Professional-Grade Electrical Insulation

Scotch Super 88 is a premium 8.5-mil thick vinyl insulating tape built for electricians and maintenance crews who need reliable, all-weather performance. It carries UL 510 Listing and CSA C22.2 No. 197 certification, meeting professional code requirements for electrical installations and repairs.

Durable PVC Construction With Rubber Adhesive

The polyvinyl chloride backing resists abrasion, moisture, alkalies, acids and corrosion while remaining conformable down to minus 18°C. Its aggressive rubber adhesive creates a moisture-tight mechanical bond that protects conductors with minimum bulk in both indoor and outdoor environments.

Continuous 105°C Temperature Rating

Designed to perform continuously at ambient temperatures up to 105°C (220°F), this tape suits high-heat electrical systems where standard vinyl tapes would degrade. Buyers needing a lower temperature rating or a different width should verify specifications before purchase.
