3M 7000048643 Ptfe Film Tape 5498 1 Inch X 36 Yd

Product Description

The 3M 7000048643 is a beige PTFE film tape (product line 5498) constructed from extruded polytetrafluoroethylene film at 4.0 mil total thickness. It uses a non-silicone rubber adhesive, making it the correct choice for applications where silicone contamination is a concern. Once applied, the PTFE surface is exceptionally slick and chemically resistant, supporting sealing and masking operations in demanding environments. The tape resists curling during unwind, which speeds up application and reduces waste during installation. Licensed trades workers and technicians in HVAC, plumbing, electrical, and general industrial settings commonly reach for this product when silicone-free performance is required.

This tape is suited for sealing, masking, and surface-protection tasks in both residential and commercial settings. It performs in chemically aggressive environments where standard film tapes would degrade. The non-silicone adhesive system makes it appropriate for paint booths, electronics manufacturing, and any process line where silicone residue would cause defects or adhesion failures. Technicians also use it for low-friction liner and slide surfaces where the slick PTFE face reduces drag or sticking between mating components.

Key Features

• 4.0 mil total thickness extruded PTFE film construction
• Non-silicone rubber adhesive eliminates silicone contamination risk
• Chemically resistant surface supports sealing and masking applications
• Slick PTFE face reduces friction when used as a liner or slide surface
• Resists curling during unwind for faster, cleaner application
• Single-roll format: 1 inch wide by 36 yards

Compatibility

Designed as a general-purpose PTFE film tape for sealing, masking, and low-friction surface applications in environments requiring a non-silicone adhesive system.

Installation Notes

Surface preparation is critical before applying any pressure-sensitive tape; clean and dry the substrate thoroughly to ensure proper adhesion. In HVAC and plumbing contexts, de-energize or shut off the system before taping any sealing or masking surfaces. Unroll and apply with steady, even hand pressure to eliminate air pockets. Follow applicable local codes and manufacturer guidelines for the specific system being serviced.
