Product Description
Our PTFE Glass Cloth Tape (also known as PTFE Coated Glass Fabric Adhesive Tape) is engineered for high-temperature, high-duty industrial applications where release performance, wear resistance, and dimensional stability are critical. It is manufactured from woven fiberglass cloth that is coated and sintered with PTFE, delivering an ultra-low surface energy, non-stick finish along with excellent chemical resistance and mechanical strength. Compared with PTFE film tapes, the glass-cloth reinforcement provides significantly higher tensile strength and better dimensional stability, helping minimize stretching or deformation under tension in continuous production.
One side is coated with a high-temperature silicone pressure-sensitive adhesive for secure bonding to equipment surfaces. The adhesive is designed for reliable hold and typically allows clean removal under recommended conditions; actual removability and any potential residue may vary depending on the substrate, operating temperature, pressure, and dwell time.
Standard thicknesses (total thickness including silicone adhesive): 0.13 mm, 0.18 mm, 0.20 mm, 0.25 mm, and 0.30 mm. Widths up to 1250 mm are available, and other dimensions (width, roll length, and liner options) can be customized upon request. With a PTFE/glass construction service temperature up to 260°C (500°F), this tape is widely used on heat sealing bars and jaws, packaging and food-processing equipment (non-stick release surfaces), and PVC window welding plates—especially in high-cycle operations requiring consistent release and durability.

Q1. What is the difference between PTFE glass cloth tape and PTFE film tape?
A: PTFE glass cloth tape is fiberglass-reinforced, so it offers much higher tensile strength, better dimensional stability (low stretch), and higher wear resistance—ideal for heat sealing, packaging machinery, and PVC window welding. PTFE film tape is more flexible/conformable, better for wrapping uneven surfaces or light-duty release needs.
Q2. Is the thickness measured as total thickness including silicone adhesive?
A: Yes. The listed thicknesses (0.13 / 0.18 / 0.20 / 0.25 / 0.30 mm) are total thickness including the silicone adhesive. Common mil equivalents (rounded): 5 / 7 / 8 / 10 / 12 mil.
Q3. What thickness (5 mil / 7 mil / 10 mil / 12 mil) should I choose for heat sealing?
A:
-
5 mil (0.13mm): best fit on smoother bars, moderate wear
-
7–8 mil (0.18–0.20mm): general-purpose choice
-
10 mil (0.25mm): higher pressure/abrasion, often longer life
-
12 mil (0.30mm): maximum durability for heavy wear (less conformable)
Q4. What is the maximum service temperature? Is 260°C continuous?
A: The PTFE/glass construction is rated up to 260°C (500°F). “Continuous at 260°C” depends on dwell time, pressure/load, substrate, and adhesive performance, so it’s best validated under your actual process conditions.
Q5. Will the silicone adhesive leave residue on metal surfaces?
A: Silicone PSA is designed for strong bonding and often removes cleanly, but residue can vary with surface type/cleanliness, temperature, pressure, and dwell time. A small on-site test is recommended if residue sensitivity is critical.
Q6. When should I replace the tape on a heat sealer or welding plate?
A: Replace when you see surface wear/scratches, edge lifting, tears or glass-fiber exposure, or when film starts sticking despite normal settings. If wear is the main issue, moving up to 10 mil (0.25mm) often helps.
Q7. Do you offer black antistatic PTFE glass cloth tape for ESD applications?
A: Black antistatic versions are commonly used for ESD-sensitive electronics processing. Requirements vary by grade, so confirm your target ESD needs (e.g., resistivity range and operating temperature) to match the appropriate specification.
