Xtel PPS需要足夠的(de)(de)(de)加熱(re)時間(jian),啟動擠出(chu)機(ji)(ji)至關重要的(de)(de)(de)是(shi)確保(bao)穩(wen)定(ding)加工(gong)的(de)(de)(de)溫度(du)(du)(du)(du)。如果溫度(du)(du)(du)(du)不(bu)夠擠出(chu)將造成的(de)(de)(de)阻塞(sai)。 Xtel  XE系列化(hua)合物（Xtel PPS）過(guo)程更擠出(chu)率較高(gao)的(de)(de)(de)地(di)方是(shi)從螺桿融化(hua)而不(bu)是(shi)加熱(re)器(qi)。擠出(chu)機(ji)(ji)應(ying)調(diao)(diao)整到高(gao)于(yu)50％的(de)(de)(de)過(guo)程中運行的(de)(de)(de)溫度(du)(du)(du)(du)，同時盡量(liang)減少停(ting)留時間(jian)。皂(zao)泡(pao)，煙霧或凝(ning)膠都是(shi)在擠出(chu)機(ji)(ji)里過(guo)于(yu)熱(re)，時間(jian)太(tai)久而造成的(de)(de)(de)。溫度(du)(du)(du)(du)適當調(diao)(diao)整，但(dan)模具不(bu)低于(yu)540華氏度(du)(du)(du)(du)（282℃）設置。如果需要熔體溫度(du)(du)(du)(du)降(jiang)低，選的(de)(de)(de)調(diao)(diao)整擠出(chu)機(ji)(ji)的(de)(de)(de)溫度(du)(du)(du)(du)分(fen)布，而不(bu)是(shi)降(jiang)低模具溫度(du)(du)(du)(du)。持續融化(hua)以上600 °F對于(yu)長期的(de)(de)(de)時間(jian)段（315℃）的(de)(de)(de)溫度(du)(du)(du)(du)會導致(zhi)材料熱(re)降(jiang)解(jie)的(de)(de)(de)結果。
