Re: Is Black Acrylic Conductive?

Hi,

I too think many shiny hard black decorative plastics are fine.  I don't 
think they use anything conductive in these more refined materials.  If you 
have any high voltage source, you can always try a little test.

Black dull plastics, where the black rubs off, like they use for garden 
sheeting and some plumbing piping is the problem.  They use carbon to 
protect against UV.  I am not sure about those black plastic "UV" tyewraps...

When in doubt, test it first.

Cheers,

         Terry
