PVC是聚氯乙烯,最常用,便宜。
PC是聚碳酸酯,价格昂贵,强度高,用时长。
1、PVC树脂塑料制品突出优点是难燃性、耐磨性、抗化学腐蚀性、气体水汽低渗漏性好。此外综合机械性能、制品透明性、电绝缘性、隔热、消声、消震性也好,是性能价格比最为优越的通用型材料。缺陷是热稳定性和抗冲击性较差,无论是硬性还是软质PVC使用过程中容易产生脆性。
2、P C(聚碳酸酯)树脂是一种性能优良的热塑性工程塑料,具有突出的抗冲击能力,耐蠕变和尺寸稳定性好,耐热、吸水率低、无毒、介电性能优良,是五大工程塑料中唯一具有良好透明性的产品,也是近年来增长速度最快的通用工程塑料。
The outstanding advantages of PVC resin plastic products are flammability, wear resistance, chemical corrosion resistance, and low leakage of gas vapor. In addition, comprehensive mechanical properties, product transparency, electrical insulation, thermal insulation, muffler, and shockproof are also the most versatile materials with superior performance prices. Defects are poor thermal stability and impact resistance, and it is easy to produce brittleness during the use of hard or soft PVC.
2, PC(polycarbonate) resin is a kind of excellent thermoplastic engineering plastic, with outstanding impact resistance, good creep resistance and dimensional stability, heat resistance, low water absorption, non-toxic, good dielectric properties, It is the only product with good transparency among the top five engineering plastics and the fastest growing general-purpose engineering plastics in recent years.
