3D-printed "superfoam" absorbs up to 10 times as much energy as conventional padding; may have use in automotive and defense applications

Providing energy absorption 10000yrs into the future, even at the edge of a subduction zone. No more plate tectonics for you.

Unspecified foam usually means polyurethane, and the pics reforce that assumption. So no, it only degrades in response to uv, temperatures (any and all), humidity, and being looked at wrong. Also PU involves some nasty and underregulated chemicals
