PC电绝缘性(尤其高频绝缘性)优良,无色透明,透光率仅次于有机玻璃,着色性耐水性,化学稳定性良好,强度一般,但质脆,易产生应力脆裂,不耐.等.适于制作绝缘透明件.装饰件及化学仪器.光学仪器等零件.
The main characteristics of PC: rigid and tough, high impact resistance, high dimensional stability and wide range of use temperature, good electrical insulation and heat resistance and non-toxic. The PC has excellent performance and good light transmission ability, and its transmittance is close to 90%
PC成型性能 :
1.无定形料,吸湿小,不须充分干燥,不易分解,但热膨胀系数大,易产生内应力.流动性较好,可用螺杆或柱塞式机成型.
2.宜用高料温,高模温,低压力,延长时间有利于降低内应力,防止缩孔.变形.
3.可用各种形式浇口,浇口与塑件圆弧连接,以免去处浇口时损坏塑件.脱模斜度大,顶出均匀.塑件壁厚均匀,不带镶件,如有镶件应预热.
PC的物料性能 冲击强度高,尺寸稳定性好,无色透明,着色性好,电绝缘性、耐腐蚀性、耐磨性好,但自润滑性差,有应力开裂倾向,高温易水解,与其它树脂相溶性差。 适于制作仪表小零件、绝缘透明件和耐冲击零件
关于PC合金的研究与开发日新月异,还有多种PC合金不断被开发并推向市场 ,尤其是聚酯共混改性PC,如PET/PCL(由乙二醇、低分子量聚己内酯和对二共聚而成的多嵌段共聚酯)与PC共混改性;由环已烷二、乙二醇和对二制的聚酯与PC共混改性,可以明显提高PC弯曲弹性模量、拉伸强度等;聚己内酯以玻璃纤维作为增强材料,用酯交换催化剂促进聚己内酯与PC进行共混改性,可以得到加工性能好、高刚性的透明材料;聚酯改性PC,可以明显改善PC的透明性和耐黄变性能,可以用作光盘材料;液晶聚酯改性PC,可以用来改善PC的熔融加工性能和力学性能。
