简介
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乙二醇-1,4-环己烷二甲醇酯[Poly(1,4-Cyclohexylene Dimethylene Terephthalate Glycol)]。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，最形成无定形聚合物。PCTG中CHDM的含量大于50%。


特性
出众的热成型性能
坚韧性
耐候性
PCTG板材提供了优秀的耐候性。它可以保持产品的坚韧性，防止变黄。它含有紫外线吸收剂，可共挤成一保护层，保护了板材免受紫外线的有害影响。
加工简便
PCTG板材可进行锯切、模切、钻孔、冲孔、剪切、铆接、铣边以及冷弯，不至于破碎。表面的轻微刮痕可用热风枪来消除。溶剂粘接亦是常规操作。它比通用压克力、抗冲改性压克力或PC板更易于加工，并可进行植绒、电镀、静电等加工处理。
优秀的耐化学性能
PCTG板材可以耐受多种化学品以及常用的清洁剂。
环保
PCTG板材基材均为环保材料，符合食品接触管理要求。
经济性
比亚克力经久耐用。


Copolyester forms when modifications are made to polyesters, which are combinations of diacids and diols. For example, by introducing other diacids, such as isophthalic acid (IPA), or other diols, such as cyclohexane dimethanol (CHDM) to the polyester polyethylene terephthalate (PET), the material becomes a copolyester due to its comonomer content.[1]

Copolyesters retain their strength, clarity, and other mechanical properties even when exposed to a variety of chemicals that typically affect other materials, such as polycarbonates. This, plus their versatility and flexibility, allows manufacturers to use them effectively in the design of both high-volume, low-cost parts as well as critical, more expensive component parts.

Applications
Copolyesters offer versatility to meet a wide variety of applications.[1] Copolyester resins have proved to be effective in packaging applications, due to their toughness, versatility and chemical resistance. They are also frequently used in the manufacture and packaging of consumer goods and materials. Markets that rely on copolyesters include medical packaging, home appliances, consumer goods (pens, toys, sporting goods, etc.), and cosmetics, among others.
