  • Polyurethane foam and polishing pad
    Patent number: 8557005
    Abstract: The present invention provides a polyurethane foam, which, despite having a low specific gravity, has a hardness and an elasticity favorable for a polishing pad, and a polishing pad made using the polyurethane foam. The polyurethane foam is obtained by reacting a blend composition containing (A) a polyisocyanate, (B) a polyol, (C) a chain extender with a molecular weight of equal to or smaller than 400, and (D) water, and in the blend composition, MDI is blended as a main component of the component (A) and a blending amount of the MDI is 45 to 70 parts by weight when a total weight of the respective components (A), (B), and (C) is taken as 100 parts by weight.
