PTFE film adhesive tape (also known as Teflon film tape) is a functional tape made of polytetrafluoroethylene (PTFE, commonly known as Teflon) film as the base material and coated with high-temperature resistant pressure-sensitive adhesive (silicone adhesive, acrylic adhesive) on the surface.

Its structure usually includes:

1. PTFE film layer: provides core performance (heat resistance, non-stick, insulation, etc.).

2. Adhesive layer: ensures that the tape can be firmly attached to various surfaces.

3. Release protective layer (such as release paper/film): peel off before use.

Features of PTFE film adhesive tape:

1. Excellent temperature resistance

- Working temperature range: -70°C to +260°C (can withstand 300°C for a short time), adaptable to extreme high and low temperature environments.

2. Excellent non-stickiness

- The surface energy is extremely low, almost no adhesion to any substance (such as glue, resin, food residue), easy to clean.

3. Strong chemical stability

- Resistant to strong acids, strong alkalis (including concentrated sulfuric acid, aqua regia), organic solvents and corrosive gases, suitable for chemical environments.

4. Outstanding insulation performance

- High dielectric strength, arc resistance, widely used in wire wrapping, electronic component insulation protection.

5. Low friction coefficient

- The friction coefficient is only 0.05~0.1, which reduces mechanical wear and is suitable for guide rails, bearings and other parts that need lubrication.

6. Flexible and easy to fit

- PTFE film is soft and can fit tightly to irregular surfaces (such as pipe threads and complex molds).

7. Weather resistance and durability

- Anti-ultraviolet and aging resistance, stable performance for long-term outdoor use, and lifespan far exceeds that of ordinary tapes.

8. Various colors

- Common white, gray, black, red, etc.

9. Safety certification

- Some products have passed FDA (food grade) or RoHS certification and can be used in sensitive fields such as food processing and medical equipment.

Typical application scenarios:

- Industrial field: anti-sticking of high-temperature production lines, sealing of corrosive pipes.

- Electrical and electronic: circuit board welding protection, insulation of high-voltage equipment.

- Food processing: anti-sticking of baking molds, heat-sealed parts of packaging machinery.

- Automobile manufacturing: engine wiring harness insulation, anti-corrosion of brake systems.
