[Amps] Kitchen Aid Silicone for Chimneys

[Kevin LaHaie]

Well, It seems there are issues with using PVC or CPVC close to lots of 
RF, so I now consider it a potentially risky option.

Silicone Sheet, on the other hand, seems to be widely used.  It has been 
available from sources like McMaster Carr (sp?).

BUT

The kitchen departments are now loaded with objects formed from it, from 
cupcake forms to spatulas.

Yesterday I found, at TARGET, a Baking Mat made by Kitchen Aid from the 
stuff - an 11 x 16.6" piece of fairly thick silicone sheet.  With some 
Permatex Red RTV high temp silicone I intend to fashion a GS-35b 
chimney.  Also, I plan to have the chimney come to the top of the anode 
cooler, totally enveloping it, rather than just pushing air into the 
base.  (any comments as to why or why not??)

Main thing here, is it is readily available, not requiring a mail order 
and shipping exercise, or much travel time.  It was $12 with enough 
material for 2 tubes.

Any comments on this material in an RF rich environment?

Thanks, and the chimney thread demonstrates the great value of this 
reflector - lots of great information from knowledgable folks!
