[Amps] RF insulating materials - engineered plastics

[John Lyles]

Dave
It would be nice to have the time and a wide variety of materials to do this. Everyone seems to have a pet material for RF insulators. I did the measurements for materials i use on my job. All were readily available from any plastic supplier in most cities. While not free, small pieces are not going to break the bank either. They are amazing materials, if you need the RF, thermal or mechanical performance. That said, I would be happy to test any samples provide to me as long as they are cut in the same geometry in order to make good comparisons. It is not an absolute but only relative measurement that I did.
