I bought a small piece of the HDPE listed above on Amazon to test it out. I agree that it would probably be alright for cabinet sides but it is certainly not scratch resistant enough for the CP top. I'm actually going to use the small piece I have for the reveals under my CP. It has a sheen that is a close match for the Formica black-matte laminate that I selected for the rest of my cab, but the surface had a few noticeable imperfections. It is really flexible, so it might be nice in situations where you are going around small radii. It routes as easily as laminate and sticks to mdf with contact cement. One side of the HDPE from the seller linked above is super high gloss and the other is matte with a very slight texture.
