Best High Temperature Tape of 2025

"I used this tape to seal a pellet stove exhaust pipe connection. It provided a solid smoke seal without needing to replace metal parts. I applied it over the metal joints, and it worked perfectly."

"Unfortunately, I found the adhesive on this tape to be extremely weak. It wouldn’t stick to the material I needed it for, so I had to return it for a refund."

"I bought this tape to secure black shades on my window during summer. Despite the heat, it has held up wonderfully for a month without any issues, unlike the original adhesives on the shades."

"This tape works great with heat and my Cricut press."

"I needed this tape to prevent heat creep on my 3D printer. Now, I don't replace thermistors regularly. There's a lot of tape in the order. I could have chosen wider tape, but this works fine for me."

"After using this tape for several months, I can say it has no issues unlike the standard copper tape. I appreciate the narrow version since I rarely need wider pieces. It didn't fit my dispenser perfectly, but a little foam tape fixed that easily. I definitely suggest it for sublimation projects—it's much cheaper than Cricut's option."

"I initially bought this tape to complete a bill with my first fpgbc kit, and I have to say, it was perfectly done. The tacton tape worked excellent and was super easy to use. It's very effective and a great value for your money. Thankfully, the rolls come in varying sizes, which helped me distinguish the right one for my project."

"I found this tape to be a nice little set of Polymide tapes. I feel like I reach for this stuff constantly lately; it's just so useful. I really appreciate the variety of sizes since I hate wasting it—it's not cheap. The quality is nice, and I have no complaints."

"This tape worked like a charm for cord management inside my Bambu Lab P1S. I wasn't keen on using regular tape or anything less temperature-safe. I wanted something that wouldn't peel or melt and was very pleased with this product. It's affordable and looks like it belongs in an emergency kit for a space shuttle!"

"I recently used the Bertech High Temperature Tape for a project that needed a reliable adhesive for high temperatures. It exceeded my expectations! The 1-inch width provided great coverage, and the 36 yards length meant I had plenty of tape. The 1 mil thickness was perfect—strong yet flexible. It adhered well, and the polyimide film with silicone adhesive showed no signs of melting. It unrolled smoothly, stuck firmly, and left no residue, keeping my workspace clean. This tape is now a staple in my toolbox for electronics projects. I would give it 5 stars for performance!"

"I bought this tape after seeing a YouTube recommendation, and I'm really happy with my choice. I used it on my knives before sharpening them, and there were no scratches!"

"I purchased this tape for a college research project involving perovskite solar cells. Students use it in the chemistry department, securing ITO glass to the hot plate while heating the solar cell materials. After analyzing the substrates with an X-ray gun, we found elements like titanium and lead. It's been perfect for our needs!"

"I believe this tape is the best fN tape ever. It never leaves any residue, and its heat resistance is unmatched."

"When I create sublimated jewelry on acrylic, using the extra wide tape allows me to cover the entire charm, avoiding tape edge impressions. I’m so pleased that wide tape is available! This tape worked wonderfully, and I plan to buy more from this brand."

"I was hopeful that this tape would work outdoors, but unfortunately, it did not adhere to a plastic panel at the front end."

"The tape is so thin that it's almost impossible to remove from the roll. I found it hard to believe it could withstand 500 degrees as advertised, and it didn't meet my expectations. I probably won't purchase it again."

"I've only used it a few times, and it works exactly as advertised. No residue at all."

"I bought this for my 3-D printing bed. Good adhesive quality, though I wish the rolls weren't so small. Fitting them back in the bag is a bit tricky."

"The tape is fantastic. Very strong and has quickly become my favorite. The only drawback is that the rolls are small, making it difficult to use with a standard tape dispenser, which slows me down."

"Let's be real – no one gets giddy about aluminum foil tape. But I have to say, 3M Aluminum Foil Tape 3381 is impressive! It’s like having a superhero for leaky ducts, sealing those gaps and saving on energy bills. Who knew tape could impact finances like that? Plus, it’s a DIY MacGyver for fixing rattles and holes. And honestly, it holds up in any weather, truly a cold weather warrior. I even found it helps with squeaky cabinets! And hey, in case of a zombie apocalypse, this tape could really come in handy!"

"I used this tape along with insulation wrap on my portable air conditioner. Before, the heat from the hose made it useless, but now, thanks to this tape, my air conditioner actually cools the space! It holds everything in place nicely, though I didn’t rate 'easy to remove' since it’s meant to stick well."

"I bought this tape to cover holes in my HVAC unit and secure ducting to vents. It has worked great even in rainy conditions. The quality is obvious with its thickness and adhesion. I have no complaints and would definitely recommend this product to others."

"I absolutely love the high-quality materials used in this product!"

"The customer service was incredibly helpful when I had questions."

"I've been using it for months, and it's still durable and looks great."

"I used this product to insulate my car's wiring harness. After two years of use, I had to create a new harness for a transmission upgrade, and the insulation still had a strong grip on the old one, requiring me to cut it off. It performed well under over 200 degrees Fahrenheit and proved to be very durable."

"For my 2014 Corvette, I chose this tape to protect the LED tailpipe light wiring. It needed to be routed around hot exhaust, and this tape resembled what GM used for other wiring in that area. I had no problems at all with it."

"I found this tape to be excellent for my woodstove! It outperformed tin foil tape and is rated for much higher heat than anything I could find on Amazon. Initially, there was a slight smell during the first few burns, but after that, it was smoke leak-free! I recommend buying two rolls to ensure you have enough."
