When you are looking for a specific kind of electrical or thermal insulating tape, we have a variety in stock to handle both voltage and high temperature applications. Our High Temperature Silica Tape has a continuous temperature rating of 1,800°F and maximum short-term temperature of 3,000°F. This high temperature silicone silica tape is designed using 96% pure SiO2 silica fiber.

Installation Tip: To secure TPC Thermo-Trex® High Temperature Silica Tape in an intended application, each end can be terminated using a stainless steel wire tie or hose clamp. This prevents unraveling and any movement after the adhesive backing has burnt off.

If you need a non-adhesive, self vulcanizing insulating tape, our Vulko-Wrap™ Electrical Insulating Tape is perfect for resisting oil, water, ozone and many chemicals. By only adhering to itself it makes installation and removal on bus bars, terminations and electrical splices quick and easy. Vulko-Wrap Insulating Tape is available in black or yellow in two sizes.  We also offer a reinforced style for applications where additional mechanical strength is needed.

Choosing the Right Tape to Protect Cable or Wire


TPC’s range of Vulko-Wrap™ and Thermo-Trex® tapes can be used for most maintenance related tasks. Designed to work well with high-voltage and high-temperature applications, these products offer ease of installation, extreme temperature properties, self-sealing design and the versatility, strength and length for most applications.

Let's take a closer look at TPC's tape options:

  • Vulko-Wrap™ Insulating Tape (Black, Blue and Yellow) - TPC’s popular self-vulcanizing insulated wrap. Made of a specially compounded, synthetic silicone elastomer, this tape is resistant to oil, water, ozone and many chemicals. It has a high dielectric strength and can be used on all electrical connections. Plus, removing it leaves no residue. Vulko-Wrap stretches more than 2-1/2 times its length allowing it to tightly grip any surface. Click here for video demo.
  • Vulko-Wrap™ Insulating Tape (Black Reinforced) - Vulko-Wrap’s reinforced option can also be used for any electrical connection. Made of a specially compounded, synthetic silicone elastomer with embedded reinforcing fibers; resistant to oil, water, ozone and many chemicals. It is available in 40 mil thickness.

  • Thermo-Trex® High Temperature Silica Tape - This electrical tape is a good choice for work with hoses, assemblies, and cable wires that are exposed to temperatures ranging from 1,800°F-3,000°F. Made with pure SiO2 silica fiber outer layers, this thermostatically controlled tape is not affected by extreme heat and will not unravel. No need to disconnect hoses or cables when fitting this strong and cut-resistant tape. When heated, the backing decomposes, leaving the assembly, cable wire or hose wrapped flawlessly. Thermo-Trex® Silica tape is not an insulating tape.
