## Features

- INTRODUCTION: LLPT matt aluminum foil tape is constructed with 3 layers. The top is nano carbon material which is uniformly painted on aluminum foil and will not get rid of the black layer in cold or hot, weatherproof, long lasting painting to anti scratch-off, converts heat energy into infrared-radio frequency by high thermal radiation efficiency of carbon atom to transfer heat dissipation efficiency; the middle layer is aluminum foil and the 3rd layer is pressure sensitive acrylic adhesive.
- PRODUCT FEATURE: High thermal conductivity(w/m-k 400-2500), thermal radiation (1000-6000) and flexibility; Supreme performance on resistance of flame, vapor, moisture, ultraviolet (UV), weather, cold, heat, oil, smoke and etc with acrylic coated adhesive. LLPT Nano Carbon Aluminum Foil stays high stability and strength for long life support, great efficiency on cooling and heating with operational temperature from -30°C to 260°C. Works 10 times better than traditional graphite sheet.
- APPLICATION: Industrial grade, efficient thermal conduction for HVAC systems, AC units, heaters, vents, metal finishing, electronics, automotive, aerospace, recreational vehicle, construction, industrial/home air duct, kitchen masking to avoid oil in gap, sealing, seaming, heat shielding, harness wrapping, joining, vibration damping, electroplating, plastic protection, milling, paint stripping and so on.
- INSTALLATION: Simply wrap or cut the size you need, peel off the backing and stick the tape to the object with hard press. The coated acrylic adhesive is extremely strong but is still easy to remove without any residue, cut, tear and peel. Pressure sensitive black foil tape enables to be fit on corrugated or irregular corners and joints. Very high bonding for plastic, ceramic, concrete, copper/brass and other metals.
- LLPT-TAPES: LLPT produces various tapes for industrial & commercial use with ideal sizes & thickness based on the desires of users. LLPT is dedicated to provide high utility on the product with competitive price with great packing protection during transition. Search LLPT-TAPES on desertcart for other tapes like EVA Insulation Tape, PET Repair Tape, Woodworking Tape, Thermal Conductive Tape, PE Foam Tape, Black/Gray/Clear Acrylic Tape, Duct Tape, Silicon Tape, Gaffer Tape and so on.

## Questions & Answers

**Q: Can I use this at the very end of a car exhaut that only get's at most, 150 F ?**
A: I don't see any reason you could not use it in that low of heat, I wrapped all my pellet stove joints with this and it is holding well

**Q: Is this rated nontoxic?**
A: Nontoxic.

**Q: Will this work on wood stove pipe joints?**
A: This stuff works like aluminum foil wrapped in a tape.

**Q: Insulation vs conduction: does this tape conduct heat or insulate it? description mentions "conductive" properties. any insulation properties?**
A: I serious doubt it has any insulation properties, you could use to tape air duct but the wood stove pipe I tape up , got extremely hot and that fell off. I probably should have wrapped more time but it's metal tape it will absorb whatever temp it's around
