What is this material?

I received some practice materials from a nearby sign shop. Can anyone help me with what this is? Shiny on both sides - super light weight. Thanks!

the edge looks kind of like PVC with those pores (bubbles in pvc), but it could also be HDU with a coating on the faces.

If I’m correct it’s sign foam. Nice stuff

high density urethane (signfoam.com)

oops , sorry @SethCNC


no need to be sorry. We’re on the same page, I’m pretty sure its HDU, especially since she got it from a sign shop.

I’m sure the full name, the link and the photos there will help Susan determine. :+1: :+1:
