LIQUID CRYSTALLINE POLYESTER RESIN COMPOSITION |
| 摘要 |
A liquid crystalline polyester resin composition has high strength and low warpage due to the reinforcement effects of a filler, high toughness to be resistant to pin press-fitting, good tribological property and good flexural fatigue characteristic. The liquid crystalline polyester resin composition includes 100 parts by weight of a liquid crystalline polyester (A) having a ratio (a)/[(a)+(b)] of an amount of terminal hydroxyl group (a) to a sum of the amount of terminal hydroxyl group (a) and an amount of terminal acetyl group (b) which is 0.70 to 1.00; and 10 to 100 parts by weight of a mica (B). The mica (B) included in the liquid crystalline polyester resin composition has a volume-average particle size of 10 to 50 μm. The mica (B) has an aspect ratio of 50 to 100. |

1. A liquid crystalline polyester resin composition comprising:
100 parts by weight of a liquid crystalline polyester (A) having a ratio (a)/[(a)+(b)] of an amount of terminal hydroxyl group (a) to a sum of the amount of terminal hydroxyl group (a) and an amount of terminal acetyl group (b) which is 0.70 to 1.00; and 10 to 100 parts by weight of a mica (B), wherein the mica (B) included in the liquid crystalline polyester rein composition has a volume-average particle size of 10 to 50 μm, and the mica (B) has an aspect ratio of 50 to 100. |
