Is Glue a good insulator?
It is a good insulator, and it is also strong for phone charging cables, etc. However what I learned with boards, such as inside an adapter for my computer, is that the hot glue, when applied can melt parts of the board and cause damage. So keep that in mind when using it.
No, CA glues are not conductive. They're really just a polymer just like any other plastic. The bigger concern would be getting glue on the contacts that would prevent a good connection. Cyanoacrylate adhesive ("unfilled" that is without carbon oder metal particle filling) is typically not conductive.
- While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor than both of them by mass due to its very low density.
- Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics, but vinyl is most popular, as it stretches well and gives an effective and long lasting insulation.
- Duck tape isn't even good enough for ducts. In fact, don't use duct tape for ANYTHING. If you're trying to cap the exposed end of a wire, use a wire nut. If you're using a bare wire for some crazy reason and you want it coated, replace the wire with an insulated one or use heat-shrink tubing.
