dear all,
here is a usefull info about plastics electrical parameters in low freq.
does anybody know same data in high freq?
specially, I am looking for PVC: It seems it has a er=3.2, and loss tan of .001; but some people told me it has a more loss on high frequencies;
yours,
Mat
If i not remember really wrong - temperature is important if material
change phase form, ie. going from crystalin to clear form (light smokie
transparence for plastics in crystallin form, fully clear in amorf form in
higher, close to melting temperatur)
teflon is very much crystallin plastic (white colour) and polyeten i no
crystallic plastic (full clear) for example.
I have weak remember is PCV-cable not good in high temperatur
enviroment (> 80 degree Celcius) - is electric parameter change
to much compare to normal room temperatur...
