Glass Cloth Tapes (PTFE & Silicone Adhesive)

Specifically designed for use in high-temperature applications, glass cloth tape is coated with a specialized adhesive that provides high heat resistance. This type of tape includes both PTFE impregnated fiberglass cloth as well as electrical-grade glass cloth tape. High-temperature silicone adhesive is what gives this type of tape its high level of heat resistance. offers glass cloth tapes in a broad array of styles, including aluminum foil glass cloth tape, PTFE glass cloth type and more. The most common applications for this kind of tape include use in electrical apparatuses and to protect and shield various components such as control cables and harnesses.

Product Applications:
  • Protecting and shielding components in electrical apparatuses
  • Use as an insulator and protective barrier in electrical equipment
  • Thermal and plasma spray marking
  • Moderate grit-blasting
  • Securing thermal insulation
Glass cloth tape is popular because it is highly conformable, with highly flexible accommodation around turns and angles, and is coated with a temperature-resistant adhesive system. The silicone adhesive system of glass cloth tape allows it to perform well in temperatures up to 500 degrees Fahrenheit. Additionally, this type of tape is highly abrasion resistant and offers a high tensile strength, so it's perfect for use in industries ranging from aerospace to electrical to construction.

You will want to choose your high-temperature glass cloth tape depending on the applications for which you intend to use it. For example, PTFE fiberglass cloth tape can be used as a primary insulation in electrical equipment, while electrical-grade fiberglass cloth tape is well-suited for thermal and plasma spray marking applications. We also carry aluminum foil glass cloth tape, which is regularly used for moderate grit-blasting and securing thermal insulation. We stock a wide variety of JVCC glass cloth tape in 5- to 12.1-mil thickness options at
