Cotton- the natural enviromentally-friendly insulator that gives better results than Teflon and other plastics. Cotton has a better dielectric constant than Teflon and PE. Use it to insulate copper or silver wire - Sound is a lot more open and less grainy than Teflon. Also great as it dampens vibrations along the cable. Great for speaker cables as well, but you will need to run wire sufficient for the speakers and amp. But well worth it - you will get excellent results. Not recommended for insulating wire to be used as power cables.

Dielectric Constants

Cotton: 1.3 - 1.4

Polypropylene/PP:1.5

Teflon/PTFE: 2

Polyethylene/PE: 2.2 - 2.4
