Professional-grade polyester film electrical tape with thermosetting rubber adhesive, offering superior chemical and moisture resistance, 3500V dielectric strength, and temperature range of 0-130°C. Case of 36 rolls, 1 inch x 72 yards each.
3M™ Polyester Film Electrical Tape 74 is a professional-grade, general-purpose electrical tape designed for industrial and occupational applications. This 0.02mm (0.8 mil) thick tape features a thermosetting rubber adhesive with polyester film backing, offering exceptional resistance to chemicals, solvents, moisture, abrasion, and cut-through. The tape provides excellent electrical strength and dielectric properties, making it ideal for coil applications where space is at a premium.
With a temperature operating range of 0°C to 130°C (32°F to 266°F), this tape maintains its performance in demanding environments. The polyester backing ensures durability and conformability, allowing the tape to wrap tightly around irregular surfaces. Each roll measures 1 inch wide by 72 yards long, and this case contains 36 rolls for bulk purchasing convenience. The tape meets UL 510 standards and is RoHS 2011/65/EU compliant, ensuring it meets strict regulatory requirements for industrial use.
The tape delivers a dielectric strength of 3500V and provides 100% elongation at break, demonstrating superior flexibility and electrical insulation capabilities. With an insulation resistance of 1 x 10^6 megohms and a 5-year shelf life, this product offers reliable long-term performance for electrical maintenance, repair, and installation tasks in industrial settings.
