賽鋼料擠出溫度

相關標簽:美國RTP POM、馬來西亞寶理 POM、美國Lucent POM塑化原料、拉絲 POM、醫用級 POM、增韌 POM塑化原料

賽鋼料擠出溫度:180度到210度之間。
應用范圍:賽鋼具有極低的摩擦系數和良好的幾何穩定性,特別適合于制造齒輪和軸承。由于它還具有耐高溫性,因此也用于管道設備(管道閥,泵殼),草坪設備等。注塑模具的工藝條件:干燥:如果材料存放在干燥的環境中,通常不需要干燥。熔融溫度:均聚物材料:190?230℃;190?210C為共聚物材料。模具溫度:80?105℃。為了減少成型后的收縮,可以使用較高的模具溫度。注射壓力:700?1200bar注射速度:中或高注射速度。流道和大門:可以使用任何類型的大門。如果使用隧道門,則較短的類型更好。對于均聚物材料,建議使用熱噴嘴流道。對于共聚物材料,可以使用內部和外部熱流道。化學和物理性質:賽鋼是一種堅韌而有彈性的材料,即使在低溫下也具有良好的抗蠕變性,幾何穩定性和抗沖擊性。賽鋼同時具有均聚物和共聚物材料。均聚物材料具有良好的延展性和抗疲勞性,但是它們不容易加工。共聚物材料具有良好的熱穩定性和化學穩定性,并且易于加工。均聚物和共聚物材料都是結晶材料,并且不容易吸收水分。賽鋼的高度結晶會導致較高的收縮率,收縮率可高達2%至3.5%。各種增強材料的收縮率不同。
