Beschreibung
Zusammenfassung:	The present disclosure relates to a liquid crystal polyester resin composition comprising a liquid crystal polyester resin with a low dielectric constant and a low dielectric loss containing a naphthoic acid monomer as a main skeleton and a hydroxybenzoic acid; a glass bubble having a pressure resistance of 12,000 psi or more; and an inorganic filler such as mica. The present disclosure provides a liquid crystal polyester resin composition suitable for 5G communication materials, which can achieve low dielectric loss characteristics, and at the same time, the addition of glass bubbles with excellent pressure resistance can achieve a low dielectric constant and a low dielectric loss through the maintenance of the hollow body of the glass bubbles even after melt extrusion.
