CTA介紹：PCTA是一種共聚聚酯塑料原料。具有高透明度，良好的韌性和沖擊強度，優異的低溫韌性，高抗撕性及良好的加工性能，優異的耐化學性能，可電鍍，噴油，抗刮花，密度比PC低16%，加工成本比PC低40%，印刷、著色、電鍍性能佳，韌性比透明ABS高3倍，符合歐洲RoHS環保指令），適用于高檔次的化妝品，電子電氣內材．玩具，高檔筆，并可取代PC在各種領域內的運用。可采取傳統的擠出、注塑、吹塑及吸塑等成型方法進行加工。廣泛應用于板片材、高性能收縮膜、瓶用及異型材市場；可以用來生產玩具、家用器皿及醫療用品等。
PCTA共聚物是環己烷二甲醇和對苯二酸，以及根據需要用別的酸部分取代對苯一酸所形成的聚合物。與PET相比具有較低的可萃取性，更好的耐熱性，低溫抗沖擊性和水解穩定性。可應用于取向和流延薄膜、熱成型盤子和單絲等領域。正常的PCTA共聚酯擠塑薄膜特性有：極亮的透明度、好的低溫韌性、高抗撕性和耐化學性。在合成PCTA共聚酯時改變酸的比例可使聚合物具有不同的*性質。例如可具有高結晶熔融溫度（545F），用于制作可烘烤盤子。PCTA還可以與其它聚酯共混或填充玻纖、云母，以滿足各種性能要求。PCTA共聚酯制品可用于與食品接觸的各種用途，這在FDA規范21CFR—177—12401中已有規定，并也得到USDA許可用作肉禽類包裝材料。原料供應商以美國伊士曼為主。
