3M 00021200035791 850 1in x 72yd Silver Polyester Film Tape

This is a new roll of 3M Scotch 850 Polyester Film Tape, UPC 00021200035791, measuring 1 inch wide by 72 yards long, manufactured in Mexico as confirmed by the label visible in the photos (LOT 107734871). The 850 series features a biaxially oriented polyester (Mylar-type) film backing with a thermosetting rubber-based adhesive, producing a smooth, silver/clear appearance on the film side with a black adhesive face as clearly visible in the photographs. This tape is rated for continuous service up to 150°C (302°F) and offers excellent resistance to moisture, many solvents, and abrasion, making it well suited for electrical insulation, capacitor winding, transformer insulation, coil wrapping, and high-temperature masking applications. The thin, conformable film construction allows it to be used in tight-tolerance electrical and electronic assemblies where dimensional stability and dielectric performance are required.
