I am currently sourcing material for a project I want to get started. This will be my first time working with sintra pvc foam, so I have no experience with purchasing. Mcmaster-Carr sells Lightweight PVC Foam sheets, which I assume is the same material. I also found FoamBoardSource.com, who sells name brand sintra. Both allow me to buy a couple square feet at what seems like a reasonable price. My question is concerning the quality of material? As I said, I have never worked with this before and i want to be sure I am getting a good quality product. Am I on the right track? Other suppliers I should look at before I order? I would really appreciate a little direction from some one with experience with this material.
