熱塑性彈性體的優(yōu)點(diǎn)
(1)可用一般的熱塑性塑料成型機(jī)加工，例如注塑成型、擠出成型、吹塑成型、壓縮成型、遞模成型等；
(2)能用橡膠注塑成型機(jī)硫化，時(shí)間可由原來(lái)的20min左右，縮短到1min以內(nèi)；
(3)可用壓出機(jī)成型硫化，壓出速度快、硫化時(shí)間短；
(4)生產(chǎn)過(guò)程中產(chǎn)生的廢料(逸出毛邊、擠出廢膠)和最終出現(xiàn)的廢品，可以直接返回再利用；
(5)用過(guò)的TPE舊品可以簡(jiǎn)單再生之后再次利用，減少環(huán)境污染，擴(kuò)大資源再生來(lái)源；
(6)不需硫化，節(jié)省能源，以高壓軟管生產(chǎn)能耗為例：橡膠為188MJ／kg，TPE為144MJ／kg，可節(jié)能25%以上；
(7)自補(bǔ)強(qiáng)性大，配方大大簡(jiǎn)化，從而使配合劑對(duì)聚合物的影響制約大為減小，質(zhì)量性能更易掌握；
(8)為橡膠工業(yè)開拓新的途徑，擴(kuò)大了橡膠制品應(yīng)用領(lǐng)域。
