澆(jiao)(jiao)注(zhu)型(xing)(xing)(xing)(xing)聚(ju)(ju)(ju)氨酯(zhi)預聚(ju)(ju)(ju)體(ti)(ti)又稱澆(jiao)(jiao)注(zhu)型(xing)(xing)(xing)(xing)聚(ju)(ju)(ju)氨酯(zhi)彈(dan)性(xing)(xing)體(ti)(ti)(CPUE)，簡稱聚(ju)(ju)(ju)氨酯(zhi)cpu澆(jiao)(jiao)注(zhu)機。顧(gu)名思義，“澆(jiao)(jiao)注(zhu)型(xing)(xing)(xing)(xing)”是(shi)指制品在成型(xing)(xing)(xing)(xing)前(qian)物料體(ti)(ti)系(xi)(xi)為液體(ti)(ti)，可澆(jiao)(jiao)筑，反應固化直(zhi)接成型(xing)(xing)(xing)(xing)制品的一種化學加工(gong)方法，而且(qie)該物料體(ti)(ti)系(xi)(xi)中(zhong)原則上(shang)不含(han)揮(hui)發(fa)性(xing)(xing)液體(ti)(ti)。因(yin)為成型(xing)(xing)(xing)(xing)前(qian)該物料體(ti)(ti)系(xi)(xi)為液體(ti)(ti)，而TPU和(he)(he)MPU制品在成型(xing)(xing)(xing)(xing)前(qian)為固體(ti)(ti)，所以也可把CPU稱為液體(ti)(ti)橡膠或液體(ti)(ti)彈(dan)性(xing)(xing)體(ti)(ti)。與TPU和(he)(he)MPU相比，CPU的原材料選擇(ze)范圍(wei)更大，產品硬度范圍(wei)更寬，特別適合于大中(zhong)型(xing)(xing)(xing)(xing)產品的生產，彌補(bu)了TPU和(he)(he)MPU制品加工(gong)工(gong)藝(yi)的局限和(he)(he)不足，可限度發(fa)揮(hui)聚(ju)(ju)(ju)氨酯(zhi)彈(dan)性(xing)(xing)體(ti)(ti)的性(xing)(xing)能優(you)勢，拓寬聚(ju)(ju)(ju)氨酯(zhi)彈(dan)性(xing)(xing)體(ti)(ti)的應用領域。
