Friction tape is for just the opposite. That is, increasing friction. In this case, the word “friction” is a synonym for “grip”.
When you need to insure a slip proof grip on a tool, say a hammer handle, or a piece of sports equipment, the tacky feel of friction tape makes something easier to hold on to.
Friction tape is made a little differently than other tapes. Instead of having the adhesive laminated on one side of the tape, friction tape is actually impregnated with a rubber based adhesive, so that it is sticky on both sides.
