      In addition to Insulation's Dielectric Constant there is another
      important property called Dissipation Factor. It deals with how quickly
      the Voltage potential stored in the insulator is released. Matthew Bond
      of Tara Labs did a nice "white" paper on it that used to be available on
      their website.

      A third property to consider is the insulator's permeability. If the
      insulator material will absorb moisture or gases its Dielectric &
      Dissipations Numbers can go up.....and in this case up is bad.

      You can go to the matweb site http://matweb.com/index.asp?ckck=1 and
      find out more than you ever want to know. For example you can look up
      the materials, steatite, micalex phenolic plastic, etc. used to make
      tube sockets. It will make you wonder why you have been saving all those
      white ceramic (steatite) tube sockets.
