That's like saying Mylar tape. Mylar, or in this case Kapton is the base carrier. The type of tape in the link has copper foil is attached to the Kapton base, so in that particular case, it IS conductive. But the base material, Kapton like Mylar, is NOT conductive.
Kapton can have a carbon dust applied which IS conductive. Mylar can have Iron Oxide applied, which is better known as recording tape. The only use I've ever seen for Kapton tape is high temperature masking for example, in powder coating fusing around 400 degrees F. 73, Charlie k3ICH To: Mark Petiford <rv6am...@yahoo.com>; elecraft@mailman.qth.net Subject: Re: [Elecraft] KX2 Battery Question I'll just reply with https://www.kaptontape.com/Conductive_Tapes.php I last used it in the IFE industry. There may be more than one type, but I'm not an expert at this. 73, matt W6NIA On 05/27/2017 03:31 PM, Mark Petiford wrote: > RE: Kapton tape > > > Matt, > > > Kapton is actually a pretty good insulator, but it is NOT a good > material to prevent abrasion.
