MOLDED RESIN PRODUCT INCLUDING WHOLLY AROMATIC LIQUID CRYSTAL POLYESTER RESIN CAPABLE OF REDUCING DIELECTRIC LOSS TANGENT BY HEAT TREATMENT, AND ELECTRIC/ELECTRONIC COMPONENT

Document Type and Number:

WIPO Patent Application WO/2020/003690

Kind Code:

A1

Abstract:

[Problem] To provide a molded resin product including a wholly aromatic liquid crystal polyester resin, the molded resin product having high heat resistance and an extremely low dielectric loss tangent even at high frequency bands. [Solution] This molded resin product, which includes a wholly aromatic liquid crystal polyester resin and is formed by heat treatment, is characterized in that an enthalpy change ΔH1 at a melting point of cycle 1 in a heating process and an enthalpy change ΔH2 at a melting point of cycle 2, which are measured with a differential scanning calorimeter, satisfy ΔH1/ΔH2≧2.0, and a dielectric loss tangent measured with the SPDR method at a measuring frequency of 10 GHz is 0.85×10-3 or less.
