Abstract:
The invention provides a liquid crystalline polyester composition, at least containing100 parts by weight of liquid crystalline polyester and 10 to 100 parts by weight of glass fiber, wherein the glass fiber has a weight-average fiber length of 30 to 100 µm, and content of specific glass fiber having fiber length of 300 to 500 µm is 0.1 to 5 percent by weight to a total amount of the glass fiber.
Abstract:
The invention provides a thermoplastic resin composition, comprising 0.1 to 20 parts by weight of a carbon black relative to 100 parts by weight of a thermoplastic resin, wherein the carbon black is dispersed in the thermoplastic resin composition to have a maximum particle diameter of not greater than 50 µm.
Abstract:
The invention provides a liquid crystalline polyester composition, at least containing 100 parts by weight of liquid crystalline polyester (A) and 10 to 100 parts by weight of talc (B). The talc (B) in the composition has a ratio (a1/a2) of oil absorption (a1) ml/100g to specific surface area (a2) m 2 /g in a range of 14.0 to 26.0 (ml·g)/(100g·m 2 ) and has a number-average particle diameter of 10 to 30 µm.
Abstract:
A liquid crystal resin comprises structural units derived from at least two types of aromatic diols. The liquid crystal resin generates 100 ppm or less of acetic acid gas, less than 20 ppm of phenol gas, and less than 100 ppm of carbon dioxide gas when the liquid crystal resin is retained at a melting point +10°C (or at 335°C when the melting point is less than 325°C) for 30 minutes in a helium gas atmosphere. The present invention provides a liquid crystal resin or a composition containing this resin by which metal corrosion, clouding of glass, bulging of molded articles, and the like are reduced.
