Electrical tape 3M 471BL50

The 3M 471BL50 electrical tape is a blue silicone/rubber insulating tape designed for electrical insulation and general protection tasks. It combines flexibility and tear resistance in a thin form factor, offering a reliable wrap for wires, cables and components where a conformable, durable film is required. With a roll length of 32.9 m and a width of 50.8 mm, the tape accommodates a range of repair and maintenance needs while remaining compact for storage and handling.

Advantages

This silicone/rubber electrical tape provides strong adhesion and good conformability to irregular surfaces, enabling effective sealing and protection of splices and joints. Its thin profile maintains flexibility without adding bulk, and the blue color allows for color-coding or visual identification. The material resists moisture and provides electrical insulation suitable for common voltage-rated applications, while the roll size supports multiple uses before replacement.

Подходит для

• Изоляция проводов и кабелей
• Защита и маркировка электромонтажных соединений
• Ремонт и временная фиксация компонентов
• Окружающая среда с повышенной влажностью при выполнении внутренних работ

How to use

Ensure surfaces are clean, dry and free of oils or loose debris before applying the tape. Start the wrap with a short overlap on the base material and stretch the tape moderately while wrapping to conform to shapes and maintain a tight seal. Overlap each turn by approximately half the tape width for consistent coverage and insulation. Trim the tape and press the end firmly to secure adhesion. For multi-layer insulation, apply additional wraps as required by the application or local electrical standards.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight and high temperatures to preserve adhesive properties. For permanent or high-voltage installations consult applicable electrical codes and use tape rated specifically for the required voltage and environmental conditions.
