3M™ 5 Polyester Film Electrical Tape is a 1-mil conformable polyester film tape with acrylic adhesive for excellent solvent resistance. It is specified for insulating applications requiring a thin, durable tape with high dielectric strength, such as for use in coil and capacitor and holding applications. Rated for use up to 130 degrees C (266 degrees F), it withstands higher temperature conditions than tapes with acetate film backing.
