Dennis,
I was in the construction "bidness" here in Texas for a thousand years and know the lay of the land.  So, finding a source is easy.  This item is installed by specialty contractors now.  If you can find one of these guys, he will have a stack in his warehouse or yard.  Wrong color, size, or removed for a remod.  There are a thousand colors and if the piece is too small they must order another.  I walked by a piece for a year laying in the woods by a walkway into a soccer park.  I finally had to pick it up and put it in my boat building "park".  It came from a remod. of the concession/bath about a hundred yards away and missed the dumpster.  Call a commercial building contractor and ask the estimator where they buy toilet partitions.  Then ask that supplier who they get to install.  Most are furnished "installed" around here....now.  Tell them you just need a small piece of any color.  The point is that you need to get it before the pile gets too big and ends up in the dumpster.  Schools use this type because you can not write on it and paint rubs off and they are kinda ugly colors.

Jib,
 
"Cheaper than dirt" is good! 
I looked on line for "toilet partition discards... and got lots of hits.  Am I understanding you correctly... if I can find one of these places locally, I can go there and they are likely to have discards, that they'd just hand out because its cheaper than them having to dispose of them.  Is that right?

I use HDPE (polyethylene) toilet partition discards.  It is solid throughout and generally 3/4" thick.  It is not UHMW "I think" but it is strong and very slick.  Easy to cut. tap, finish with wood finishing tools.  It is a great material around water and any supplier or installer has more pieces and colors than they need or want......I. E. no money transaction. Cheaper than dirt.

Recycled UHMW is a cheap boaters friend. Here in the US Mcmasters Carr has recycled UHMW in several sizes at reasonable prices, I'm about halfway thru a 3/4" X 5-1/2" X 6' piece that's been used for bearings, fairleads and tip plates (which are a form of bearing plates in my case). I'm not a real fan of PVC pipe (except as clamps) since it lacks stiffness, but have been known to grab a piece and heat flatten the ends when a short reinforcing strut was called for.

cheers,
