Industrial-grade electrical insulation tape with 600V rating, thermosetting rubber adhesive, and superior heat/oil resistance for motors and transformers
3M™ Composite Film Electrical Tape 44 is a premium industrial-grade electrical insulation tape designed for general-purpose applications in motors, transformers, and electrical equipment. This tape features a unique combination of polyester web and polyester film backing coated with pressure-sensitive thermosetting rubber adhesive, delivering exceptional dielectric strength and electrical properties. The tape is rated for 600V applications and maintains performance across a wide temperature range of 32 to 266°F (0 to 130°C), making it ideal for both hot and cold environments.
The tape offers outstanding resistance to heat, oxidation, solvents, and oils, ensuring long-lasting performance in demanding industrial settings. Its puncture-resistant composition provides excellent mechanical protection for wires, leads, terminal strips, and insulation paper. With a dielectric strength of 5500V and insulation resistance exceeding 1×10^6 megohms, this tape delivers superior electrical safety and reliability. The low halogen formulation and edge tear resistance make it particularly suitable for stick wound coils and transformer applications.
Each case contains 144 rolls of 1/4 inch width and 90 yards length, with a convenient 3-inch paper core for easy dispensing. UL Listed and RoHS 2011/65/EU compliant, this tape meets CSA certification standards and offers a 5-year shelf life. It's specifically formulated for industrial and occupational use, providing economical protection for critical electrical insulation, anchoring, and banding applications.
