The main difference between these two materials is that regular foam core has a cardboard coating on both sides of its interior foam, whereas Foam Core Ultra is coated with plastic.
Both materials are lightweight, fairly rigid and are used for the same types of signage.
But you will run into the following problems with regular foam core:
The material is sensitive to damage
Its paper coating is prone to surface imperfections and indentations
It is easily scratched up and bent
It compresses but does not spring back into place
Any amount of moisture will cause permanent damage Even minimal handling can cause damage
Alternatively, with our Foam Core Ultra, you won't need to worry about any of those problems. Foam Core Ultra is plastic coated, durable, waterproof, scratch and dent resistant.
Foam Core Ultra has everything you were looking for in a foam core sign, only more!
