What exactly is Kapton tape question mark. What can be used as a substitiure question What can be used as a substitute for Kapton. Is it a brand name question marka It's used in my macbook pro to secure wires and ribbon cables.

I went to Fry's to buy some, but couldn't find any. I Didn't have the name of this tape at the time.

I asked severql employees, as well as a couple of customers about this tape and nobody had ever heard of it.

It only took a few seconds to find the name of the tape online. No such luck in the real world.
