Title:
POLYESTER RESIN COMPOSITION AND CAMERA MODULE CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP2015028181
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which has excellent heat resistance and low particle property, extremely good dimensional stability (particularly, in dimensional changes accompanying moisture absorption) and which can be molded into a sliding member such as a camera module member, and to provide a component containing the composition, which has a sliding structure such as a camera module.SOLUTION: A polyester resin composition for a sliding member is provided, which comprises: a polyester resin (A) including a dicarboxylic acid component unit (a1) including a dicarboxylic acid component unit derived from terephthalic acid and a dialcoholic component unit (a2) including a component unit having a cyclohexane skeleton, and having a melting point or a glass transition temperature of 250°C or higher; a copolymer (C) having a structural unit derived from an olefin, a structural unit derived from an α,β-unsaturated carboxylate, and a structural unit having a cyclic oxy hydrocarbon structure including a structure derived from an α,β-unsaturated carboxylic acid glycidyl ester; and at least one of carbon black (G) and a fibrous inorganic filler (D).
