Depron like with smooth face needed

[salvaCNC]

I would like to find a XPS foam like Depron but with smooth face. I found a piece of board that looks like it has been coated with polyethylene.

Thanks

I am not familiar with Depron, but from what I could find about it is quite thin. The Dow High load XPS foams have a hard shell on them, but they start at 1" thickness and work up from there.
Here is a link to Dow.

Hope this helps
