Silicone or Acrylic Adhesive?
Your adhesive choice can make a large difference in how your machines perform.
Silicone Adhesive
Rated from -100°F to 500°F (-73°C to 260°C). Less tacky and recommended when temperatures run consistently at or above 350°F.
Acrylic Adhesive
Rated from -40°F to 350°F (-40°C to 177°C). Tackier for lower-temperature work, though it may leave some residue on removal.
Silicone or Acrylic Adhesive?
Your adhesive choice can make a large difference in how your machines perform. If temperatures run consistently at or above 350°F, choose silicone. Below that, acrylic or silicone will work depending on your preference. Download the full data sheet (PDF) for any tape below.

Tapes That Last Longer on the Line
The production team really likes the new blue tape. They said it lasts about twice as long before needing to be changed out.
If you were hoping to hear some good things about the blue weld tape, then I have good news. For our application at least, it works very well. It leaves a little more glue residue on the plate after removing it, but that’s a fairly easy fix, not considered a negative. It is very durable and will actually outlast the other tape, but only if it’s kept really clean. It’s definitely worth the effort; you can get an extra day out of the tape if you can keep it free of foreign materials. All in all, I believe it’s a good quality product, with the bonus that the blue just plain looks cool.

PTFE Tape Frequently Asked Questions
Which adhesive do I need?
Your adhesive choice can make a large difference in how your machines perform. If temperatures are consistently at or above 350°F, we recommend silicone adhesive. Below that, you can choose acrylic or silicone depending on your preference.
What is a liner, and do I want it?
A liner is a paper or plastic cover over the adhesive. It keeps grease and other contaminants on your hands from wearing out the adhesive before you apply it. Narrow tapes work fine with or without a liner. For tapes wider than 5″, we recommend a liner: pull off what you need, cut it from the roll, then peel the liner away from one edge and apply.
Should I get a thicker tape?
Not always. If your tape is burning out early, the cause may be an overheating wire or hot knife rather than tape thickness. Check the heat with an infrared thermometer to make sure temperatures are in spec, and if they aren’t, check your machine settings and electrical components (always follow safe practices on electrical equipment). Thicker tape also reduces heat transfer to the packaging, which can keep it from sealing properly, so step up gradually. Common thicknesses are 3, 5, 6, 10, and 14 mil.
