Uhhh, no. In fact not all EVA foam is necessarily crosslinked nor is it PE.
The polymer reference materials that I frequently use list the common
materials for closed cell foams separately
PE, EVA,PS, PVC, PP, PPO, PU, etc.
PE is foam made from Polyethylene. EVA is an Ethylene-vinyl acetate
copolymer. Different thermoplastics but both used separately to make
foams and together in blends).
For a quick reference:
