Home Depot's 100% cellular PVC: Similar to HDU ?

(Not sure if I placed this thread in the right forum. God. So many of them ...)

I have been building very detailed ( using 1mm router ) models from MDF, but the pain of sealing and painting it afterwards was too much (apart from the fact that with priming, sanding, priming, sanding, painting sanding, ... half of the details are gone).

Anyhow. I was looking to build my next models in HDU. Never worked with it, though. So I was looking for a local supplier (Markham, Ontario) and stumbled across a "100% cellular PVC" board at Home Depot. It routes ok, sands nicely. Except I sometimes collect burrs around the router and then my precision is gone. Anyone have any thoughts ? ("Go to HDU immediately" or such)

By the way: If someone has tiny HDU scraps kicking around, I'd really like to try them ( 0.5" x 3" x 1.5" is enough, will pay for shipping of course). But I'll post that in the "Wanted" forum ...

Thanks, guys !

Shucks woodlee! I just don't understand any of the alphabet soup except for PVC (if that means polyvinyl acetate)

PVC = Polyvinyl Chloride (http://en.wikipedia.org/wiki/Pvc)
HDU = High Density Urethane foam (http://www.woodsigns.com/HDU.htm)

Woodlee,
Until your post I had never heard of HDU and have no scraps for you.
I am curious about these detailed models, how about posting a few photos?
