Premium 3M polyester electrical tape with thermosetting rubber adhesive, 1/2 inch width, 72 yards per roll, 72 rolls per case. Offers 7000V dielectric strength, excellent chemical and moisture resistance, and operates from 32°F to 266°F. UL Listed and RoHS compliant.
3M™ Polyester Film Electrical Tape 57 is a premium general-purpose polyester tape engineered with a thermosetting rubber adhesive for superior electrical insulation applications. This industrial-grade tape features a 1/2 inch width and 72-yard length per roll, with 72 rolls included per case, making it ideal for bulk industrial and occupational use. The tape withstands higher-temperature conditions than tapes with acetate cloth backings, maintaining performance across a temperature range of 32°F to 266°F (0°C to 130°C).
Designed specifically for layer insulation, coil covers, and capacitor wraps where higher electrical strength is required, this tape delivers exceptional dielectric strength of 7000V and insulation resistance of 1 x 10^6 megohms. The polyester film backing provides outstanding resistance against chemicals, solvents, moisture, cut-through, and abrasion, while maintaining excellent conformability and flexibility. With a 2-mil film thickness and 110% elongation at break, this tape ensures reliable performance in demanding industrial environments.
This product is UL Listed and UL Recognized, meeting UL 510 specifications and RoHS 2011/65/EU compliance requirements. The tape features a 5-year shelf life and is specifically formulated for industrial and occupational use only. It is not intended for consumer sale or home use, and must be selected and used in compliance with applicable health and safety regulations and standards such as U.S. OSHA and ANSI guidelines.
