LIQUID-CRYSTALLINE POLYESTER BLEND COMPOSITIONS

摘要

PURPOSE: A liquid crystal polyester blend composition is provided to ensure excellent mechanical and thermal properties, and very low dielectric loss tangent in a high frequency band. CONSTITUTION: A liquid crystal polyester blend composition comprises 100.0 parts by weight of liquid crystal polyester blend and 0.1-300 parts by weight of calcium titanate and/or barium titanate. The liquid crystal polyester blend is obtained by blending liquid crystal polyester A(LCP A) and liquid crystal polyester B(LCP B) so that a weight ratio of (LCP A) / (LCP B) become 99/1 - 80/20.
