CELLULAR STRUCTURES AND VISCOELASTIC POLYURETHANE FOAMS

摘要

The present invention discloses a structure comprising a plurality of three dimensional cells, wherein each cell comprises exterior walls defining an interior void wherein the walls comprise a plurality of struts and windows, the struts forming borders for the plurality of windows, wherein the struts have a plurality of pores. The present invention further discloses a viscoelastic foam having a ratio of elastic modulus (E′) at 20° C. to 25% compression force deflection (CFD) of 25 to 125.
