High temperature tapes are heat resistant, which means they're perfect for sealing vinyl and glass, or preventing glass from shattering if it falls. They come in a wide range of colors, including red, yellow, blue, green, purple, white, black, brown, orange, pink, and more.

High temperature tapes are durable and long-lasting, making them ideal for DIY projects, such as sealing glass. They're also great for sealing vinyl, such as sealing windows or sealing a car's windshield.

Our lab evaluates high temperature tapes for performance, including durability, and ease of use. We test the adhesive strength, which refers to the strength of bonding between the tape and the surface on which it's applied. We also test the burn time, which is how long it takes for the tape to reach 500 degrees Fahrenheit. Our top picks are:

APT, 1 mil Thick Polyimide Adhesive Tape, HighTemperature and Heat Tape, for Masking, Soldering, Electrical, 3D Printer Application. (2

APT Advanced Polymer Tape APT

by Advanced Polymer Tape Inc.

No Shrinking, Curling, Or Lifter Edges- Made with high temperature silicone adhesive and premium film. Our tape resists curling, shrinking, and lifted edges every time.

The APT Polyimide tape had excellent toughness and insulation, which was impressive considering how thin it was. Its low tackiness was excellent, and our sample successfully bonded to a variety of surfaces. Because APT tape is extruded, it retains its shape, so you can roll it tightly without crushing it. Our sample also bonded to a variety of materials, including metal, glass, and ceramic, and it maintained its tough, flexible properties through repeated heating. The tape is also very flexible, so it's easy to apply. The adhesive was strong enough that it held our sample together when subjected to rigorous force. The APT tape also didn't leave any residue, and there were no visible air bubbles when we applied it into crevices.

High Temp Tape, ELEGOO 4 Pack Polyimide High Temperature Resistant Tape Multi-Sized Value Bundle 1/8’’, 1/4’’, 1/2’’, 1’’ with Silicone Adhesive for Masking, Soldering etc.

ELEGOO High Temp Tape


With silicone adhesive for easy release and leaves no residue after peel away

The 4 pack of Elegoo high temperature tape is a great value, offering 4 of the largest sizes that we tested for soldering and electrical insulation. The tape is thick and rigid, and it resists heat well, although not quite as well or as reliably as the T3 tape we used with our previous top pick. The Elegoo tape's adhesive is thick and strong, but it's not as reliable as the T3 adhesive. The Elegoo tape's electrical insulation was excellent, and it's a reliable choice for splicing wires and masking circuit boards. The small sizes are a good value, and all three of the larger sizes are a good value. The smaller sizes are better suited for short term use, and the large ones should last you a long time. The Elegoo tape is about half the cost and a quarter of the weight as our former top pick, the T3 tape.

Bertech High Temperature Tape, 1 Mil Thick, 1 Inch Wide x 36 Yards Long, Polyimide Film with Silicone Adhesive, 500°F Resistance, High Temp Resistant Polyimide Tape for Masking, Soldering and PCB

Bertech High Temperature Tape

by Bertech

DURABLE MATERIAL: RoHS- and REACH-compliant tape is made using a soft coating of polyimide film with a silicone adhesive that leaves no residue

Bertech's high-temperature polyimide tape is ideal for a range of applications, including high-temperature sealing and insulation, high-temperature solder mask, PCB applications, and high-temperature masking. It's thick enough to resist penetration by molten solder and withstand temperatures of 500°F (260°C), and it's tough enough to keep its shape even when stuck to irregular surfaces. It's easy to work with, too: thanks to its flexible adhesive, the Bertech high-temperature polyimide tape is easy to work with, and it's flexible enough to conform to irregular surfaces. However, it's somewhat brittle, so it's best used on flat, clean surfaces, and it's prone to tearing, so use it with care.

6 Rolls High Temperature Tape Heat Vinyl Press Tape Heat Resistant Sublimation Tape 3D Printing Heat Tape for Heat Transfer Electronics Masking (10 mm)

Outus 6 Rolls High Temperature Tape Heat Vinyl Press Tape Heat Resistant Tape Sublimation 3D Printing Heat Tape for Heat Transfer Electronics Masking (10 mm)

by Outus

Reliable material: the heat press tape is made of polyimide film and silicone adhesive, with smooth surface and high insulation, the strong organic silicone adhesive is easy to adhere, and there is no residue after peeling

This heat-resistant tape, once pressed, will remain pressed. However, its water resistance rating is limited to 280C. That's also why it's best used for heat-resistant applications, such as hot pressing and soldering. The tape's coloring is blue, which makes it easier to identify in complex situations. The tape's width is 0.9 mm, which gives you more options. The adhesive is on the reverse side of the tape, so it's easy to apply. The tape is thick enough to remain flat when pressed, but thin enough not to affect the heat transfer. The tape's adhesive is strong enough to withstand 280C, but it's not necessarily strong enough to withstand the heat from soldering irons or hot presses. The tape's adhesive is strong enough to resist peeling. However, it is not strong enough to resist water. The tape withstands 280C, so it's suitable for heat-resistant applications. The tape is too thin to resist water.

Newtex High Heat Resistant Tape - Extreme Temperature Aluminum Foil Z-Flex Tape - Pressure Sensitive Adhesive Ducting, Insulation, Reflective Heat Barrier Tape Roll (2

Newtex High Heat Resistant Tape

by Newtex

SILVER ALUMINUM FOIL TAPE: This heat reflective tape is designed to act as a heavy duty heat barrier for fixed surfaces. Just make sure the surface is clean and free of debris before applying. Take the backing of the tape, press on to the surface and you're ready to go. You will need additional manual bonds for surfaces subject to stretching, twisting, or vibration.

This tape is thin and sticky, so it sticks well and stays in place. It's durable, too, and won't tear easily. The backing is pressure sensitive, so it's easy to apply and remove, and the tape itself is thin enough to slide over things easily. It resists heat well, up to 300 degrees Fahrenheit, so it's useful for shielding cables from heat-radiating equipment. The reflective side has a shiny, metallic-silver look, so it's useful for hiding equipment and wires. The tape is thick enough to use on roofs, but it's also thin enough to use on inner walls and behind cabinets. The adhesive burns off over time with consistent heat exposure, so we recommend manually bonding with hose clamps or stainless steel zip ties for long term use.
