3M 7000029150 Ptfe Film Tape 5491 Gray 3in X 36yd

Product Description

The 3M 7000029150 is a PTFE extruded film tape with a silicone adhesive backing, sold as a single roll measuring 3 inches wide by 36 yards long at 6.5 mil total thickness. The extruded PTFE film construction delivers an exceptionally slick, low-friction surface on application and resists curling during unwind — a practical advantage when taping in tight or overhead locations. The silicone adhesive provides reliable hold across a wide temperature range and bonds well to irregular surfaces. This tape is used in industrial, HVAC, plumbing, and process-equipment applications where chemical resistance, release properties, or high-temperature performance are required. Installation is handled by mechanical trades, maintenance technicians, and industrial service professionals.

This tape is suited for sealing, masking, and surface-protection tasks in environments where chemical exposure or elevated temperatures would degrade standard film tapes. Common applications include wrapping sliding surfaces and guides, protecting components during soldering or powder coating, lining chutes and hoppers for improved material flow, and masking surfaces during chemical processing. The 3-inch width and 36-yard roll length make it practical for both spot work and longer continuous runs without mid-job splicing.

Key Features

• PTFE extruded film construction provides a low-friction, non-stick surface
• Silicone adhesive resists high temperatures and bonds across a range of substrates
• 6.5 mil total thickness — heavier-duty than the 5490 series for added durability
• Resists curling during unwind for cleaner, faster application
• Chemical-resistant surface suitable for sealing and masking in process environments

Compatibility

Designed as a general-purpose PTFE film tape for industrial, HVAC, plumbing, and mechanical applications requiring chemical resistance and low-friction surface properties.

Installation Notes

Clean and dry the target surface before application to ensure full adhesive contact. Apply firm, even pressure along the tape length using a roller or squeegee tool to eliminate air pockets. No mechanical fasteners or special tools are required, but silicone-adhesive tapes should not be repositioned repeatedly once set. Follow applicable facility or job-site safety protocols when working near chemical or high-temperature environments.
