A liquid-crystalline-polyester resin composition for camera modules

Title:

A liquid-crystalline-polyester resin composition for camera modules

Document Type and Number:

Japanese Patent JP5951167

Kind Code:

B2

Abstract:

To provide a resin composition, which is excellent in the balance between heat resistance, rigidity, moldability and surface exfoliation characteristics, for a surface-mountable (SMT) camera module.

The liquid crystal polyester resin composition comprises 50-110 pts.mass of talc having a number-mean particle diameter of 10-50 μm, and 2-10 pts.mass of carbon black based on 100 pts.mass of a liquid crystal polyester. The liquid crystal polyester resin composition exhibits melt viscosity of 10-150 Pa s as determined at a shear rate of 100 sec-1at 370°C and a deflection temperature under load of 220°C or above.
