PREPARATION METHOD OF POLY-URETHANE MOUNTING PAD

摘要

PURPOSE: A method for manufacturing a polyurethane support pad is provided to uniformly perform a polishing process with high efficiency and to uniformize a thickness, pressure, or tension in a pad region. CONSTITUTION: A resin composition with polyurethane resins and DMF solvents is wet-congealed. A wet congelation is cleaned and dried. The surface of the wet congelation is polished. An adhesive layer is formed on the surface of the polished wet congelation. The wet congelation with an adhesive layer is thermally treated.
