級(jí)別：特級(jí)

　　形態(tài)：顆粒

　　特性：

　　1、耐沖擊性

　　于工程塑料中，算是有**優(yōu)良之耐沖擊性能之樹脂

　　2、透明性

　　可視光線之透光率達(dá)80-90%，與聚丙烯樹脂(PMMA)之透光率大致相同

　　3、成型尺寸穩(wěn)定

　　聚碳酸酯屬于非結(jié)晶性樹脂，成型收縮率小，成型尺寸穩(wěn)定性佳。另外，蠕動(dòng)變形及吸水尺寸變化等較小，加上成型尺寸穩(wěn)定，適合精密成形品。

　　4、難燃性

　　聚碳酸酯之自熄性能佳，適合電器制品、汽車、建材等應(yīng)用。

　　5、耐候性

　　聚碳酸酯之耐候性(耐紫外線性)優(yōu)良，可用于戶外用途、汽車車燈等。

　　6、無毒性

　　不含一般可塑劑等添加劑，不含毒性，可用于食用器具、醫(yī)療用品等。另外，亦備有FDA認(rèn)可之型號(hào)。

　　7、電氣特性

　　于廣泛的應(yīng)用溫度范圍，電氣特性之變化亦不大，絕緣性佳。
