| titleOfInvention | Method for producing polyurethane foam |
| abstract | An object of the present invention is to provide a method of manufacturing a polishing pad having substantially spherical bubbles and excellent in thickness accuracy. Disclosed is a process for producing a bubble-dispersed urethane composition, which comprises the steps of preparing a bubble-dispersed urethane composition by a mechanical foaming method, and a step of dispersing the bubble-dispersed urethane composition (11) in a substantially central portion in the width direction of the face material (A) And a step of uniformly adjusting the thickness of the bubble-dispersed urethane composition by the thickness adjusting means (15), and a step of uniformly adjusting the thickness of the bubble- A step of forming a polishing sheet made of a polyurethane foam by further curing the bubble-dispersed urethane composition having the thickness adjusted in the previous step without applying a load, and a step of cutting the polishing sheet ≪ / RTI >n n n n A polishing pad, a bubble-dispersed urethane composition, a polishing sheet, a planarizing process, a polyurethane foam |
