拜耳Apec系列PC详细说明

聚碳酸酯(简称PC)是分子链中含有碳酸酯基的高分子聚合物，根据酯基的结构可分为脂肪族、芳香族、脂肪族-芳香族等多种类型。其中由于脂肪族和脂肪族-芳香族聚碳酸酯的机械性能较低，从而限制了其在工程塑料方面的应用。目前仅有芳香族聚碳酸酯获得了工业化生产。由于聚碳酸酯结构上的特殊性，现已成为五大工程塑料中增长速度最快的通用工程塑料。

聚碳酸酯耐弱酸，耐弱碱，耐中性油。

聚碳酸酯不耐紫外光，不耐强碱。

PC是一种线型碳酸聚酯，分子中碳酸基团与另一些基团交替排列，这些基团可以是芳香族，可以是脂肪族，也可两者皆有。双酚A型PC是最重要的工业产品。

PC是几乎无色的玻璃态的无定形聚合物，有很好的光学性。PC高分子量树脂有很高的韧性，悬臂梁缺口冲击强度为600~900J/m，未填充牌号的热变形温度大约为130°C ，玻璃纤维增强后可使这个数值增加10°C。PC的弯曲模量可达2400MPa以上，树脂可加工制成大的刚性制品。低于100°C 时，在负载下的蠕变率很低。PC耐水解性差，不能用于重复经受高压蒸汽的制品。

PC主要性能缺陷是耐水解稳定性不够高，对缺口敏感，耐有机化学品性，耐刮痕性较差，长期暴露于紫外线中会发黄。和其他树脂一样，PC容易受某些有机溶剂的浸浊。
