Here's what their product blurb says:<br><br>"Tape, Scotch(TM) Super 33+ Vinyl Electrical<br>Premium quality, 7 mil electrical insulating tape that applies well in broad temperature range. Flame-retardant, hot- and cold-weather resistant; resists UV rays, abrasion, moisture, alkalies, acids and corrosion.
