Page seems about insulation materials (very general) and insulator objects (very specific objects from some related applications).
@ Light current: made a similar point in 2006. The 2016 archive has : "Insulation v insulators - I hesitate to ask, but should these two subjects have separate pages?--Light current 03:36, 28 March 2006 (UTC)"
Article seems to need more on materials - eg when flexibility, high temperature, or corrosion resistance are needed ? eg what materials are used for insulating wires in high temp aerospace applications, or in down-hole applications hot & deep in drill bores/wells. or to insulate electrical motor windings, or high-voltage transformer windings ? What temperatures can PVC or PTFE be used to ? Gutta-percha, cotton ? - Rod57 ( talk) 10:18, 13 June 2021 (UTC)
Sorry for the stupid question, but actually there's something that seems unclear to me. It is said that the electrons of the insulator are bound to their atoms. Fine. So, these electrons can't access the conduction band to participate to the electric flow. Alright. Still, the conduction band does exist. So, if the electric source injects some electrons on the conduction band of the material, what prevents these electrons from progressing on said conduction band? In other words : why should the charge transfer be due exclusively to the electrons that belong to the material? I miss omething....
