What would you do if there was no vinyl electrical tape?
If you’re an electrician or a contractor, life without this sticky companion might sound like a nightmare, but for those living just 100 short years ago it was a reality, because electrical tape simply didn’t exist.
In fact, the vinyl electrical tape that we all know and love came into existence more than 70 years ago, when 3M inventors Snell, Oace, and Eastwold created it and saved electricians from the weak, corrosive and rot-prone tape of yore, which was made of tar-coated cotton with a vulcanized rubber adhesive.
