热塑性(xing)(xing)聚(ju)(ju)(ju)酯(zhi)弹性(xing)(xing)体(ti),又称聚(ju)(ju)(ju)酯(zhi)橡胶(jiao)(jiao),是一种由硬段(聚(ju)(ju)(ju)对苯二甲(jia)酸丁二醇酯(zhi))和软段(脂肪(fang)族聚(ju)(ju)(ju)酯(zhi)或聚(ju)(ju)(ju)醚)组成的(de)(de)(de)高性(xing)(xing)能(neng)嵌段共聚(ju)(ju)(ju)物(wu)。与(yu)工程塑料(liao)相比,热塑性(xing)(xing)聚(ju)(ju)(ju)酯(zhi)弹性(xing)(xing)体(ti)不仅(jin)具有高强度(du)特性(xing)(xing),同时兼(jian)顾橡胶(jiao)(jiao)材料(liao)的(de)(de)(de)柔(rou)韧性(xing)(xing)。热塑性(xing)(xing)聚(ju)(ju)(ju)酯(zhi)弹性(xing)(xing)体(ti)具有优异(yi)的(de)(de)(de)耐化学品、油(you)和溶剂性(xing)(xing)能(neng),出色的(de)(de)(de)耐候(hou)性(xing)(xing)(-70℃-200℃),良好的(de)(de)(de)抗撕(si)裂性(xing)(xing)和耐磨性(xing)(xing),优异(yi)的(de)(de)(de)介电(dian)性(xing)(xing)能(neng)。TPEE与(yu)ABS、PC、聚(ju)(ju)(ju)氯乙(yi)烯等(deng)材料(liao)相容性(xing)(xing)良好。目前TPEE产品主(zhu)要用于:高铁(tie)垫轨、汽车行(xing)业(防(fang)尘(chen)罩、安(an)全气(qi)囊盖板(ban))、工业零部件(液压管、输送带)、体(ti)育(yu)用品(运(yun)动(dong)鞋底)、医(yi)用材料(liao)等(deng)领域。
热(re)塑性(xing)(xing)(xing)(xing)聚(ju)(ju)(ju)(ju)酯弹(dan)性(xing)(xing)(xing)(xing)体(ti)(ti),又称聚(ju)(ju)(ju)(ju)酯橡胶,是一种由硬段(聚(ju)(ju)(ju)(ju)对苯二甲酸丁二醇酯)和(he)软(ruan)段(脂肪族聚(ju)(ju)(ju)(ju)酯或(huo)聚(ju)(ju)(ju)(ju)醚(mi))组成的(de)(de)高(gao)性(xing)(xing)(xing)(xing)能(neng)嵌(qian)段共聚(ju)(ju)(ju)(ju)物(wu)。与工程塑料(liao)相(xiang)比(bi),热(re)塑性(xing)(xing)(xing)(xing)聚(ju)(ju)(ju)(ju)酯弹(dan)性(xing)(xing)(xing)(xing)体(ti)(ti)不仅具(ju)有(you)高(gao)强度特性(xing)(xing)(xing)(xing),同时兼顾橡胶材(cai)料(liao)的(de)(de)柔韧性(xing)(xing)(xing)(xing)。热(re)塑性(xing)(xing)(xing)(xing)聚(ju)(ju)(ju)(ju)酯弹(dan)性(xing)(xing)(xing)(xing)体(ti)(ti)具(ju)有(you)优(you)异(yi)的(de)(de)耐化学品(pin)、油和(he)溶剂性(xing)(xing)(xing)(xing)能(neng),出(chu)色的(de)(de)耐候性(xing)(xing)(xing)(xing)(-70℃-200℃),良好(hao)(hao)的(de)(de)抗(kang)撕(si)裂性(xing)(xing)(xing)(xing)和(he)耐磨性(xing)(xing)(xing)(xing),优(you)异(yi)的(de)(de)介电(dian)性(xing)(xing)(xing)(xing)能(neng)。TPEE与ABS、PC、聚(ju)(ju)(ju)(ju)氯乙烯等(deng)材(cai)料(liao)相(xiang)容性(xing)(xing)(xing)(xing)良好(hao)(hao)。目前TPEE产品(pin)主(zhu)要用(yong)于:高(gao)铁垫轨、汽车行业(防尘罩、安(an)全气囊盖板)、工业零部件(液压管、输送(song)带(dai))、体(ti)(ti)育用(yong)品(pin)(运(yun)动鞋底)、医用(yong)材(cai)料(liao)等(deng)领域。
