摘要：
An improved polishing pad material is produced by modifying conventional poromeric materials in which a porous thermoplastic resin matrix, typically polyurethane, is reinforced with a fibrous network such as a felted mat of polyester fibers. The polishing material is modified by coalescing the resin among the fibers, preferably by heat treatment, to increase the porosity and hardness of the material as well increasing the surface activity of the resin. The polishing material may also incorporate polishing aids such as particulate abrasives and may also be used as a lapping or grinding material.
