Abstract: A polishing pad for surface planarization is made by impregnating a polyester-based fibrous fabric with thermosetting resins to form a porous impregnated material, and heating the porous impregnated material to effect changes in shape of the pores such that an integrally formed polishing pad with hard/soft layers of different hardnesses is obtained; the heated side of the polishing pad has high hardness and high cutting/grinding ability, whereas the unheated side maintains the original tiny pores and low hardness; and the polishing pad can produce a buffering effect when subjected to an external force and in turn apply an evenly distributed force to an article being polished.

Abstract: A low shrinkage low oligomer polyester film and a method for manufacturing the same are provided. The method includes forming at least one polyester composition into an unstretched polyester thick film and stretching the unstretched polyester thick film in a machine direction (MD) and a transverse direction (TD) at a stretch ratio of two to six times. The polyester composition includes 94% to 99.974% by weight of a polyester resin, 0.01% to 1% by weight of a primary antioxidant, 0.01% to 1% by weight of a secondary antioxidant, 0.003% to 2% by weight of a nucleating agent, and 0.003% to 2% by weight of a flow aid. The polyester resin has an intrinsic viscosity between 0.60 dl/g and 0.80 dl/g.
