Where Can I Find Polymer Blend Sheets for Testing Applications?

[refind]

I'm looking to get some polymer blend sheets for some tests. Something like PC-ABS or PMMA-PC or something of that nature. Basically a mix of 2 polymers but NOT a co-polymer. Just a simple mix. I looked all over and haven't found anyone selling it. Thanks!

While I am far from a specialist in polymers, I have been doing a little reading into them as my company is thinking about using polymers to replace existing materials. Might I suggest asking in the chemistry forum or chemical engineering?
If it's not sold then maybe there isn't a market for it. i.e. There are more superior polymers.
