viscoelastic foam, polyol composition, reagent system for preparing a viscoelastic polyurethane foam, viscoelastic polyurethane material, and process for preparing a viscoelastic polyurethane foam

摘要

Embodiments of the present invention disclose viscoelastic foams having a renewable natural resource contents of between about 1 and about 25 wt % of the foam. The foams may have a ratio of elastic modulus (E) at 20° C. to 25% compression force deflection (CFD) of 25 to 125.
