3M 7000123940 Ptfe Glass Cloth Tape 5151 0.75in X 36yd 3.5 Mil

Product Description

The 3M 7000123940 is a general purpose PTFE glass cloth tape sold under the 3M 5151 product line. It consists of a fiberglass cloth substrate impregnated with PTFE (Polytetrafluoroethylene) and coated with a silicone pressure-sensitive adhesive. The tape measures 0.75 inches wide by 36 yards long at 3.5 mil thickness and has a light brown finish. PTFE impregnation gives the tape chemical resistance, a low-friction surface, and strong abrasion and puncture resistance with minimal moisture absorption. Technicians and equipment maintenance crews use it on heat sealing machines and process equipment where consistent, easy-release performance is required over extended service cycles.

This tape is suited for industrial and commercial process environments. Common applications include lining conveying chutes, troughs, and ducts to keep material flow moving without buildup or sticking. It also sees heavy use on heat sealing bars and platens in packaging equipment, where repeated heat and pressure cycles demand a durable, non-stick surface. The silicone adhesive holds reliably against heat and chemicals while still allowing clean removal when service is needed.

Key Features

• PTFE-impregnated glass cloth provides a low-friction, non-stick surface for easy material release
• Resistant to most chemicals, making it suitable for harsh process environments
• High tensile strength and puncture resistance from the woven fiberglass substrate
• Low moisture absorption extends service life in humid or wet process areas
• Silicone pressure-sensitive adhesive delivers long-lasting hold with clean removability
• 3.5 mil total thickness balances conformability with durability on flat process surfaces

Compatibility

Designed for use on heat sealing machines, process equipment, and conveying components including chutes, troughs, and ducts where a non-stick, chemically resistant surface is required.

Installation Notes

This tape is applied by hand or with a tape dispenser and does not require special tooling. Before application, clean the substrate surface thoroughly to remove oils, dust, and debris to ensure full adhesive contact. On heat sealing equipment, power down and allow surfaces to cool to a safe handling temperature before applying or replacing tape. Avoid stretching the tape during application, as distortion can reduce adhesive contact area and shorten service life.
