LIQUID CRYSTAL POLYESTER COMPOSITION, REFLECTIVE PLATE AND LIGHT-EMITTING DEVICE

摘要

PURPOSE: A liquid crystal polyester composition is provided to manufacture a reflective plate having high reflexibility. CONSTITUTION: A liquid crystal polyester composition comprises liquid crystalline polyester, white pigment, and a bundle of glass fibers. The bundle of glass fibers is formed by focusing glass fibers by a sizing agent. The sizing agent comprises polyurethane having a polyester polyol unit and at least one unit among an aliphatic diisocyanate unit and an alicyclic diisocyanate unit. The polyester polyol unit is a polyol unit having an aliphatic polyvalent alcohol unit, and at least one unit among an aliphatic polybasic acid unit and an alicyclic polybasic unit.
