I just went to AIN Plastics today looking for some coroplast, but the lady at the store recommended expanded PVC or Polycarbonate. PolyCarb is more expensive and more durable, but I have to spend a minimum of $75 anyways (store policy) which will give me enough of both, and I'm not really worried about scratches or dents.
The PVC is very flexible and it doesn't snap when folded to extremes. When heated, it seems to crease instead of curve. I'm not really concerned about this, it's flexible enough to curve when not heated. I'll just have to make sure to force it into place with a strong frame.
Does anyone here have any tips regarding these materials?
