為乳白色半透明到不透明、結(jié)晶型熱塑性聚酯。具有高耐熱性、韌性、耐疲勞性，自潤(rùn)滑、低摩擦系數(shù)，耐候性、吸水率低，*為 0.1%，在潮濕環(huán)境中仍保持各種物性（包括電性能），電絕緣性，但體積電阻、介電損耗大。耐熱水、堿類、酸類、油類、但易受鹵化烴侵蝕，耐水解性差，低溫下可迅速結(jié)晶，成型性良好。缺點(diǎn)是缺口沖擊強(qiáng)度低，成型收縮率大。故大部分采用玻璃纖維增強(qiáng)或無機(jī)填充改性，其拉伸強(qiáng)度、彎曲強(qiáng)度可提高一倍以上，熱變形溫度也大幅提高?？梢栽?140℃下長(zhǎng)期工作，玻纖增強(qiáng)后制品縱、橫向收縮率不一致，易使制品發(fā)生翹曲。不易燃燒，燃燒時(shí)無液體流下，離開火焰后在

style="text-indent:25px">聚對(duì)苯二甲酸乙二醇酯PTT纖維:PTT纖維(聚對(duì)苯二甲酸丙二脂)是由于20世紀(jì)90年代中期開發(fā)的一種聚酯類新型纖維。PTT可由1，3-丙二醇(PDO)和對(duì)苯二甲酸二甲酯(DMT)進(jìn)行酯交換后熔融縮聚而成，或由PDO 和對(duì)苯二甲酸(PTA)經(jīng)熔融縮聚而成。PTT纖維表面光潔圓滑，是一種半結(jié)晶狀熱塑性聚酯。它與PBT纖維、PET纖維不同的是在PTT纖維化學(xué)結(jié)構(gòu)中，有一種能量較低的反式-旁式-旁式-反式構(gòu)象并由此呈現(xiàn)出一種明顯的“Z”字形構(gòu)象，同時(shí)在分子鏈結(jié)上PET和PBT上有兩個(gè)亞甲基，而PTT分子鏈鏈接上有三個(gè)亞甲基單元，因此在分子鏈之間會(huì)產(chǎn)生“奇碳效應(yīng)”，這種分子結(jié)構(gòu)使得 PTT 纖維具有如同線圈式彈簧一樣的變形能力且回彈性優(yōu)于 PET 和 PBT。聚丁烯對(duì)苯二甲酸酯具有錦綸的手感柔軟和耐磨性能。沙伯基礎(chǔ)PBT451E</p><p style="text-indent:25px">聚丁烯對(duì)苯二甲酸酯相同特征含有剛性的亞苯基、極性酯基、柔性的亞甲基。沙伯基礎(chǔ)PBT451E</p><p style="text-indent:25px">聚對(duì)苯二甲酸乙二醇酯纖維:PET纖維又名聚對(duì)苯二甲酸乙二醇酯纖維，在我國(guó)常稱為滌綸。目前PET纖維主要采用對(duì)苯二甲酸(PTA)和乙二醇(EG)的直接酯化法或?qū)Ρ蕉姿岫柞?(DMT)與乙二醇(EG)的酯交換法來制得。PET纖維的縱截面與PTT纖維相近，在顯微鏡下呈現(xiàn)的橫截面為圓形，縱向粗細(xì)比較均勻，毛羽少，表面光滑。PET纖維的分子式為 [-OC-Ph-COOCH2CH2O-]n，單基是由一個(gè)苯環(huán)、兩個(gè)酯基和兩個(gè)亞甲基構(gòu)成。由于PET分子中存在苯環(huán)，因此在經(jīng)過傳統(tǒng)的熔體紡絲后需要進(jìn)行拉伸，從而使其快速結(jié)晶，這樣可使得制成的纖維取向度和結(jié)晶度較高，由此生產(chǎn)的PET纖維，具有強(qiáng)度高、彈性好、熱定型性能優(yōu)良、耐熱性好、耐酸堿等性能。沙伯基礎(chǔ)PBT451E</p></p><br
