聚氨酯塑膠跑道材料屬(shu)于(yu)澆注型聚氨(an)酯彈(dan)性體(ti)的一(yi)種，由(you)于(yu)其具有高(gao)(gao)彈(dan)性和高(gao)(gao)耐磨性，越來越多地(di)(di)應(ying)用于(yu)鋪設各種體(ti)育運(yun)動場地(di)(di)，是(shi)目前國際上公(gong)認的運(yun)動場地(di)(di)的鋪裝材料之(zhi)一(yi)。

塑(su)膠跑(pao)(pao)道(dao)(dao)與(yu)煤渣、沙(sha)石(shi)場地相比，具有(you)彈(dan)性好(hao)，吸震性能好(hao)，耐磨和(he)(he)抗老化等優(you)點，不污染環境，易于(yu)清潔和(he)(he)維護管理。自(zi)第19屆奧(ao)運會之(zhi)后，歷屆奧(ao)林匹克運動會的田(tian)徑賽場主跑(pao)(pao)道(dao)(dao)與(yu)輔助(zhu)區均采用塑(su)膠鋪裝，塑(su)膠跑(pao)(pao)道(dao)(dao)已(yi)被國(guo)際公認(ren)為最(zui)佳比賽跑(pao)(pao)道(dao)(dao)。

塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)跑(pao)道(dao)從下到上一(yi)般分(fen)為基礎層(ceng)(ceng)(ceng)和膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)，一(yi)般膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)由彈性(xing)高分(fen)子材(cai)料構(gou)成(cheng)(cheng)，膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)可以是有橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)顆(ke)粒(li)(li)(li)或無顆(ke)粒(li)(li)(li)的塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)跑(pao)道(dao)。膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)主要由聚氨酯材(cai)料組(zu)成(cheng)(cheng)的稱為聚氨酯塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)跑(pao)道(dao)，按(an)原(yuan)料組(zu)分(fen)可分(fen)為單組(zu)份塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)跑(pao)道(dao)、雙(shuang)組(zu)份塑(su)(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)跑(pao)道(dao)；按(an)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)構(gou)造(zao)可分(fen)為全塑(su)(su)型(xing)(xing)(聚氨酯膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)全部采用聚氨酯材(cai)料或橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)(li)(li))、復合型(xing)(xing)(又(you)稱透氣型(xing)(xing)，膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)面(mian)(mian)(mian)層(ceng)(ceng)(ceng)為雙(shuang)層(ceng)(ceng)(ceng)結構(gou)) 、混(hun)合型(xing)(xing)(由PU 膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)(li)(li)或橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)(li)(li)混(hun)合后固化成(cheng)(cheng)型(xing)(xing))。

塑膠跑道(dao)有采用澆注方法直接鋪(pu)設常規跑道(dao)，還有攜帶方便(bian)可(ke)用于(yu)多種場(chang)合折(zhe)疊成(cheng)(cheng)卷的橡膠板形式的便(bian)攜式跑道(dao)。隨著人們環保意識(shi)的提高(gao)和國內市場(chang)的需求，聚氨(an)酯塑膠跑道(dao)將向(xiang)環保、低毒、無害(hai)、低成(cheng)(cheng)本(ben)、高(gao)性能(neng)等方向(xiang)發展。
