Polyurethane composition and polishing pad |
| abstract |
A polyurethane composition comprising a dispersion of solid beads in a polyurethane, wherein the polyurethane is a polyurethane fine foam having fine bubbles, and a polyurethane having a storage modulus at 40 ° C. of 270 MPa or more measured by a dynamic viscoelasticity measuring device. The polishing pad using the composition is excellent in flatness. Further, as a polyurethane composition comprising dispersion-containing solid beads in a polyurethane, a polishing pad using a polyurethane composition in which the solid beads are solid beads that swell or dissolve in an aqueous medium can achieve both flatness and uniformity. In addition, scratches can be reduced. |
