Patent ID: 8859632

Claim:
A shape-formable resin foam comprising: a flexible polyurethane foam obtained by foaming and hardening a starting material which comprises: two or more kinds of polyether polyols including a polyether polyol (A) which has a hydroxyl value of 200 to 500, a content of said polyether polyol (A) being in the range from 45% to 85% by weight based on 100% by weight of the total of said two or more kinds of polyether polyols; a polyisocyanate; and a foaming agent, a glass transition temperature of the shape-formable resin foam being in the range from 15° C. to 35° C., the glass transition temperature being expressed as a temperature corresponding to a peak value of loss tangent (tan δ), said loss tangent (tan δ) being obtained by a following formula: tan δ= G″/G′ wherein G′ is storage modulus and G″ is loss elastic modulus, each of the storage modulus (G′) and loss elastic modulus (G″) being measured at a temperature range from −80° C. to 130° C., at a heating rate of 6° C./minute and at a frequency of 1 Hz, said loss tangent (tan δ) at a temperature of 10° C. to 35° C. being in the range from 0.20 to 0.80, and a ratio (G′ max /G′ mm ) between the maximum value (G′ max ) and the minimum value (G′ min ) of the storage modulus (G′) at a temperature of 10° C. to 35° C. being in the range from 3.0 to 30.
