3M 850 Film Tape Black 1-1/2 in 72 yd

This 3M 850 film tape is a black polyester tape with a single-sided acrylic adhesive. It comes in a continuous roll measuring 1-1/2 inches wide and 72 yards long on a 1-1/2 inch core. The tape is designed for electrical and general-purpose applications requiring a durable, high-performance backing. It suits professionals and technicians needing reliable insulation, bundling, or masking solutions.

Thermals noise and power draw

The tape operates reliably across a wide temperature range from -60 degrees F up to 300 degrees F. Its polyester backing and acrylic adhesive maintain bond integrity and physical stability through thermal cycling without softening or becoming brittle. As a passive adhesive product, it generates no noise and draws no power during use or storage. Performance depends on surface preparation and application pressure rather than electrical input.

Upgrades and replacements

This tape replaces cloth, vinyl, or lower-grade polyester tapes when higher tensile strength of 28 lb-in and adhesive strength of 30 oz/in are required. The 1.9 mil thickness provides a conformable yet tough barrier suitable for demanding insulation or wrapping tasks. It is not intended for applications needing conductive properties, extreme abrasion resistance beyond the polyester rating, or widths and lengths other than the specified 1-1/2 inch by 72 yard roll.
