3M 7000049050 Ptfe Film Tape Gray 50mm X 33m

Product Description

The 3M 7000049050 is a PTFE extruded film tape with a silicone adhesive backing, designed for industrial sealing, masking, and low-friction surface applications. This is the thicker version of 3M Tape 5490, offering a more robust PTFE film that delivers an exceptionally slick surface upon application. The silicone adhesive resists curling during unwind, making it easier to handle and apply cleanly. The PTFE film surface provides strong chemical resistance, making this tape suitable for environments where exposure to solvents, acids, or aggressive process chemicals is a concern. It is commonly installed by industrial maintenance technicians, pipefitters, and HVAC service professionals.

This tape is used in a wide range of industrial and trade applications including sealing, masking, and protecting surfaces that require low friction or chemical resistance. Typical installation scenarios include wrapping guide rails, slide surfaces, chute linings, and sealing applications where a non-stick, chemically resistant barrier is needed. The roll format — 50mm wide by 33 meters long — suits both production-line use and field service repairs. Its resistance to curling during unwind improves efficiency in repetitive wrap or masking tasks.

Key Features

• PTFE extruded film construction delivers a slick, low-friction surface upon application
• Thicker film profile compared to 3M Tape 5490 for added durability and wear resistance
• Silicone adhesive backing resists curling during unwind for cleaner, faster application
• Chemical resistant surface suitable for sealing and masking in harsh environments
• Gray color for visual identification in multi-tape or multi-layer applications
• Roll format minimizes waste and suits both shop and field use

Compatibility

Designed as a general-purpose PTFE film tape for sealing, masking, and low-friction surface applications across industrial, HVAC, and mechanical trade settings where chemical resistance and a non-stick surface are required.

Installation Notes

This tape is typically applied by hand or with a tape dispenser; no special tooling is required. Ensure the application surface is clean, dry, and free of oils or debris before applying to achieve proper adhesion. When used in sealing or masking applications, overlap edges as appropriate for the process requirement. Avoid stretching the tape beyond its natural lay to prevent gaps or lifting at the edges.
