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)]。
PCTG具有较好的粘性、透明度、颜色、耐化学药剂、和抗应力白化能力。可很快热成型或挤出吹塑成型。粘度比丙烯酸(亚克力)好。
PCTG是一种非晶型共聚酯，其制品高度透明，抗冲击性能优异，特别适宜成型厚壁透明制品，其加工成型性能极，能够按照设计者的意图进行任意形状的设计，可以采用传统的挤出、注塑、吹塑及吸塑等成型方法，可以广泛应用于板片材、高性能收缩膜、瓶用及异型材、化妆品包装等市场，同时其二次加工性能优良，可以进行常规的机加工修饰。

特性
出众的热成型性能
PCTG板材易于生产出造型复杂及拉伸比大的制品。而且，与PC板和抗冲改性的压克力不同，这种板材无须在热成型加工前进行预干燥处理。与PC板或压克力相比，其成型周期短，温度低，成品率更高。
坚韧性
PCTG板材的挤出板材通常比通用压克力坚韧15至20倍，比抗冲改性的压克力坚韧5至10倍。PETG板材在加工、运输和使用过程中具有足够的承受能力，有助于防止破裂。
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。
用途
(1)板、片材
(2) 异型材
(3)化妆品包装


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.
