What is the purpose of Fillers in SO Cord

For example, most of the SO cord I've worked with either have paper filler or a hybrid of some fiberglass strands wrapped in paper. Is the *filler* meant as a spacer between the cords inside to dissipate heat ?


On the latter, was just working with some SEOOW 10/3 cable today. No filler at all. Just the 3 wires, all blanketed with some sort of powder as the *filler*

Maybe that is there to act a lubricant between the wires when you bend them back and forth. Even romex has bits of paper around the wires.
