EPP is a super tough and very light weight foam. EPP is more flexible than Depron and extruded polystyrenes. Items made of EPP will need more reinforcement, but the EPP itself will bend farther before breaking.
These are saw cut or "skived" sheets (kinda like cutting sponge cake with a hacksaw). So, even though we target a certain thickness, the stated thickness is approximate and is not guaranteed to be cut exactly the same on every sheet. Thickness may vary as much � 10%.
