PC 用途

宽波透光的光学器械，作为一种透明性能良好的工程塑料，PC作为光盘基材在全球大量使用，不仅可以制备CD、VCD、DVD光盘，还可以适用于高密度记录光盘的基材，尤其是PC与苯乙烯接枝生成的共聚物具有极佳的应用效果。PC片材特别适宜于制作眼镜镜片，在PC分子链中引入硅氧基团，可以提高其硬度及耐擦伤性。PC作为高折射率塑料，用于制作耐高温光学纤维的芯材，若在PC分子链中的C—H 链为C—F链所取代，则可以对可见光的吸收减少，能有效降低传递途中的信号损失。另外PC良好透光性，在透明窗材高层建筑幕墙、机场和体育场馆透明建筑材料等方面应用非常普遍和具有潜力，今后重点是提高表面硬度和抗静电性。　　阻燃环保的通信电器，由于PC良好电绝缘性能，广泛应用于通信电信设备领域，目前PC已经大量替代原有的酚醛塑料，今后重点开发阻燃PC用于通信电器领域中，因此无污染阻燃PC材料成为开发重点，溴系阻燃剂由于毒性在减少使用，而无卤环保磷系阻燃剂会明显降低PC的热变形温度和冲击强度，因此比较适宜的是有机硅系阻剂。另外随着通信电器轻量小型化对PC材料提出更高要求，目前 PC/ABS合金就特别适宜在通信电器及航空航天工业中应用。　　表面金属化的汽车部件，分子链中的C—H 链为C—F链所取代，则可以对可见光的吸收减少，能有效降低传递途中的信号损失。另外PC良好透光性，在透明窗材高层建筑幕墙、机场和体育场馆透明建筑材料等方面应用非常普遍和具有潜力，今后重点是提高表面硬度和抗静电性。

　　阻燃环保的通信电器，由于PC良好电绝缘性能，广泛应用于通信电信设备领域，目前PC已经大量替代原有的酚醛塑料，今后重点开发阻燃PC用于通信电器领域中，因此无污染阻燃PC材料成为开发重点，溴系阻燃剂由于毒性在减少使用，而无卤环保磷系阻燃剂会明显降低PC的热变形温度和冲击强度，因此比较适宜的是有机硅系阻剂。另外随着通信电器轻量小型化对PC材料提出更高要求，目前 PC/ABS合金就特别适宜在通信电器及航空航天工业中应用。

　　表面金属化的汽车部件，PC表面金属化后具有良好的金属光泽及高强度，广泛应用于各种汽车零部件中，但是电镀过程中会降低它的冲击韧性，因此采用弹性体与 PC共混改性，所合弹性体分散了致开裂应力，虽经电镀也不会降低其冲击韧性，因此电镀级PC树脂非常具有开发前景。另外表面金属化的PC还可以作为电磁波的屏蔽材料，应用于计算机中。

　　低残留有害物的食品容器，工业合成PC是双酚义型，由于合成时有微量未反应的单体双酚A残留在树脂中，在作为饮用水桶和食品容器时，易被溶出而影响人们身体健康，因此要开发卫生级的PC树脂，用作饮水桶和其他食品容器的生产与使用，国内应用前景非常看好。

　　防开裂脆化的医疗器械，PC具有诸多优异性能，目前已应用于医疗器械中，由于其耐化学品性较差，在化学药品存在下易引起内应力开裂，如PC在人工透析器、人工肺等医疗器械中应用要解决高温消毒导致裂纹的老化现象，若克服这些缺点，PC在医疗器械中应用可迅速扩大。

　　聚碳酸酯薄膜及片材 PC FILM & SHEET 主要成份为进口的聚碳酸酯（PC)树脂 可应用于光学、控制面板、遥控面板、液晶显示屏窗口、标签铬牌、汽车仪表板，薄膜开关，电容器电容介质、录音带、彩色录像磁带等。
