CTA介绍：PCTA是一种共聚聚酯塑料原料。具有高透明度，良好的韧性和冲击强度，优异的低温韧性，高抗撕性及良好的加工性能，优异的耐化学性能，可电镀，喷油，抗刮花，密度比PC低16%，加工成本比PC低40%，印刷、著色、电镀性能佳，韧性比透明ABS高3倍，符合欧洲RoHS环保指令），适用于高档次的化妆品，电子电气内材．玩具，高档笔，并可取代PC在各种领域内的运用。可采取传统的挤出、注塑、吹塑及吸塑等成型方法进行加工。广泛应用于板片材、高性能收缩膜、瓶用及异型材市场；可以用来生产玩具、家用器皿及医疗用品等。
PCTA共聚物是环己烷二甲醇和对苯二酸，以及根据需要用别的酸部分取代对苯一酸所形成的聚合物。与PET相比具有较低的可萃取性，更好的耐热性，低温抗冲击性和水解稳定性。可应用于取向和流延薄膜、热成型盘子和单丝等领域。正常的PCTA共聚酯挤塑薄膜特性有：极亮的透明度、好的低温韧性、高抗撕性和耐化学性。在合成PCTA共聚酯时改变酸的比例可使聚合物具有不同的*性质。例如可具有高结晶熔融温度（545F），用于制作可烘烤盘子。PCTA还可以与其它聚酯共混或填充玻纤、云母，以满足各种性能要求。PCTA共聚酯制品可用于与食品接触的各种用途，这在FDA规范21CFR—177—12401中已有规定，并也得到USDA许可用作肉禽类包装材料。原料供应商以美国伊士曼为主。

物性说明
| 产品说明 |
Eastman Cadence™ GS2 is a high-clarity amorphous copolyester for film calendering. Calendered films made of Eastman Cadence™ copolyesters are non-crystallizing, are halogen-free, offer wide calendering and thermoforming windows and have good low-temperature toughness. They are cooperative in secondary operations such as solvent-bonding, lamination, decoration, cold-forming, punching/cutting and embossment.
Eastman Cadence™ resins require no pre-drying or additional stabilizers.
