Premium polyester film electrical tape with thermosetting rubber adhesive, rated 7000V dielectric strength, ideal for industrial insulation applications with superior chemical and moisture resistance.
3M™ Polyester Film Electrical Tape 57 is a premium general-purpose electrical insulation tape designed for industrial and occupational applications requiring excellent dielectric strength and superior performance. This high-quality tape features a polyester film backing with thermosetting rubber adhesive, making it ideal for layer insulation, coil covers, and capacitor wraps in demanding electrical environments. The tape withstands a wide temperature range from 32°F to 266°F (0°C to 130°C), providing reliable performance in both hot and cold conditions.
Engineered with a 2-mil film thickness and 3.5-mil total tape thickness, this electrical tape delivers exceptional conformability and exhibits outstanding chemical, solvent, and moisture resistance. The robust polyester backing resists cut-through and abrasion, ensuring long-lasting protection in harsh industrial settings. With a dielectric strength rating of 7000V and insulation resistance of 1 x 10^6 megohms, this tape meets UL 510 standards and is UL Listed and Recognized, making it compliant with RoHS 2011/65/EU regulations.
Each case contains 48 rolls of 72-yard length tape in 0.75-inch width, providing ample supply for large-scale industrial projects. The tape maintains a 5-year shelf life, ensuring consistent quality and performance throughout storage. Ideal for electrical contractors, maintenance professionals, and industrial facilities requiring premium electrical insulation solutions that exceed industry standards.
