Hi Dave:
I need a sheet of plastic that goes between a PCB
and a metal enclosure. This is to make a creepage
spec. What plastics are good for this? Will
polycarbonate be suitable and have a 94V-0 rating?

Dave,
Some interesting comments and discussion so far.
Let me comment that I often use insulation
Thanks to all for your sage comments! We will go with 20 mil Nomex.

I know this is nit picking, but Nomex is a brand of aramid
paper (a nonwoven polyester) and is not vulcanized fiber.
I agree that it's an excellent insulating material,
especially for high temperature applications, though pricier
than other materials equally suited to Dave's particular

Hello Dave,
Nomex paper (sheet stock) will do the trick, I believe.

You don't identify the end-product safety standard, but here
goes.
Not all polymeric materials are created equal, often not
even in the same generic family. Any number of key material
parameters might change with the formulation of the resin.
To be certain you have a material that meets
DuPont Nomex, GE Lexan, and GE Valox

I need a sheet of plastic that goes between a PCB and a metal enclosure.
This is to make a creepage
chassis and
PCB so that any bad SFC will not result in failure of subsequent hi-pot.
luck,
Brian
