LIQUID CRYSTAL POLYESTER RESIN COMPOSITION, MOLDED ARTICLE, AND OPTICAL PICK-UP LENS HOLDER

摘要

PROBLEM TO BE SOLVED: To improve specific rigidity and vibration-proofing property of a molded article in a liquid crystal polyester resin composition applied to an optical pick-up member.

SOLUTION: The liquid crystal polyester resin composition includes 15-30 pts.mass of a plate-like filler and 5-18 pts.mass of a hollow filler and 100 pts.mass of a liquid crystal polyester having a flowing starting temperature of 360°C or higher. Thus, the specific modulus of elasticity and loss coefficient of the molded article comprising the liquid crystal polyester resin composition can be enhanced. As a result, the molded article excellent in the specific rigidity and the vibration-proofing property can be provided, and it can be preferably used for a bobbin of the optical pick-up lens holder.
