Benefits
Low-Friction Surface
The PTFE surface provides an extremely low-friction interface, helping materials slide more easily across machinery surfaces.
Non-Stick Performance
The PTFE construction creates a non-stick surface that can help minimize material buildup and sticking on processing equipment.
High-Temperature Resistance
3M™ PTFE Glass Cloth Tape 5451 can perform across a wide temperature range, with a stated long-term use range from -73°C to 260°C.
High Mechanical Strength
Unlike conventional PTFE film tapes, the woven glass cloth reinforcement provides additional tensile strength and resistance to tearing and puncturing.
Chemical Resistance
PTFE provides excellent resistance to many chemicals, making the tape suitable for challenging industrial environments.
Long-Term Durability
The combination of PTFE, woven glass cloth, and silicone adhesive provides a durable solution for applications involving heat, friction, pressure, and repeated processing.

Applications
3M™ PTFE Glass Cloth Tape 5451 is particularly suitable for applications where high temperature + low friction + non-stick performance + mechanical strength are required.
1. Heat Sealing Machines
The PTFE surface helps prevent heat-sealed materials from sticking to equipment surfaces.
2. Packaging Equipment
It can be used on packaging and heat-sealing machinery to reduce material buildup and improve release performance.
3. Ironing and Pressing Equipment
The low-friction PTFE surface can provide a durable release surface for high-temperature pressing operations.
4. High-Temperature Bundling
The reinforced construction makes the tape suitable for selected high-temperature bundling applications.
5. Composite Manufacturing
3M recommends 5451 for mold release in composite bonding, where its non-stick surface can help provide separation between materials and processing surfaces.
6. Separation of Dissimilar Materials
The tape can act as a barrier between surfaces that need to remain separated during processing.
7. Heat Shrink Wrapping
The combination of temperature resistance and low friction makes it suitable for selected heat-shrink wrapping operations.

Why Choose 3M™ PTFE Glass Cloth Tape 5451?
3M™ PTFE Glass Cloth Tape 5451 is particularly valuable when a standard PTFE film tape does not provide sufficient mechanical durability.
Its key advantage is the combination of:
PTFE low friction + glass cloth reinforcement + silicone adhesive + high-temperature performance
This construction provides:
- Better resistance to tears and punctures
- High tensile strength
- Excellent release properties
- Low friction
- Chemical resistance
- High-temperature capability
- Durable industrial performance
For applications involving repeated contact, friction, heat, or mechanical stress, the reinforced glass cloth construction can provide a more robust solution than conventional PTFE film tape.
Installation Guide
Step 1: Clean the Surface
Remove dust, oil, grease, moisture, and other contaminants from the application surface.
Step 2: Cut to Length
Cut the required length of 3M™ PTFE Glass Cloth Tape 5451 using a suitable cutting tool.
Step 3: Position the Tape
Align the tape carefully with the target surface. Avoid excessive stretching during application.
Step 4: Apply Pressure
Apply firm, even pressure across the tape to establish good adhesive contact.
Step 5: Check the Edges
Make sure the tape is firmly attached and that there are no lifted edges, wrinkles, or trapped air.
Step 6: Test Under Operating Conditions
For new applications, validate adhesion, temperature resistance, release performance, and durability under actual process conditions.
Storage
For best performance:
- Keep the tape in its original packaging.
- Store in a clean and dry environment.
- Protect from direct sunlight.
- Avoid excessive heat and humidity.
- Keep away from chemicals and contaminants.

FAQ
What is 3M™ PTFE Glass Cloth Tape 5451?
It is a premium PTFE tape reinforced with woven glass cloth and coated with a pressure-sensitive silicone adhesive. It provides a low-friction, non-stick surface combined with high mechanical strength and temperature resistance.
What is 3M™ 5451 used for?
Typical applications include heat sealing machines, packaging equipment, ironing and pressing equipment, high-temperature bundling, composite mold release, and separation of dissimilar materials.
How high a temperature can 3M™ PTFE Glass Cloth Tape 5451 withstand?
3M specifies a long-term temperature-use range of approximately -73°C to 260°C (-100°F to 500°F).
Is 3M™ 5451 chemical resistant?
Yes. The PTFE construction provides excellent chemical resistance and is suitable for many challenging industrial environments.
Is 3M™ 5451 a non-stick tape?
Yes. The PTFE surface provides very low friction and non-stick/release characteristics, making it useful on heat-sealing and packaging equipment.
What is the difference between 3M™ 5451 and 3M™ 5453?
Both are PTFE glass cloth tapes, but they have different constructions and performance characteristics. 5451 has a typical total thickness of 0.14 mm, while the older 3M technical documentation lists 5453 at approximately 0.21 mm, with higher adhesion and tensile strength.
Can 3M™ 5451 be die-cut?
Yes. PTFE glass cloth tape can be converted into custom shapes for suitable industrial applications. The appropriate tooling and process should be evaluated according to the required geometry and production volume.
