PCTG 一种透明塑料,是一种非晶型共聚酯,PCTG常用的共聚单体为1,4-环己烷二甲醇(CHDM),全称为聚对苯二甲酸-1,4-环己烷二甲醇酯。它是由对苯二甲酸(PTA)、乙二醇(EG)和1,4-环己烷二甲醇(CHDM)三种单体用酯交换法缩聚的产物,与PET比较多了1,4-环己烷二甲醇共聚单体,与PCT比多了乙二醇共聚单体,因此,PCTG的性能和PET、PCT大不相同。 PCTG是一种非结晶型共聚聚酯,随着共聚物中CHDM的增加,熔点下降,玻璃化温度上升,结晶度下降, 形成无定形聚合物。PCTG中CHDM的含量大于50%。
PCTG用途:
板、片材:
使用常规的成型方法,可以制备1~25.4mm厚的透明材料,具有突出的韧性和高抗冲击强度,其抗冲击强度是改性聚丙烯酸酯类的3~10倍,成型性能优异,冷弯曲不泛白,无裂纹,易于印刷和修饰,广泛应用于室内外标牌、储物架、自动售货机面板、家具、建筑及机械挡板等。
PCTG卡主要应用于欧洲,但在北美、亚洲也得到了越来越多的应用。原因是具有很宽的加工范围,高的机械强度和优异的柔性,比起PVC透明度高,光泽好,容易印刷并且具有环保优势。
PCTG材料应用于。Visa公司是 上 的公司之一,1998年其 卡片发行量为5.8亿张。该公司已认可二醇类改性聚酯(PCTG)为其材料。对于要求卡片材料对环境更友好的国家,PETG可替代聚氯乙烯材料。Visa还指出:来自3个不同试验厂的结果显示,PCTG满足国际标准(150/IEC7810)的所有要求,因此PCTG卡片在这里可能得到广泛使用。
异型材:
可成型管材或各种型材,其制品坚硬、透明、光泽好,受压不泛白,易于成型及后加工处理,符合环保要求,同时符合美国FDA关于食品接触标准,广泛应用于建筑装饰及材料。
膜用:专门应用于高性能收缩膜,有大干70%的最终收缩率,可制成复杂外形容器的包装,具有高吸塑力,高透明度,高光泽,低雾度,易于印刷,不易脱落,存储时自然收缩率低的优点,应用于饮料瓶、食品和化;陵品的收缩包装及电子产品等的收缩标签。其中双向拉伸的。PETG膜适用于高档包装、印刷、电子电器、电缆包扎、绝缘材料以及各种工业领域的 基材。单向拉伸PET、热收缩薄膜适用于各种罐装,聚酯瓶、各种容器等外用标签。与PVC收缩膜相比,PETG收缩膜还具有环保的优点。
