    • PROBLEM TO BE SOLVED: To provide a finishing polishing pad that reduces defects such as scratches, particles and the like on a polished mirror surface in polishing, and achieves stable polishing characteristics that reduces surface roughness of the mirror surface to be polished.SOLUTION: The polishing pad is made of two or more kinds of different layers consisting of a polishing sheet (a) and a cushioning layer (b). A top layer of the polishing sheet (a) is a porous polyurethane layer (c) whose principal component is polyurethane obtained by a wet coagulation method. Either of the other layers is a foamed plastic layer (d) whose modulus of compressive elasticity is 0.08 to 0.25 MPa.
    • 要解决的问题:提供一种抛光抛光镜表面上减少诸如划痕,颗粒等的缺陷的精加工抛光垫,并且实现了降低待抛光的镜面的表面粗糙度的稳定的抛光特性。 抛光垫由抛光片(a)和缓冲层(b)组成的两种或多种不同的层制成。 研磨片(a)的顶层是通过湿式凝固法得到的主要成分为聚氨酯的多孔聚氨酯层(c)。 其他层中的任何一个是其压缩弹性模量为0.08至0.25MPa的泡沫塑料层(d)。 版权所有(C)2012,JPO&INPIT
