[QUOTE="John Burgess, post: 4888984, member: 105098"]kind of complicated I guess, but also kind of scientific. take a flip or a piece of a flip and put it in a glass with 2 tablespoons of salt dissolved in 8 ounces of water. If it stays on the bottom it is PVC. If[B] [/B]it floats it is polyethylene terephthalate (PET) and PVC free. PVC sinks, Non-pvc containing plastics float. this doesn't work with plastics that are trapping air then PVC might float of course. usually in many cases, you can tell by feel, if it's soft an pliable doesn't break or tear without a lot of force, it's got PVC as a plasticizer. if it's hard, rigid and brittle, it's non-pvc. Not sure if the water test works for every composition out there, but it works with flips I've tried, or the windows on 2x2s if it was in question. if it's sinks, get rid of it.[/QUOTE]
