Polyethylene Foam

Foams are dipped into molten metal, then placed in a vacuum so that the air in the foam’s pores is removed and replaced by the alloy. The foam had pore sizes of about 2mm, that can be tuned to create a stiffer or more flexible materials. During testing of its strength material showed an ability to deform when heated above 144 degrees, regain rigidity when cooled, then return to its original shape and strength when reheated.
