Scotch® Super 33+ Vinyl Electrical Tape is a premium grade, 0.178mm thick, all-weather vinyl insulating tape. It is designed to perform continuously in a temperature ambient of up to 105°C (220°F). The tape is conformable for cold weather application down to –18° (0°F). It has excellent resistance to abrasion, moisture, alkalies, acids, corrosion and varying weather conditions (including ultraviolet exposure). The combination of elastic backing and aggressive adhesive provides moisture-tight electrical and mechanical protection with minimum bulk. Super 33+ is an Underwriters’ Laboratories Listed and Canadian Standards Association Certified “Insulating Tape”.
Scotch Super 33+ Vinyl Electrical Tape is a premium‑grade, 0.178 mm thick PVC insulating tape designed for continuous use from –18 °C (0 °F) up to 105 °C (221 °F). It offers excellent resistance to abrasion, moisture, chemicals and UV exposure, and is UL 510 listed for flame‑retardant performance.
The sheet lists typical physical properties such as adhesion, breaking strength, elongation, dielectric breakdown (5 kV/mm), and a maximum telescoping of 2.5 mm at 50 °C. Installation guidance covers half‑lapped winding, tension control, and recommended use for 600 V splices and high‑voltage cable repairs. Availability includes standard roll sizes from 9.5 mm to 50 mm wide.
