Expanded PVC vs Foam Board

I got some Foam Board from Michaels yesterday and was looking up expanded PVC also to build my robot frame and body. They look almost identical online. Both can be cut with knives also. Are they the same thing? and if they are not the same thing would it be better to make the bot first with the foam board then use it as a pattern to cut the expanded PVC?

 

Thanks for your help! :)

foamboard has the pros and cons of the paperboard/cardboard... beeing just a little more rigid,  my experience has shown that it's really great to experiment things with it

 

to make something more durable, go with pvc 

ok cool thanks for the advice.
