NEC-LIST: Hi Q inductors and PVC

Eric,
 
Since PVC has a high dielectric loss factor (compared to other insulation
materials) I wouldn't recommend it as an insulator between coil windings,
especially when the interwinding voltages wil reach hundreds of volts,
although it might give a spectacular meltdown...
 
Some of the industrial applications of RF PVC welding are: stationary goods
such as binders, medial apps such as infusion and blood bags, inflatable
toys such as boats, swimming aids etcetera. This high dielectric loss factor
will also lower the Q of your coil compared to other insulating materials
with a lower DLF, indeed there's more to good RF engineering than high Q...
 
Yes, I used to work in the RF PVC welding area.
 
Regards,
 
Waldemar
