Professional-grade polyester electrical tape with thermosetting rubber adhesive, rated for 7000V dielectric strength, temperature range 32-266°F, ideal for industrial insulation applications.
3M™ Polyester Film Electrical Tape 57 is a premium general-purpose polyester tape featuring a thermosetting rubber adhesive, specifically designed for electrical insulation applications requiring exceptional dielectric strength. This professional-grade tape is engineered to withstand demanding industrial conditions with a temperature range of 32°F to 266°F (0°C to 130°C), making it ideal for layer insulation, coil covers, and capacitor wraps in electrical systems.
The tape features a 2-mil film thickness with a polyester film backing that provides superior resistance against chemicals, solvents, moisture, cut-through, and abrasion. With a dielectric strength rating of 7000V and insulation resistance of 1 x 10^6 megohms, this tape delivers reliable electrical performance for critical industrial applications. The conformable nature of the tape allows it to adapt easily to irregular surfaces while maintaining excellent adhesion and integrity.
Each case contains 144 rolls of tape, with each roll measuring 72 yards in length and 1/4 inch in width. The product is UL Listed and RoHS 2011/65/EU compliant, ensuring compliance with international safety and environmental standards. With a 5-year shelf life, this tape is designed for industrial and occupational use only, meeting the stringent requirements of trained professionals in electrical, manufacturing, and maintenance applications.
