SABIC PC Lexan 4701R的概述:
Standard High Heat Moderate Heat Resistance:
Our standard heat resistance grades offer a range of products suitable for moderate heat applications. These materials are based upon a unique polycarbonate copolymer technology that offers improved heat resistance and excellent impact performance. The Lexan XHT product portfolio offers even higher heat resistance and better processability for more demanding applications.

SABIC PC Lexan 4701R的加工:
1.熔融温度高,粘度高,大于200g的塑件,宜用加热式的延伸喷嘴。
2.冷却速度快,模具浇注系统以粗、短为原则,宜设冷料井,浇口宜取大,模具宜加热。
3.料温过低会造成缺料,塑件无光泽,料温过高易溢边,塑件起泡。模温低时收缩率、伸长率、抗冲击强度高,抗弯、抗压、抗张强度低。模温超过120度时塑件冷却慢,易变形粘模
SABIC PC Lexan 4701R的应用:
聚碳酸酯可以满足汽车内饰件对材料韧性、强度、耐热等方面的高性能要求。这些材料在汽车内饰件上的应用,具有以下其它类材料不可替代的优点:
1) 优越的抗冲击性,冲击强度在热塑性塑料中名列前茂;
2) 良好的涂饰性和对覆盖膜的黏附性;
3)高度的尺寸稳定性;
4)将部件安装整合成一体;
5)设计和加工极具灵活性应用。
