Today I’ve recieved the PVC ordered some days ago… and suprise !!! is not as I expected, intead of a the foamy sheet it’s surface is like polished. My question is : can I use it for a sandwich board? will I have any problems? wich?
Sounds like you might have PVC as in sign making material. I am attaching a picture of each material. Komatex is the PVC for signs. It can be used for stringers. The green grainy foam is Divinycell. It is what you need for sandwich boards.
