US 2017/0247527 A1 · POLYESTER RESIN COMPOSITION FOR DAMPING MATERIAL

Abstract

A polyester resin composition for a vibration-damping material, containing a thermoplastic polyester resin constituted of a dicarboxylic acid component and a diol component (A), one or more members selected from the group consisting of plasticizers and styrene-isoprene block copolymers (B), and an inorganic filler (C). The polyester resin composition of the present invention can be suitably used as a vibration-damping material for a material for audio equipment such as, for example, speakers, television, radio cassette players, headphones, audio components, or microphones, and manufactured articles such as electric appliances, transportation vehicles, construction buildings, and industrial equipment, or parts or housing thereof.
