Product Description

The 3M 7000048489 is a clear polyester film tape from the Series 396 line, designed for holding, reinforcing, sealing, seaming, and splicing applications across a wide range of trades and industrial uses. The tape measures 1 inch wide and 36 yards long with a total thickness of 4.1 mil. A rubber adhesive backing delivers reliable bonding performance across temperatures ranging from 40 degrees F to 200 degrees F. With a tensile strength of 43 lb/in, this tape holds firmly under mechanical stress, making it well-suited for demanding service environments where tape integrity matters.

Series 396 polyester film tape is commonly used in HVAC, electrical, and general industrial work where a durable, dimensionally stable tape is required. Typical applications include securing insulation, reinforcing seams on flexible duct assemblies, splicing films and foils, and sealing overlaps in sheet materials. Its clear finish makes it unobtrusive in finished installations. Suitable for both shop and field use, this tape is a practical choice for technicians who need a reliable general-purpose film tape in standard roll format.
