 3M Super 33+ is the most commonly used tape, 3M Super 88 tape is a more robust option than 33+. Super 33+ has a 7-mil thickness compared to 8.5 mil with Super 88. Made with a Polyvinyl Chloride (PVC) outer layer and pressure sensitive rubber based adhesive, the tape can provide a moisture free protection barrier for electrical and mechanical protection. Super 88 can be used indoors and outdoors and is rated for all weather use. Super 88 is UL listed (UL 510 standard “Insulating Tape”) and CSA certified (Standard C22.2 No 197-M1983 “PVC Insulating Tape”).

  • 8.5 mil thickness
  • Primary electrical insulation for 600V and lower applications
  • All weather application
  • Application Temperature of -18°C to 38°C (0°F to 100°F)
  • Maximum operating temperature of 105°C (220°F)
When completing a three-tape splice, the Super 88 is the last layer to be applied. Starting from the outer edge of the splice, go around the cable with a 50% overlap until the entire spliced area is covered. If additional protection is required a second layer can be applied. 

When ordering 3M Super 88 tape, please indicate the number of rolls required to complete the task. Also, please keep in mind if you may require 3M Scothfil Putty or 3M 130C rubber tape to complete the splice.
