Abstract
A polyurethane foam which is obtained from an inert gas and a polyurethane reaction composition containing a polyol component, a foam stabilizer, a catalyst and an isocyanate component, by a mechanical froth method, wherein: the polyol component contains a polymer polyol having a solid content of from 20% by weight to 43% by weight; and the polyurethane reaction composition contains an acid-modified polyolefin powder.

A polyurethane foam, obtained from an inert gas and a polyurethane reaction composition containing a polyol component, a foam stabilizer, a catalyst and an isocyanate component, by a mechanical froth method, wherein:
- the polyol component contains a polymer polyol having a solid content of from 20% by weight to 43% by weight,
- the polymer polyol includes a polyether polyol to which acrylonitrile or styrene has been graft-polymerized,
- the polyurethane reaction composition contains a polyolefin powder that has been modified by a maleic anhydride,
- a mixing ratio of the inert gas is from 31% by volume to 91% by volume relative to 100 parts by volume of the polyurethane reaction composition excluding the inert gas, and
- a residual compression strain of the polyurethane foam based on JIS K6401:
- 2011 is 10% or lower.
