沙伯 PC/ABS CX7240 是一种最广泛使用的工业热塑性塑料。PC/ABS 提供最理想的性能PC优越的强度和耐热性能和ABS的灵活性。沙伯 PC/ABS CX7240的特点：
1、综合性能较好，冲击强度较高，化学稳定性，电性能良好.
2、与372有机玻璃的熔接性良好，制成双色塑件，且可表面镀铬，喷漆处理.
3、有高抗冲、高耐热、阻燃、增强、透明等级别。
4、流动性比HIPS差一点，比PMMA、PC等好，柔韧性好。
5、用途：适于制作一般机械零件，减磨耐磨零件，传动零件和电讯零件.
6、同PVC（聚氯乙烯）一样在屈折处会出现白化现象。
典型应用范围:
汽车内外饰：仪表板，饰柱，仪表前盖，格栅，内外饰件 2.商务设备机壳和内置部件：笔记本/台式电脑，复印机，打印机，绘图仪，显示器 3.电信，移动电话外壳，附件以及智能卡（SIM卡）： 4.电器产品，电子产品外壳，电表罩和壳体，家用开关，插头和插座，电缆电线管道 5.家用电器，如洗衣机，吹风机，微波炉内外部件等。
