PBT為(wei)乳白(bai)色半透明到不(bu)透明、結晶型(xing)熱塑性(xing)(xing)(xing)聚(ju)酯。具有高(gao)耐(nai)(nai)熱性(xing)(xing)(xing)、韌性(xing)(xing)(xing)、耐(nai)(nai)疲(pi)勞(lao)性(xing)(xing)(xing)，自潤滑、低(di)摩擦(ca)系數，耐(nai)(nai)候性(xing)(xing)(xing)、吸水率(lv)低(di)，僅(jin)為(wei)0.1%，在(zai)潮濕環境中仍(reng)保(bao)持各種物性(xing)(xing)(xing)（包括(kuo)電性(xing)(xing)(xing)能(neng)），電絕緣性(xing)(xing)(xing)，但體積電阻、介電損耗(hao)大。耐(nai)(nai)熱水、堿類、酸類、油類、但易受鹵化烴侵(qin)蝕，耐(nai)(nai)水解(jie)性(xing)(xing)(xing)差，低(di)溫下(xia)(xia)可(ke)迅速結晶，成型(xing)性(xing)(xing)(xing)良好。缺(que)點是缺(que)口沖擊(ji)強(qiang)度(du)低(di) ，成型(xing)收(shou)(shou)縮率(lv)大 。故大部分(fen)采用玻(bo)璃纖(xian)維增強(qiang)或無機(ji)填充(chong)改(gai)性(xing)(xing)(xing)，其拉伸強(qiang)度(du)、彎曲(qu)強(qiang)度(du)可(ke)提(ti)(ti)高(gao)一倍以上，熱變形(xing)溫度(du)也大幅提(ti)(ti)高(gao)。可(ke)以在(zai)140℃下(xia)(xia)長期(qi)工作(zuo)，玻(bo)纖(xian)增強(qiang)后(hou)制(zhi)品縱(zong)、橫向收(shou)(shou)縮率(lv)不(bu)一致，易使制(zhi)品發生翹曲(qu)。

Ultradur B 2300 G6 HR Unc. BASF應用：

PBT 結晶速度(du)快，較適(shi)宜加工方法(fa)為注塑，其他方法(fa)還有擠出(chu)、吹塑、涂覆和各種(zhong)二次加工成(cheng)型，成(cheng)型前(qian)需預(yu)干燥，水(shui)(shui)分(fen)含量(liang)要降至0.02%。 PBT（增強、改性PBT）主要用于(yu)汽(qi)車(che)、電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)、工業機(ji)(ji)械(xie)(xie)和聚合物(wu)合金、共(gong)混工業。如(ru)(ru)作為汽(qi)車(che)中的分(fen)配器(qi)(qi)(qi)(qi)、車(che)體(ti)部(bu)(bu)件(jian)(jian)、點(dian)火器(qi)(qi)(qi)(qi)線(xian)圈骨架(jia)(jia)、絕(jue)緣(yuan)蓋、排(pai)氣系統零部(bu)(bu)件(jian)(jian)、摩托(tuo)車(che)點(dian)火器(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)工業中如(ru)(ru)電(dian)(dian)(dian)(dian)視機(ji)(ji)的偏轉線(xian)圈，顯(xian)象管和電(dian)(dian)(dian)(dian)位器(qi)(qi)(qi)(qi)支架(jia)(jia)，伴音輸出(chu)變壓器(qi)(qi)(qi)(qi)骨架(jia)(jia)，適(shi)配器(qi)(qi)(qi)(qi)骨架(jia)(jia)，開關接插件(jian)(jian)、電(dian)(dian)(dian)(dian)風(feng)扇(shan)、電(dian)(dian)(dian)(dian)冰箱、洗衣(yi)機(ji)(ji)電(dian)(dian)(dian)(dian)機(ji)(ji)端蓋、軸(zhou)套(tao)。 另外還有運輸機(ji)(ji)械(xie)(xie)零件(jian)(jian)，縫紉機(ji)(ji)和紡(fang)織機(ji)(ji)械(xie)(xie)零件(jian)(jian)、鐘表外殼、鏡筒、電(dian)(dian)(dian)(dian)熨(yun)斗罩、水(shui)(shui)銀(yin)燈(deng)罩、烘烤爐部(bu)(bu)件(jian)(jian)、電(dian)(dian)(dian)(dian)動(dong)工具(ju)零件(jian)(jian)、屏蔽套(tao)等。
