Title:
WHOLLY AROMATIC LIQUID CRYSTAL POLYESTER RESIN COMPOSITION AND CAMERA MODULE COMPONENT INCLUDING INJECTION-MOLDED ARTICLE OF SAME AS CONSTITUENT MEMBER
Document Type and Number:
WIPO Patent Application WO/2015/083759
Kind Code:
A1
Abstract:
The present invention makes it possible to obtain a wholly aromatic liquid crystal polyester resin composition with which it is possible to mold a camera module component in which the number of particles that occur when a mobile terminal device such as a smartphone equipped with a camera suffers an impact or falls is low. The invention is implemented by means of a wholly aromatic liquid crystal polyester resin composition that can be obtained by melt-kneading 50-80 mass% of a wholly aromatic liquid crystal polyester, 10-30 mass% of whiskers, 0.5-5 mass% of carbon black, 0-20 parts by mass of talc, and 3-20 parts by mass of precipitated barium sulfate (together, the above constitute 100 mass%), and is characterized in that the heat deflection temperature is at least 220°C, and the melt viscosity at a shear rate of 100 sec-1 and a melting point of +10°C is 20-100 Pa·s.
