PTFE Adhesive Cloth Tape – Insulated High-Temp Sealing Tape
PTFE Adhesive Cloth Tape – Insulated High-Temp Sealing Tape
Meet your go-to solution for heat-resistant, vacuum-stable sealing tasks: the PTFE Adhesive Cloth Sealing Tape. Engineered with a durable PTFE (polytetrafluoroethylene) coating on a woven glass-cloth backing, this tape delivers outstanding performance in demanding environments — from food-sealing machines and packaging equipment to electrical insulation and industrial applications.
Available in multiple width and thickness options (10–50 mm wide; 0.13–0.18 mm thick), you can choose the exact specification that fits your project. The pressure-sensitive silicone adhesive bonds firmly to smooth and semi-rough surfaces while remaining cleanly removable, making it ideal for repetitive industrial processes.
Key Features
- High-Temperature Rated: Maintains integrity at sustained elevated temperatures — perfect for heat-sealing bars, impulse sealers, and oven conveyor belts.
- Vacuum-Stable: Engineered to perform reliably under vacuum conditions, ensuring a consistent seal every time.
- PTFE Cloth Construction: Combines the low-friction, non-stick properties of PTFE with the tensile strength of a woven cloth substrate.
- Electrical Insulation: Provides reliable electrical insulation for wiring harnesses, circuit boards, and component wrapping.
- Chemical Resistance: Resists oils, solvents, and most industrial chemicals.
- Easy Application: Clean, precise adhesive backing allows quick positioning and repositioning before final bonding.
- 3 Color Options: Choose the finish that suits your workspace or application.

Where to Use It
This tape is a versatile staple for workshops, manufacturing floors, and home projects alike. Use it to resurface heat-sealer bars, insulate wiring, line oven slides, or create a non-stick surface on almost any flat tool. Its combination of PTFE's slick surface and cloth-backed durability makes it exceptionally long-lasting even under continuous cycling.

Frequently Asked Questions
Q: What makes PTFE adhesive cloth tape suitable for high-temperature applications?
A: PTFE (polytetrafluoroethylene) has one of the highest continuous-use temperature ratings of any polymer. When bonded to a woven fiberglass cloth backing and paired with a silicone adhesive, this tape can withstand the sustained heat generated by impulse sealers, packaging machines, and industrial ovens — maintaining its bond and insulating properties where ordinary tapes would degrade.
Q: What widths and thicknesses are available for this PTFE sealing tape?
A: The tape is available in widths ranging from 10 mm to 50 mm and in thicknesses of 0.13 mm and 0.18 mm. This range lets you select the precise profile needed for your sealing bar, wiring harness, or conveyor application.
Q: Can this insulated PTFE tape be used for electrical insulation?
A: Yes. The PTFE cloth construction provides excellent dielectric properties, making it well-suited for wrapping wiring harnesses, insulating circuit board components, and bundling cables in both low- and moderate-voltage environments.
Q: Is the adhesive residue-free when removed?
A: The silicone pressure-sensitive adhesive is designed to bond securely during use and release cleanly in most applications, minimizing adhesive residue on equipment surfaces — an important feature for repetitive industrial processes where frequent tape replacement is required.
