Excuse me, but what is “PI”?

My needs:

thickness: 3 - 10 mil

quantity: 1 sq ft

single-sided, thickness of copper isn’t important

What about Kapton? You can get copper-clad stuff like [this.](http://cgi.ebay.com/KAPTON-COPPER-CLAD-003-x12-x24-2-SIDES-5574-/230618168787?pt=LH_DefaultDomain_0&hash=item35b1e9fdd3)

Thank you Michael, that’s exactly what I need. But the seller doesn’t ship to my country. :confused:

I searched eBay and found another seller who sells kapton copper clad ( http://cgi.ebay.com/Flexible-copper-cla … 012wt_1165 or just search for Pyralux). I think he has better price and also single sided is better for me.
