I wonder if the outer sides have been painted and the surface is the result of a reaction with a paint?
Elapor is much different from EPP, especially as it is molded, rather than cut from a block.
The surface of your sample looks rather rough however. It should be a bit smoother. No paint is used in the process. The hot wire cutting emphasizes the color of the foam.
